5S in the Food Industry

Sort, straighten, shine, standardize, and sustain. These five principles comprise the 5S lean manufacturing method that originated in Japan. While 5S can help any organization, the principles contained in the alliterative method should especially appeal to those in food processing for its ability to promote food safety through a clean, safe, and organized workplace.

5S principles are based on the idea that a well organized and clean workplace increases employee satisfaction, promotes worker safety, and decreases product waste. 5S relies on everything having its own place that’s easily identifiable. Like color-coding, 5S uses the idea of a “visual factory” that lets workers know at a glance where tools are and where they should be put back after they’re cleaning.

Sort

For the sort step, work areas should be cleared of things that aren’t needed daily. Discard junk that’s broken or simply not needed, along with broken tools. Items that are needed, but only on an infrequent basis, should be moved to storage. If an item is misplaced or stored illogically, it should be moved to a more convenient location.

Sorting can help minimize chances of cross-contamination and cross-contact by sorting food-contact and non-food-contact items apart from each other.

Set in Order

To set a processing plant in order, it’s important to remember the goal is to increase efficiency in the work environment. This makes it easy for the employee to find the right tool at the right time, thus minimizing chances cross-contamination between raw and finished product. Items should be organized logically, with like items together. Color-coding can be introduced to keep food-contact and non-food-contact items in separate zones and to keep allergens apart where needed. Shadow boards can be used to give every tool a place.

Shine

Tools, machinery and the work area itself should be cleaned as a part of the shine step, which should be repeated as frequently as necessary. Regular cleaning prevents biofilm build-up and increases the facility’s overall hygiene. Factories that deal with particularly sensitive material such as meat or ready-to-eat foods should consider using hygienically designed tools, which are easier to thoroughly clean and sanitize, than standard tools.

Standardize

To standardize, you must first observe the natural flow of workers’ movements. Before writing procedures, watch employees to see where they have consistent methods that work. Take notes on what works, and problem-solve with workers to find solutions to inconsistent and inefficient steps in the process. When you write Standard Operating Procedures or SOPs, consult with employees again on how the entire process should work. The process should feel natural to workers and not be forced. Come up with a training program for new employees, and refresh current employees on the procedures at least yearly, or when there are changes.

Sustain

There are generally three different methods to sustain 5s improvements:

  1. Daily checks

Supervisors should be on the floor and check to make sure procedures are followed daily and to help employees with any process problems.

  1. Periodic checks

Using a 5S checklist, supervisors can perform quarterly or monthly checks to make sure 5S is being followed. They can find and address any problems in these checks.

  1. Change-only checks

Supervisors can check to make sure 5S is being followed only when a process change is being implemented. They can revisit SOPs to integrate the change and to make sure it’s working well for employees.

 

Implementing 5S can help food processing facilities increase hygiene in their organization, as well as increasing their efficiency.

New-Employee-Proof Your Safety Plan with Color Coding

In the food processing industry, like many factory-based jobs, employee turnover is high. When you’re seeing a turnover rate of about 35% yearly, how do you train your staff to follow important safety plans? When you’re in an industry where a simple mistake by a single employee could result in thousands of people getting sick, how do you ensure HACCP compliance?

For many, color coding has become the easiest answer. Color coding offers a simple solution to an otherwise complex problem. Even the newest employee can quickly learn that red products belong with the raw product, and white goes with the finished.

Here are our top 5 tips to using color coding to ensure all of your employees follow CGMPs.

  1. Set up cleaning stations

Cleaning stations serve as a visual reminder that everything has its place. Put a sign over a station filled with blue tools to remind everyone that those tools are used to clean floors in the packing area, and another sign over a pink wall bracket to tell employees that those tools are used in receiving. Cleaning stations also remind employees to hang tools back up once they’ve been cleaned.

  1. Separate allergen control zones

Training new employees on how and why to respect allergen control zones is difficult. Popular culture has made everyone aware of the danger of peanuts, but many people don’t respect the potential harm trace residues of milk ending up in the wrong product can do. Even if your individual employee doesn’t understand why blue tools are only to be used in a certain area, they can at least quickly understand that it’s the way the factory operates. If the new employee still doesn’t respect the separation, they can be quickly corrected, since it will be immediately obvious they’re using a tool outside its zone.

  1. Back up your plan with pictures

It’s riskily idealistic to think every employee who walks through your door will know how to read in English, or know how to read at all. Photos of what to use each tool with will back up your written signs and make them easy to understand for all of your employees, no matter what their background or education level is. Use easy photos like a picture of peanuts with a big red X over them for your peanut-free tools, or a photo of a purple scoop next to wheat grains so employees know what those tools should (and shouldn’t) touch.

  1. Don’t use commonly color-blind colors

When you choose colors, be aware that some are more easily confused than others. Of people with color-blindness, about 99% have trouble distinguishing between red and green. Try not to use these colors in the same color coding plan. Also, be aware of the fact that about one in 12 men are colorblind, and one in 200 women. Choose shades that are contrasting, like white and red, and avoid putting similar shades near each other, like brown and orange or blue and purple.

  1. Use color-coding to spot training issues

Is someone using the brush meant for a different shift or a different area of the facility? It’s time for a small, informal retraining conversation with a floor manager. These easy discussions can essentially boil down to telling the employee the color they should be using for their purpose. Quick one-on-one sessions with a manager will reinforce these guidelines, and with very little time or effort wasted. Floor managers should have color-coded zones memorized so they can make the most of their time on the floor and correct problems where they see them.

 

Food safety is everyone’s job in the plant, but training comes down to managers and owners. Creating an environment where safety comes first starts with using the right tools for the job, and color coding can help with that.

10 Things To Know About Color-Coding: Use Complete Implementation

We’ve come to the final post in our series of 10 things to know when starting or revising a color-coding program. You may have already determined that color-coding is the solution for your facility’s food safety needs. If not, take a look at our previous blog posts in this series, and perhaps you will find some things you have not yet considered.

Vikan Hygienic Zone Planner Application for color-codingThe final key to the success of a color-coding program is ensuring that it is completely integrated into the facility. If you have decided to take the plunge and start a color-coding program, or if you think yours needs some tweaking, remember that even a good color-coding program can be problematic if it is not completely applied. Ensuring complete implementation will improve internal adoption.

Doing something halfway is never a good idea, and the same holds true for color-coding. When a color-coding program is implemented in pieces, the chances of success start to deteriorate. On the surface, it might seem easier to slowly bring in color-coding into your facility; but in the long run, it will be better for everyone to roll the program out all at once. Incomplete implementation might seem desirable due to a limited budget, time constraints, or lack of manpower. No matter what the reason, sometimes you just have to bite the bullet and go all the way. Go big, or go home, as they say. Once it is a part of everyday life at the facility, a color-coding program will be one more asset that you have at your disposal.

If you read our last post, you know that communication plays an integral part of starting a color-coding program. Communication and complete implementation of the color-coding program go hand in hand. By communicating with every employee and team member, complete execution of the color-coding system will be that much more successful.

One issue that might prevent a complete roll-out of a color-coding program is budget concerns. This is a valid issue, and one likely to be shared by many operations. However, because a successfully applied color-coding program can help decrease the chance of cross-contamination, and therefore recalls, it could save money in the long-term. Color-coding a food processing facility is an investment. Just like any investment, there are start-up costs—but the end result will be well worth the money put into it.

In addition to any budget concerns, lack of time and manpower can also be issues standing in the way of introducing a color-coding system into your facility. Every food processing facility, from the smallest to the largest outfits, can benefit from a color-coding program. If time is an issue for you, ask us for help. Remco and Vikan have tools that can help you quickly identify zones and plan the entire program for your facility. We’re here to assist you with the process.

10 Things To Know About Color-Coding: Communication is Key

Essential to an effective color-coding system is a well thought-through communication plan. With the proper communication channels in place, your color-coding system has the best chance for successful adoption—in turn helping you to mitigate the risk of cross-contamination. Communication should start at the top of the company, and go down to each and every employee. When all employees are knowledgeable about the new or changed program, the chances of success are even higher.

HACCP Plan for food safetyThe initial employee training communications must be clear and concise to ensure everyone is on the same page. When starting, or even revising, a color-coding system, employees must understand the reason for the change. Dealing with the threat of cross-contamination is serious, and the need to establish barriers to those threats is critical. The better every employee understands this, the more effective the color-coding system will be when put into practice.

Communicating with employees on how color-coding can help with tool storage is also very important. Establishing procedures for storage can help with tool inventory management. If employees are taught the proper procedures for tool storage right out of the gate, this will go a long way in preventing any loss of tools or time. One particular way to help encourage proper storage is to use custom shadow boards that integrate outlines of the tools so that there is no question where tools belong. Some facilities might use the 5S system to maximize organization. The use of color-coding is a great way to enhance the 5S philosophy. 5S is a Japanese workplace organizational system which uses five phases: sort, set in order, systematic cleaning (or shine), standardize and sustain. Along with using shadow boards, 5S helps encourage employees to properly store tools, maximizing their usable life.

Daily communication to employees is essential to the longevity of the program. Daily communication starts with good signage. Clearly written instructions, bilingual if necessary, are essential to providing employees with instructions on the color-coding program. It may even help to include visual or graphic representations on the signage for each zone; for example, a picture of a peanut on the sign designating the color of tools intended for use with peanuts. In addition to written instructions, daily verbal communication is also vital. Any changes or revisions to the color-coding plan must be clearly communicated to all employees, from the top down.

It is a best practice to include your color-coding program in your official regulatory documentation. Many regulatory bodies require documentation of certain procedures, and color-coding can become a great advantage for your operation. While color-coding is not required for compliance with any food safety regulations, it is looked upon with favor by auditors. Including your color-coding plan in the facility’s Preventive Control or Prerequisite Procedures, which includes GMPs, SOPs, CCPs, and Non-CCPs, will go a long way in ensuring company-wide adoption, consistency and compliance of the program. For facilities that must comply with HACCP or HARPC regulations, including color-coding on those plans is, again, not required but, a best practice. HACCP, or Hazard Analysis & Critical Control Points, is a food safety management system which helps to identify and control cross-contamination threats. Similarly, HARPC, also known as Hazard Analysis and Risk-Based Preventive Controls, also requires identification and control of risks in food processing facilities.

Here are some important things to remember:

  • Start at the top and go down
    • Communicate with all levels of employees to ensure complete implementation
  • Have good signage
    • Signs should have written and visual cues to identify the zone and where the tools are approved for use
    • Include a printout that gives details for reordering of tools, such as vendor, item number, manufacturer, etc.
  • Keep up with training
    • Consistent training programs for all employees will improve adoption and ongoing use of the program
  • Include color-coding on regulatory plans
    • Color-coding is looked upon favorably by regulatory bodies

10 Things To Know About Color-Coding: Keep it Simple

The core piece of advice that Remco communicates to food facilities implementing a color-coding program is to keep it simple. A common paraphrase of Ockham’s Razor, originally written in Latin, is “All things being equal, the simplest solution tends to be the best one.” A color-coding program that is overly complex could become problematic for your facility and end up requiring more time and effort than it should, as well as involving more risk for cross-contamination. Determining what works and what doesn’t is easier with a simple color-coding plan.

Red Vikan Brush Cleaning MachineryFood safety is a challenging endeavor in an industry with complex regulations, and color-coding is intended to simplify an element of it. Completely simplifying food safety is impossible, but color-coding can help, while supporting the overall goal of food safety regulations. Color-coding offers a method to intuitively keep tools organized and clearly communicate which tools belong in certain areas. Visual identification of equipment is quick when tools are color-coded.

The foremost principle to remember regarding the simplicity of a color-coding system is to limit the number of colors used to what is absolutely necessary. For example, many food production operations have determined that only two colors are necessary: one for “food contact” and another for “non-food contact.” A plan like this would ensure that tools used on the floor are easily identified as being different than those intended to be used on food and food contact surfaces. This type of simplistic plan is very easy to explain to employees and communicate throughout the facility.

In cases when more than two colors are necessary, it is advisable to choose colors based on functionality. For example, some food production facilities employ processes that involve cooking raw meat. The potential for cross-contamination between raw and processed zones is a hazard that absolutely must be managed. Typically, two different colors are designated for raw and processed zones, and a third color is chosen to identify equipment designated for non-food contact areas. This type of a plan integrates more colors, but remains intuitive and should only require basic training for employee adoption.

Color-coding can become a method to standardize processes within a plant or a group of plants. Some businesses choose to standardize processes in order to reduce waste and variation in the end product result. This type of standardization can be applied to cleaning tools and sanitation processes, and color-coding is a suitable fit for this type of model. An example of this is to apply the same color-coding model across all production lines that run the same process within a plant. It can be taken a step further and applied across all plants that run the same processes so that only one training program needs to be developed and administered.

Using a color-coding model that is not straightforward can create more of a need for specialized training. For example, a total color-coded red broom and handle is easier to identify than a specialized broom that mixes a green broom head with a red handle. A plan with combo color equipment will require more time and resources to train staff, especially if either color is used elsewhere in the plant. The whole premise of color-coding is to make tools easy to visually identify without the need for in-depth training. Using combo color tools robs a color-coding program of that intuitive simplicity, and in turn requires more resources than necessary for your operation to implement and adopt. It also increases the risk of cross-contamination if employees do not understand the program.

When designing a color-coding program for your operation, remember that the ultimate end goal is to ensure the safety of the food produced in the facility. For each color that you integrate into your plan, ask yourself if it is a necessary step in the process in order to effectively mitigate risk. If a color designation does not serve the purpose of managing a significant food safety risk, it is always the best practice to opt for simplicity. A plan that is overly complex is difficult to communicate and understand. A simple plan is easily adopted and becomes an intuitive method for managing food safety risks.

10 Things to Know About Color-Coding: Breaks Down Language Barriers

The environment in a food processing facility can be a chaotic place. This is compounded when you bring multiple languages into the mix. Trying to keep everything organized and streamlined can at times be a daunting task. Having a color-coding program in place can help eliminate some of the confusion that can arise from a language barrier.

Color-coded storage wall bracket with rubber clipsWhether you have one employee that speaks another language, or 500, color-coding can help to keep efficiency high. Because colors are universal, no matter what language someone speaks, they are going to be able to tell one color from another. Red is red, even if the word itself is different.

If red is for the raw zone, and someone, who speaks a language that the majority of employees do not, sees a red tool in the blue zone, which is for processed product, they know immediately that something is not right, and can then take appropriate actions. However, if no color-coding program is in place, and say, for instance, the method of communication is to have labels on the tools stating what zone they belong in, that employee might not know for sure if that tool is supposed to be there or not. With this kind of system, any time spent confused is loss of work, or worse yet, a cross-contamination hazard. Better to have a proper system in place to begin with, so the problem can be fixed as soon as possible.

But, before you can go putting colors into a facility all willy-nilly, expecting employees to follow along, there must be good documentation and communication of zones. This goes for all people, no matter the language. There must be signage and internal communication that clearly states what these different colors mean, and what the appropriate steps are when something goes wrong, in different languages, if necessary. Once everyone is on the same page, your color-coding system will work that much easier.

What about those who can’t see colors, you might ask? Color blindness can affect about 8% of men and .05% of women. Depending on what kind of color blindness your employee has, choosing colors that have a high contrast might be a solution. Every situation is different, and the most important thing is to know your employees’ needs and how to best meet them.

Having a color-coding program in place can help to limit the language confusion found in food processing facilities. Less confusion means safer practices, and this means better food safety. This can add up to less recalls, which saves money.

10 Things To Know About Color-Coding: Traceability

Recalls are serious business.No one wants to see a recall happen to their company, but all too often it happens. So, it goes without saying that food safety is important. From the field all the way to the table, keeping our food safe has to be top priority.  Knowing where food is coming from, and what happens to it on its way to you, can potentially prevent a catastrophic recall. This is known as traceability. Traceability means being able to verify where food has been every step of the way – to the field it came from, to the line it’s processed on, and what truck carried it. It’s a complex chain of custody, but necessary to monitor in order to protect food consumers.

Traceability food safety field to fork

Tracing the overall process is challenging, but it is as difficult, if not more difficult, to maintain that same control over your own facility, and it’s your responsibility. Many food processing facilities are large outfits with numerous people working on different shifts, and some are small, localized businesses with few staff members. Trying to keep track of food’s movements can prove difficult for big processors and mom-and-pop shops alike, and food safety is important in every single production facility.

Having color-coding in processing facilities can only enhance the level of traceability. Having a color-coding system helps to track tools within the facility, making it that much safer. If you use red for the raw meat zone, then you know that a red tool in the yellow zone, which is for processed food, is a contamination threat. You can then take steps to remove the potentially contaminated food from that area.  This is much easier than trying to remove contaminated food after it has left the facility, which could cost millions of dollars.

The benefit of having tools that are completely color-coded is that they provide instant recognition.  If you see just a glimpse of a tool, it is easier to know where it came from if it is in total color.  To know in an instant the origination of a tool is vital to preventing lost time, production shutdown, and delays. Having tight traceability in food processing facilities can not only diminish the chance of a recall, but it also helps keep your facility on time with deadlines, helps the bottom line, and it looks good in the public and regulators eyes.

In order to effectively trace food through the system, though, there must be consistency between all levels of movement. From the farm to the table, everything should be documented for the highest level of traceability.  With the technology we have at our disposal, there is no reason not to be able to considerably reduce the number of recalls we see.  Food processors should urge their suppliers to practice the same level of consistency with food safety. You may not be able to control what happens outside your facility, but you can choose to use suppliers that do follow best practices.

10 Things to Know About Color-Coding: Regulators Love It

If your business is food processing, you are no stranger to government rules, regulations, and auditors.  Complying with federal food safety regulations is crucial to the success—or even existence—of your operation.  Keeping the auditor happy sometimes becomes a top priority (like, the day before the audit), because no one wants to deal with the time, money, and marred reputation of a production delay or facility shutdown. If you’re looking for ways to strengthen the food safety efforts at your operation, we think you need to know about color-coding—because we guarantee that your auditor does.

Even though color-coding is not a standard rule or even a requirement, it is a practice that regulating authorities commonly favor. Regulatory agencies, like the Food & Drug Administration (FDA) and the U.S. Department of Agriculture (USDA), exist to provide guidance for food safety procedures and ensure the compliance with laws relating to the safety of the nation’s food supply. One such law is the Food Safety Modernization Act (FSMA) that is intended to transform the U.S. food safety framework from a reactive damage control approach to more of a proactive prevention of foodborne illness crises. FSMA Section 103 requires food facilities to prepare written plans to evaluate hazards and implement effective preventive controls. It stipulates several steps to ensure a true preventive approach to food safety.

Regulating authorities look favorably upon the practice of color-coding because it is a method that can easily be documented and followed by employees. A color-coding program that is written into a HACCP plan essentially becomes part of the facility’s SOPs (standard operating procedures). A HACCP plan is a written outline that identifies potential food safety threats and critical control points. Color-coding adds an extra layer of preventive protection in addition to other food safety efforts such as hygienic design of buildings and equipment. Programs that are easily documented are also more easily communicated to employees, and the employees’ adoption of food safety procedures is imperative to the effectiveness of those programs.

Visiting authorities and customers will readily notice color-coding programs upon entering a processing facility, which is precisely why the approach is so effective. Segregating zones by colors offers quick visual confirmation that equipment is where it belongs and is not contributing to the unintentional transport of contaminants throughout the facility. When color-coding is utilized as part of a multi-faceted approach to food safety, it will add credibility to the effectiveness of the operation for regulators and customers alike.

With the new laws and proposed guidelines surrounding food safety, prevention is the preferred approach by regulatory authorities. And in the long run, prevention is a better business practice than reactive damage control. The old saying about closing the barn door after the horse is out comes to mind when thinking about recalls; it’s just better for everyone if a recall doesn’t happen in the first place.

News of recalls can travel in the blink of an eye in the rise of social media.  In that time, the success of your facility can be irreparably damaged. To safeguard your operation from the negative publicity of a food safety crisis, it is imperative to prevent recalls before they happen.  Monitoring any sort of cross-contamination threat inside the facility is fundamental, and color-coding is a simple way to keep those risks in check. To learn more about how color-coding can help, see our preventing cross-contamination blog article.

10 Things to Know About Color-Coding: Guidelines and Best Practices

While the FDA does not currently have any standard set rules to follow when it comes to implementing a color-coding program, there are some common best practices that you can follow to get the most out of color-coding the facility.

Here are some ideas to help you design an effective color-coding program:

Keep your color-coding system simple– Limiting the number of colors you use will go a long way in simplifying the process. Too many times, people get bogged down with the idea that every line and every single process has to have a different color. This is not the case. Try to have a different color only when cross-contamination is a concern at a critical control point in the process. Those points where control is not needed could potentially use the same color, since cross-contamination is not a threat.  The more colors in the mix, the more confusing it becomes, and the less effective it will be.

Pick logical colors for each area-Making the transition to a color-coding system needs to be as seamless as possible. In order to keep confusion low, when stepping into this system, try to pick colors that make the most sense in each area. For example, certain colors might make sense for certain areas in your food processing facility, such as red for raw meat, or yellow for wheat. Do what is most logical for your facility. Also, make sure that it makes sense to both managers and employees. If everyone is on the same page, the transition will run more smoothly.

Avoid complicated color assignments-Having customized tools, like a different colored handle than the broom, might seem like a great idea to help differentiate zones. However, it does lead to confusion.  If you mix and match handles and brushes the end result might be chaos.  Say you have a red broom with a green handle (Merry Christmas?).  Now, you have the problem of trying to figure out if it goes in the green zone or the red zone. Save everyone the confusion, and stick to one color per zone. Instant recognition is the key to keeping confusion to a minimum.  You should be able to look quickly and determine which zone is which.

Roll out the color-coding program all at one time– This goes back to avoiding confusion. If you try to incorporate the new system in with the old one, people are just going to be confused. It’s best to start the program all at once. It might be more difficult in the beginning, but it will be worth it in the end. Also, having a definite end date to the old program and a definite start date for the new system will make the transition even smoother.

Good communication is key– Having everyone on the same page will help with starting your color-coding program.  A good practice is to first discuss the changes with shift managers, then roll it out to the employees.  The mangers should have a good understand of the new system so they can address any questions or concerns the employees might have. Offering a cheat sheet to employees that explains the color zones will be tremendously helpful in overall adoption of the program.

Reinforce the color-coding with good signage-When starting a color-coding program, you don’t want any ambiguity in how it’s perceived. Make it absolutely clear what the program is, and when it is starting. The best thing to do is label every point in the process, in multiple languages if necessary.

Be sure your tools and storage areas match– Be sure the tools are stored in the same area where they are used to avoid confusion, cross-contamination, and equipment loss.  If the red tools are stored on a red bracket or red shelf, it is easy to see exactly where that tool should go when it isn’t in use. Having an organized storage area will be very helpful in maintaining the integrity of the color-coding system.

Follow through– Utilize the same documentation at point of use, with the purchasing department and with the quality manager so everyone is on the same page.  Making sure all loose ends are tied up will help exponentially to the success of the color-coding program. If the program is successful, your facility will be much safer.

10 Things to Know About Color-Coding: Zones and Critical Control Points

Understanding Zones and Critical Control Points in Color-coding

Just about every food processor knows that complying with food safety regulations from the FDA and other regulatory bodies is a vital aspect to the success of their overall operation. Without achieving this compliance, it would be fairly difficult to run an effective food processing program. The list of recalled food products seems to grow every day, most being the result of some sort of cross-contamination, and those recalls can cost millions of dollars. The old adage, “better safe than sorry,” definitely comes into play when talking about protecting against recalls. Color-coding is one simple method to help keep your food processing operation as “safe” as possible.

One of the most important FDA-proposed rules is HACCP. Complying with HACCP regulations is an important part of any food processing operation, and knowing where the critical zones are and preventing cross-contamination from happening is an integral part of this compliance. Currently, there are HACCP procedures for dairy, juice, retail seafood, and retail and food service.

Let’s back up for a second, HACCP stands for Hazard Analysis and Critical Control Points. HACCP is a preventative approach to the identification, evaluation, and control of food safety hazards that may cause illness or injury when not properly controlled. Put simply, HACCP is designed to help control the threat of cross-contamination from biological, chemical, and physical agents. According to the FDA, “any action or activity that can be used to prevent, eliminate or reduce a significant hazard” is considered a control measure. Color-coding is an excellent example of a control measure.

Once potential food safety hazards are identified, critical control points can be documented. The FDA defines a critical control point in a food manufacturing process as “a step at which control can be applied and is essential to prevent or eliminate a food safety hazard or reduce it to an acceptable level.” Knowing where the critical control points exist in a food production process is essential to designing an effective HACCP plan.

Included in the many HACCP compliance resources available from the FDA is an example of a decision tree to help a food processing operation identify critical control points, seen below. Using a decision tree like this is not a mandatory part of the process, but it is valuable as a tool to facilitate the development of a thorough food safety program.

FDA Example of Decision Tree

Since color-coding is a control measure, color-coding zones often coincide with critical control points or groups of critical control points. For instance, a color zone may be assigned to an area where raw meat exists in a facility, since raw meat poses increased risks of bacterial contamination. There may be several critical control points that require other control measures within that one color zone, such as testing for contaminants or refrigeration of the raw meat prior to processing. Once the meat has been cooked, a different color may be assigned to the zone following the raw meat area to prevent bacterial cross-contamination into the finished product. For this purpose, color-coding is an excellent and simple way to visually confirm that equipment is in the appropriate critical zone in a food processing facility.

When color-coding is implemented, it is easily apparent which zones are which, and what they represent. Because of this instant recognition, separating contaminated food before it goes out to the public becomes easier. And we all know that internal recalls (or no recalls!) are less costly than public recalls.
