Chopping boards come in a variety of colors, which can be confusing when trying to determine which one to use for different food preparation tasks. The color of a chopping board actually has significance – it provides a visual cue to help prevent cross-contamination during food prep. Each color denotes what type of food the board should be used for. Understanding this color-coding system helps ensure proper food safety when working in the kitchen.
The Reason for Color-Coding
The purpose of using different colored chopping boards for different ingredients is to prevent cross-contamination. Cross-contamination is when bacteria or other harmful pathogens are unintentionally transferred from one food product to another. This often happens when cutting raw meats and produce on the same surface without washing in between. Bacteria from the raw meat can then contaminate the fruits and vegetables, leading to potential foodborne illnesses if consumed.
Color-coding cutting boards provides a straightforward system to keep foods separated during prep. It serves as a visual reminder of which board to use for each ingredient type. The color distinctions make it easy to identify and grab the proper board quickly, lessening the chance of mistakes. It also makes it simple to keep boards designated for only certain food groups. Overall, this coding method is an easy food safety strategy to lower risks in the kitchen.
Common Chopping Board Colors and Uses
Here are the typical chopping board colors and what they denote:
| Color | Food Use |
|---|---|
| Red | Raw meat, pork, lamb, and other meats |
| Yellow | Raw poultry like chicken and turkey |
| Green | Fruits and vegetables |
| Brown | Fish and seafood |
| Blue | Raw food that requires further cooking like steak tartare |
| Purple | Cooked meat |
| White | Bread, dairy and other ready-to-eat foods |
As you can see, each color corresponds with a specific food category or use. Keeping boards separated in this way prevents meat juices, bacteria, and other contaminants from one type of food accidentally transferring to another. Below we’ll look further into the significance of each color and why certain colors are chosen for particular ingredients.
Red Chopping Boards
Red chopping boards are designated for raw meats like beef, pork, lamb, and other red meats. Red is, of course, chosen to match and represent the red, bloody color you see when cutting into raw red meats. Keeping these meats isolated on a red board prevents any of the bacteria present from spreading to other foods. It also helps avoid cross-contamination of allergens, as many people are specifically allergic to red meats.
Yellow Chopping Boards
The yellow board is reserved for raw poultry like whole chickens or chicken breasts. The yellow color easily stands out against the white color of the raw poultry. Chicken, turkey, and other poultry products can contain dangerous pathogens like Salmonella and Campylobacter bacteria. Using a separate yellow board for these raw meats prevents spreading any bacteria. This is especially important given that poultry products are often mishandled or improperly cooked, increasing food poisoning risks.
Green Chopping Boards
The green chopping board is used for all fruits and vegetables. Green represents the color of most produce and is easy to identify. Having a board specifically for produce prevents any bacteria that may be present on meats from contaminating the fruits and veggies. This is particularly important given that many fruits and vegetables are eaten raw in salads and other dishes. A separate green board helps guard against foodborne illnesses.
Brown Chopping Boards
Brown boards are designated for fish and seafood products. The brown color is chosen to match the skin and coloring of many fish. Fish can harbor bacteria and contaminants that could spread to other foods if cut on the same surface. A brown board reserved only for seafoods like fish fillets, shrimp, scallops, and more helps control this cross-contamination. This keeps food prep safe if you’re making a meal with both meat and seafood elements.
Blue Chopping Boards
The blue colored board has a unique purpose – it’s only for raw food intended to be cooked further before eating. This includes things like steak tartare or sushi with raw fish that will be prepared and cooked to specifications. Although these meats are not yet cooked, the blue board signals they will be before consumption, unlike raw chicken that is often fully cooked first. The blue color distinguishes this board to prevent mixing up raw meats for cooking versus immediate eating.
Purple Chopping Boards
Purple boards are used for cooked meats. The color purple doesn’t occur naturally in meat, so it’s easy to visually distinguish that this board is for meat that has already been prepared and cooked. Keeping cooked meats separate prevents any bacteria that may still linger on raw meat boards from contaminating the cooked proteins. This is an important last step in safe handling.
White Chopping Boards
White chopping boards are designated for breads, dairy products, and other ready-to-eat foods that require no additional cooking. The white color denotes food that is safe for immediate eating as opposed to raw ingredients. Keeping these items segregated on a white board also helps control allergen cross-contamination, since many people have dairy allergies. A white board is the safest option for any food that will not be cooked further.
Chopping Board Material Differences
In addition to color-coding, chopping boards come in different materials that have an impact on food prep safety. Here are some common materials and their key characteristics:
Wood – Wood is naturally antimicrobial, so bacteria have a harder time surviving on it. Wood boards require periodic resurfacing/sanding to smooth out knife marks and grooves where bacteria can linger. Do not put wood boards in the dishwasher or soak them for long periods.
Plastic – Plastic boards are inexpensive and dishwasher safe, but plastic can hold onto bacteria more than wood surfaces. Make sure to thoroughly scrub plastic boards after each use. Avoid deep knife markings that can harbor bacteria.
Glass – Glass boards are nonporous and easily sanitized in the dishwasher. However, constant knife contact can damage the hard surface over time. Glass can also dull knife blades faster than wood or plastic. Use caution when handling to avoid breaks/chips.
Bamboo – Bamboo has natural antimicrobial qualities like wood while also being durable. It resists moisture well but still requires occasional resurfacing and handwashing over dishwasher use.
Rubber – Rubber boards are gentle on knife blades yet also nonporous and easy to sanitize. Use caution when handling them as they can discolor from ingredients and are prone to odors.
Proper Chopping Board Cleaning & Maintenance
To use color-coded boards safely:
– Wash hands thoroughly before and after handling different boards.
– Use hot soapy water to clean boards after each use. Sanitize periodically with diluted bleach or vinegar solutions.
– Allow boards to dry fully after washing before the next use. Do not leave damp boards sitting out.
– Replace boards that become excessively worn or develop hard to clean grooves and markings.
– Avoid placing boards in direct dishwasher heat drying cycles as this can damage wood boards.
– Flip boards regularly during use to utilize all surfaces and edges evenly. Rotate out for replacement once they become overly marked up.
– Never use or store boards with cracks or splits that can harbor bacteria.
– Store boards appropriately separated on hooks, not stacked or touching.
Following these best practices for cleaning, storing, and replacing boards helps maximize their safe usage. Be vigilant to use the appropriately colored board for each ingredient as the first line of defense against cross-contamination.
Using Separate Cutting Boards for Meat and Produce
It’s especially important to use different boards when handling raw meat and fresh produce. Unfortunately, many home cooks use the same surface to prep meat and veggies, often without cleaning thoroughly between them. This risks dangerous cross-contamination.
Always start with fresh produce on the green board first before raw meats.Trim and cut all veggies and fruits, transferring them to clean containers or bowls before turning to the meat. Then use the appropriately colored meat board (red for beef, yellow for chicken, etc). Once meats are prepped, immediately discard any trimmings, thoroughly wash knives, clean the meat board, and wash hands again before returning to the green board or other produce.
Never cut produce on a board that held raw meat first. Chemical residues remain that can transfer bacteria onto the fruits and vegetables, even if you can’t see it. Using the color-coded board system prevents this hidden risk. Designate certain boards for meat-only and others produce-only for the safest separation.
Types of Bacteria Transferred by Cutting Boards
Improperly cleaned or misused cutting boards can spread a wide array of dangerous bacteria. Common pathogens passed via contaminated boards include:
– Salmonella – Typically spread from raw poultry and eggs causing fever, stomach cramps, nausea, and diarrhea.
– Campylobacter – Also comes from raw or undercooked poultry. Leads to cramping, abdominal pain, diarrhea, and fever within 2-5 days after ingesting.
– E. coli – Found in raw ground meats, E. coli causes severe gastrointestinal distress 1-8 days after exposure. Usually originates from contaminated beef.
– Listeria – Listeria bacteria causes listeriosis, with flu-like symptoms that can be fatal to certain high-risk groups. It’s found in raw meats and unpasteurized dairy.
– Staphylococcus aureus – Staph food poisoning has symptoms like nausea, vomiting, and diarrhea. Caused by handling cooked or RTE food with contaminated hands or utensils.
– Hepatitis A – A contagious liver infection often transmitted by contaminated food handlers through poor hygiene and infected surfaces like boards.
These are just a sampling of the many dangerous microbes that cutting boards can harbor and spread if not cleaned and sanitized properly. Following color-coded board guidelines greatly reduces this risk of foodborne diseases.
What Counts as a Clean Cutting Board
For a cutting board to be considered clean and safe for additional food prep, keep these key protocols in mind:
– No visible food debris should remain on the surface
– The board should be odor-free with no lingering food smells
– It must be fully dried after washing – no damp patches or moisture
– No deep knife cuts, grooves, or discoloration in the surface material
– It should be sanitized periodically using chlorine bleach or vinegar solutions
– Hot water and soap must be used for scrubbing between each task, no just quick wiping or rinsing
– Hands must be washed before and after handling each separate board
– Boards should not have overlapping use between differing food types or cooked/raw distinctions
Don’t assume running a board under some water or wiping it quickly with a towel renders it clean. Proper scrubbing with hot soapy water, complete drying, sanitizing, and restricted use between foods is vital. Visual inspection along with odor and moisture checks ensures no invisible risks remain before the next usage.
How Often To Replace Cutting Boards
With proper care, most chopping boards can be used safely for many years. However, general guidelines suggest replacing boards once they become excessively worn out or damaged. Recommended replacement timeframes are:
Wood boards – Replace every 1-2 years with heavy use. Up to 5 years for lighter usage in the home kitchen.
Plastic boards – Replace every 3-4 years typically.
Glass boards – Can last 3-5 years normally before swapping out.
Bamboo boards – Rotate every 2-3 years for best results.
Rubber boards – Expect to replace yearly or every 2 years maximum.
Key replacement evaluation factors include:
– Deep grooves, cuts, and markings in the surface that are difficult to clean fully
– Visible cracks, pits, bends and other physical damage or warping
– Discoloration that doesn’t come completely clean even with proper scrubbing
– Odors that stubbornly linger in the material even after washing
– Excessive drying out or damage from high heat if put in the dishwasher
Following the suggested timelines, combined with inspecting for these issues, will indicate when a trusted board should be retired and replaced for maximum food prep safety. Don’t wait until boards are obviously falling apart before getting new ones.
Storing Chopping Boards Correctly
Careful storage extends the usable lifespan of boards and maintains cleanliness between uses:
– Wash, dry, and sanitize boards fully before putting them away
– Choose storage off the counter and in cabinets to reduce contamination risks
– Install hooks, shelving, or racks to keep boards separated if stored together
– Avoid stacking boards directly on top of each other
– Never store boards or cutting mats inside drawers where contamination can occur
– Store wood boards away from excessive heat, moisture, and direct sunlight
– Allow all boards to air dry completely before storage after cleaning
Proper storage limits opportunities for bacteria growth by keeping boards separated and housed away from possible sources of contamination. Ensure boards are not put away with any lingering moisture or food debris through vigorous cleaning and drying first.
Cutting Board Materials To Avoid
Certain materials make poor and risky choices for cutting boards, including:
– Marble, granite, or stone – can dull knives quickly and harbor bacteria in porous grooves
– Stainless steel – damages knife edges and leads to cross-contamination
– Acrylic and melamine – tends to warp, crack, and retain more bacteria
– Unsealed wood products – vulnerable to deep moisture penetration when washed
– End-grain construction – difficult to fully sanitize all the intricate grooves
– Used intact barrels – nearly impossible to clean and sanitize thoroughly
– Copper – can react with certain foods and beverages
While these options seem neat or rustic, they pose real food safety challenges. Stick with traditional recommended wood, plastic, bamboo, rubber, or glass boards that make sanitation easier.
Are Cutting Boards a Food Poisoning Risk?
Cutting boards – especially wood boards – have come under fire through the years as a potential food poisoning risk. Critics argue the porous, grooved material harbors bacteria that contaminates food. However, research demonstrates this is not the case with proper maintenance.
Multiple studies reveal wood’s natural antibacterial properties actually make it safer than plastic for food prep. Wood absorbs less moisture and dries faster while also containing antimicrobial compounds in its lignin and extractives.
The U.S. Department of Agriculture (USDA) found bacteria survives for hours longer on plastic versus wood. As long as wood boards are resurfaced periodically and never soaked in water, they pose very minimal risks. Proper cleaning and restricted food type usage are greater factors than material. The color-coded system makes both wood and plastic boards safe options.
Common Food Safety Mistakes with Cutting Boards
Avoid these frequent cutting board safety errors:
– Forgetting to wash hands before and after touching boards
– Not cleaning between preparing different foods
– Cutting raw meat and produce on same board
– Assuming a quick wipe or rinse sanitizes – use hot water and scrub
– Forgetting to dry boards fully before next use
– Leaving boards or knives out between tasks
– Running wood boards through high heat dishwasher cycles
– Making deep cut marks that become harder to clean
– Using damaged boards with cracks or loose pieces
– Stacking dirty boards together for storage
– Not replacing boards regularly enough
Being mindful to avoid these mistakes will go a long way toward upholding proper food safety. Make cleaning and sanitizing between each usage a habit.
