What is Cross-Contamination?
Cross-contamination is a big worry in food safety. It happens when harmful bacteria, viruses, allergens, or chemicals move from one thing to another3. This can lead to foodborne illnesses, severe allergic reactions, or other health problems34.
Types of Cross-Contamination
There are many ways cross-contamination can happen in food places. These include:
- Bacterial and Viral Cross-Contamination – When harmful germs move from one thing to another, causing sickness.
- Cross-Contamination with Allergens – When food allergens get into food by mistake, causing bad reactions in some people4.
- Chemical Cross-Contamination – When dangerous chemicals move from one thing to another, making food unsafe.
Cross-Contamination by Transfer Method
Cross-contamination can also be grouped by how it happens, like:
- Food-to-Food – When one food touches another, sharing contaminants.
- Equipment-to-Food – Using tools or surfaces that aren’t clean and safe.
- Person-to-Food – When people handling food don’t wash their hands properly4.
Stopping cross-contamination is key to keeping food safe and protecting health. Handling food right, cleaning well, and keeping things clean are important to avoid cross-contamination in food places34.
Bacterial and Viral Cross-Contamination
Cross-contamination is when harmful germs move from one surface or food to another. This is a big risk for food safety. Bacteria and viruses are the main culprits, causing diseases5. They grow fast in certain temperatures and spread easily, leading to serious foodborne illnesses6.
Four of the “Big 6” foodborne illnesses are caused by bacteria like Shigella and E. coli. The other two are viruses: Hepatitis A and Norovirus5. These germs spread through touching food, equipment, and people, making it a big concern5.
Food-to-food cross-contamination can happen when meat juices touch cooked veggies in the fridge or when raw chicken meets a steak on the grill5. Person-to-food contamination occurs when hands touch raw meat and then vegetables without washing, or using a dirty apron to clean hands5. Equipment-to-food contamination happens when things like slicers aren’t cleaned between uses5.
To stop cross-contamination, follow food safety steps like washing hands and cleaning surfaces. Store foods right and use different equipment for different foods5. Clean and sanitize surfaces every 4 hours, or after the last use of the day5.
Knowing the risks of cross-contamination and taking steps to prevent it helps keep customers safe from foodborne illnesses67.
“Cross-contamination can lead to foodborne illnesses, which can put people at risk.”6

Cross-Contamination with Allergens
Allergens are proteins that can cause allergic reactions in some people. They can move between foods during handling, storage, and preparation. It’s important to prevent allergen cross-contamination to keep people with food allergies safe8.
Common Food Allergens
Common food allergens include eggs, milk, soy, peanuts, tree nuts, wheat, fish, and shellfish9. Gluten intolerance also needs careful handling to avoid cross-contamination. It’s key to keep these allergens away from other foods for safety.
Food can become contaminated by touching other foods, like nuts on a salad8. Objects like cookware and utensils can also spread allergens if not cleaned well8. Even touching food with your mouth or from pets can spread allergens8. In food production, allergens can mix in shared facilities or with ingredients from suppliers8.
In Canada, food labels can warn about possible allergens, but it’s up to the manufacturer8. The Canadian Food Inspection Agency checks on food safety and labels8.
A study showed soap and water or hand-wipes work better than sanitizers for removing peanut residue8. It’s best not to share food or items to avoid allergens8. Clean cookware and utensils well to prevent allergic reactions8. Using disposable items like paper towels helps keep allergens away from sponges or towels8.
About 90% of food allergies in the U.S. come from the top 9 allergens9. Direct contact means touching foods together, like croutons in a salad9. Indirect contact means using tools or surfaces that touched an allergen on safe food9.
Cook allergy-safe foods first to avoid cross-contact9. If you touch an allergen, even a little bit, you must start over9. Wash your hands with soap and water after touching an allergen, as sanitizers or water alone won’t do the job9.
Clean counters and tables with soap or disinfectant to stop cross-contact9. Wash utensils in a dishwasher or with hot water and soap, then dry them to prevent allergens9. Don’t share food or items to keep kids safe and teach them about it at school or with friends9.
Chemical Cross-Contamination
Chemical cross-contamination is a big worry in the food industry. Restaurants use many cleaning products to fight biological contamination. But, using these chemicals wrong or storing them badly can lead to contaminated10. It’s key to store and handle these chemicals right to stop them from getting into food or surfaces that touch food.
Chemicals can come from things like cleaning agents, fruits and veggies not washed, plastics not meant for food, pest control stuff, and wrong use of kitchen tools11. These chemicals can be very harmful if they get into the food we make.
To lower the risk of chemical cross-contamination, places that serve food must follow strict safety steps. This means:
- Labeling and keeping all cleaning chemicals away from where food is made
- Rinsing surfaces and equipment well after cleaning
- Teaching staff how to safely handle and use chemicals
- Checking for and fixing any chemical contamination risks
By doing these things, food places can greatly cut down on chemical cross-contamination. This helps keep their food safe and of high quality for customers10.
| Potential Chemical Contaminants | Potential Risks |
|---|---|
| Cleaning products (e.g., bleach, sanitizers) | Skin and breathing problems, swallowing by accident |
| Pesticides and herbicides | Poisoning, health problems over time |
| Toxic chemicals in metals or plastics | Heavy metal poisoning, messing with hormones |
| Naturally-occurring toxins (e.g., glycoalkaloids in potatoes) | Food poisoning, harm to organs |
Knowing about chemical contaminants and following strict safety steps helps food places stop chemical cross-contamination. This keeps the food safety of their work1112.
“Proper handling and storage of cleaning chemicals is critical to prevent cross-contamination and ensure the safety of the food we serve.”
Food-to-Food Cross-Contamination
Food safety is a big deal, and cross-contamination is a major concern. Food-to-food contamination happens when harmful bacteria move from one food to another13. This is a big problem with foods that can easily grow harmful germs.
Potentially Hazardous Foods (PHFs)
Some foods are more likely to grow harmful germs. These include leafy greens, raw eggs or meat, and unpasteurized milk13. It’s also important to be careful with soft cheeses, deli meats, and bean sprouts. And don’t forget about leftovers.
Food-to-food contamination is a big reason why there are3 48 million cases of foodborne illness in the U.S. each year. These illnesses lead to3 about 128,000 hospital visits and3 around 3,000 deaths13. Keeping food safe is key to avoiding these risks.
“It is estimated that following good food safety practices can prevent 85% of foodborne illnesses.”13
Here are some ways to avoid cross-contamination:
- Keep raw and cooked foods separate

- Cook foods to the right temperature
- Don’t use the same tools for raw and cooked foods
By knowing the risks and following best practices, we can all help make food safer. This helps reduce the chance of getting sick from food133.
Equipment-to-Food Cross-Contamination
Equipment-to-food cross-contamination is a big worry in the food industry. Cross-contamination means moving harmful bacteria or viruses from one thing to another during food. This is a common problem14. Some germs, allergens, and chemicals can stay alive on surfaces for a long time. Any surface that touches food can spread contamination, known as food contact surfaces14.
It’s key to clean and disinfect properly to stop equipment from contaminating food14. This means washing, cleaning, rinsing, and sanitizing equipment14. The water used for cleaning must be safe and free of germs14. Designers of equipment should think about how to stop germs from hiding in small spaces, making it hard to clean14.
Stainless steel is often used for food equipment because it doesn’t rust easily and is easy to clean14. Titanium is good for handling foods that are very salty or acidic14. Pneumatic parts are also used because they are clean and easy to clean14.
Stopping cross-contamination is key to keeping food safe and quality in processing facilities.15 Food and drink makers use many steps like cleaning, keeping things separate, using color-coded tools, controlling allergens, and training staff to stop cross-contamination15.
By following these steps and keeping things clean, food service workers can lower the risk of cross-contamination. This helps keep the food safe and of good quality141615.
Person-to-Food Cross-Contamination
In the food industry, direct contact between people and food is a common source of cross-contamination17. Food workers who come to work sick can spread germs to the food they touch18. Not washing hands properly can also transfer harmful substances from hands to food18.
To stop cross-contamination, food workers must follow strict safety rules18. They should wash their hands with soap and water before and after touching food, especially after using the bathroom or touching their face18. They should also know when they’re sick and stay home to keep from spreading germs18.
Keeping the work area clean and sanitized is also key17. Cleaning and disinfecting cookware and surfaces helps remove germs from hands or other sources17.
