What are three of the four times when food contact surfaces need to be cleaned and sanitized?

Did you know that an estimated 1 in 6 Americans will get sick from food poisoning this year alone? Food poisoning not only sends 128,000 Americans to the hospital each year—it can also cause long-term health problems. You can help keep your family safe from food poisoning at home by following these four simple steps: clean, separate, cook and, chill.

Clean: Wash Hands, Utensils, and Surfaces Often

Germs that can make you sick can survive in many places around your kitchen, including your food, hands, utensils, cutting boards, and countertops.

Wash your hands the right way:

  • Use plain soap and water—skip the antibacterial soap—and scrub the backs of your hands, between your fingers, and under your nails for at least 20 seconds. Need a timer? Hum the “Happy Birthday” song from beginning to end twice.
  • Rinse hands, then dry with a clean towel.
  • Wash your hands often, especially during these key times when germs can spread:
    • Beforeduring, and after preparing food
    • After handling raw meat, poultry, seafood, or their juices, or uncooked eggs
    • Before eating
    • After using the toilet
    • After changing diapers or cleaning up a child who has used the toilet
    • After touching an animal, animal feed, or animal waste
    • After touching garbage
    • Before and after caring for someone who is sick
    • Before and after treating a cut or wound
    • After blowing your nose, coughing, or sneezing
    • After handling pet food or pet treats.

Wash surfaces and utensils after each use:

  • Wash cutting boards, dishes, utensils, and countertops with hot, soapy water, especially after they’ve held raw meat, poultry, seafood, or eggs.
  • Wash dish cloths often in the hot cycle of your washing machine.

Wash fruits and vegetables, but not meat, poultry, or eggs:

  • Rinse fruits and vegetables under running water without soap, bleach, or commercial produce washes.
  • Rinse fruits and vegetables before peeling, removing skin, or cutting away any damaged or bruised areas.
  • Scrub firm produce like melons or cucumbers with a clean produce brush.
  • Dry produce with a paper towel or clean cloth towel.
  • Don’t wash meat, poultry, eggs, or seafood to avoid spreading harmful germs around your kitchen.
  • Produce labeled as “pre-washed” does not need to be washed again.

Separate: Don’t Cross Contaminate

Use separate cutting boards and plates for produce, meat, poultry, seafood, and eggs:

  • Use one cutting board for fresh produce or other foods that won’t be cooked before they’re eaten, and another for raw meat, poultry, or seafood. Replace them when they are worn.
  • Use separate plates and utensils for cooked and raw foods.
  • Use hot, soapy water to thoroughly wash plates, utensils, and cutting boards that touched raw meat, poultry, seafood, eggs, or flour.

Keep certain types of food separate:

  • In your shopping cart, separate raw meat, poultry, seafood, and eggs from other foods and place packages of raw meat, poultry, and seafood in plastic bags if available. When you check out, place raw meat, poultry, and seafood in separate bags from other foods. 
  • At home, place raw meat, poultry, and seafood in containers or sealed, leakproof plastic bags. Freeze them if you’re not planning to use them within a few days.
  • In the fridge, keep eggs in their original carton and store them in the main compartment—not in the door.

Cook to the Right Temperature

Food is safely cooked when the internal temperature is high enough to kill germs that can make you sick:

  • Use a food thermometer to be sure your food is safe. When you think your food is done, place the food thermometer in the thickest part of the food, making sure not to touch bone, fat, or gristle.
  • Refer to our Minimum Cooking Temperatures Chart to be sure your foods have reached a safe temperature.

Keep food hot (140˚F or above) after cooking:

If you’re not serving food right after cooking, keep it out of the temperature danger zone (between 40°F -140°F) where germs grow rapidly by using a heat source like a chafing dish, warming tray, or slow cooker.

Microwave food thoroughly (165˚F or above):

  • Read package directions for cooking and follow them exactly to make sure food is thoroughly cooked.
  • If the food label says, “Let stand for x minutes after cooking,” follow the directions — letting microwaved food sit for a few minutes allows food to cook thoroughly as colder areas absorb heat from hotter areas.
  • Stir food in the middle of heating. Follow package directions for commercially prepared frozen food; some are not designed to be stirred while heating.

Follow special guidelines for barbeques and smokers:

Chill: Refrigerate and Freeze Food Properly

Refrigerate perishable foods within 2 hours:

  • Bacteria that cause food poisoning multiply quickest between 40°F and 140°F.
  • Your refrigerator should be set to 40°F or below and your freezer to 0°F or below. Use an appliance thermometer to be sure.
  • Never leave perishable foods out of refrigeration for more than 2 hours. If the food is exposed to temperatures above 90°F (like a hot car or summer picnic), refrigerate it within 1 hour.
  • Leftovers should be placed in shallow containers and refrigerated promptly to allow quick cooling.
  • Never thaw or marinate foods on the counter. The safest way to thaw or marinate meat, poultry, and seafood is in the refrigerator.
  • Freezing does not destroy harmful germs, but it does keep food safe until you can cook it.
  • Know when to throw out food by checking our Safe Storage Times chart. Be sure you throw food out before harmful bacteria grow.

Cleaners must be stable, noncorrosive and safe to use. When using them: follow the manufacturers' instructions; do not use one type of detergent in place of another unless the intended use is the same.

Surfaces can be sanitized using: Heat (the water must be at least 171℉ and immerse the item for 30 seconds); or Chemicals (Chlorine, Iodine, or Quaternary Ammonia (Quats)).

Chemical sanitizing: food-contact surfaces can be sanitized by soaking them in a sanitizing solution or rinsing, swabbing, or spraying them with a sanitizing solution. In some cased a detergent-sanitizer blend can be used (use it once to clean and a second time to sanitize.)

Sanitizer Effectiveness Concentration: Sanitizers should be mixed with water to the correct concentration: not enough sanitizer may make the solution weak and useless. Too much sanitizer may make the solution too strong, unsafe, toxic, and may corrode metal. Check concentration with a test kit; make sure it is designed for the sanitizer used; check the concentration often. Change the solution when: it is dirty; or with the concentration is too low. Follow manufacturer's recommendations for the correct temperature. The sanitizer must make contact with the object for a specific amount of time. Minimum times differ for each sanitizer. Find out what your water hardness and pH is from your municipality. Work with your supplier to identify the correct amount of sanitizer to use.

General Guidelines for the Effective Use of Chlorine, Iodine, and Quats

Chlorine Iodine Quats
Water temperature ≥100℉ ≥75℉ 68℉ 75℉
Water pH ≤10 ≤8 ≥5 or as per manufacturer recommnedation as per manufacturer recommnedation
Water hardness As per manufacturers recommendation As per manufacturers recommendation ≤500 ppm or as per manufacturers recommendation
Sanitizer concentration 50-99 ppm 50-99 ppm 12.5-25 ppm as per manufacturer recommnedation
Sanitizer contact time ≥ 7 seconds ≥ 7 seconds ≥ 30 seconds ≥ 30 seconds

Steps for cleaning and sanitizing surfaces are: scrape or remove food bits, wash, rinse, sanitize, and air dry.
    All food contact surfaces need to be cleaned and sanitized at these times:
  • After they are used
  • Before foodhandlers start working with different type of food
  • Any time an interruption takes place during a task and the items being used may become contaminated
  • After four hours of continual use

When Cleaning and Sanitizing Stationary Equipment: Unplug the equipment; take the removable parts off the equipment; wash, rinse, and sanitize them by hand or run the parts through a dishwasher if allowed; scrape or remove food from the equipment surfaces; wash the equipment surfaces; rinse the equipment surfaces with clean water; sanitize the equipment surfaces; make sure the sanitizer comes in contact with each surface; allow all surfaces to airdry; put the unit back together.

High temperature dishwashing machines have a sanitizing temperature of 180℉ in the final rinse cycle. Chemical-sanitizing machines clean and sanitize items at a much lower temperature (120℉) than other dishwashing machine.

Dishwashing Operation Guidelines: Clean the machine as often as needed: scrape, rinse, or soak items before washing; use the correct dish racks; NEVER overload dish racks; air-dry all items; check the machine's water temperature and pressure.

Setting up a three-compartment sink: Clean and sanitize each sink and drain board; fill the first sink with detergent and water at least 110℉ ; fill the second sink with clean water; fill the third sink with water and sanitizer to the correct concentration; provide a clock with a second hand to let food handlers know how long items have been in the sanitizer.

Steps for cleaning and sanitizing in a three compartment sink: rinse, scrape, or soak items before washing them; wash items in the first sink; rinse items in the second sink; sanitize items in the third sink; air-dry items on a clean and sanitized surface.

When storing clean and sanitized tableware and equipment; store them at least six inches (15 centimeters) off the floor; clean and sanitize drawers and shelves before items are stored; store glasses and cups upside down on a clean and sanitized shelf or rack; store flatware and utensils with handle up; cover the food-contact surfaces of stationary equipment until ready for use; and clean and sanitize trays and carts used to carry clean tableware and utensils.

Clean nonfood-contact surfaces regularly (includes floors, ceilings, walls, equipment exteriors, etc.): Prevent dust, dirt, food residue and other debris from building up. Develop a plan for cleaning up diarrhea and vomit in the operation. It can carry Norovirus, which is highly contagious. Correct cleanup can prevent food from becoming contaminated and others from getting sick. Consider the following when developing a plan for cleaning up of vomit and diarrhea: How you will contain liquid and airborne substances, and remove them from the operation; how you will clean, sanitize, and disinfect surfaces; when to throw out food that may have been contaminated; what equipment needed to clean up these substances, and how it will be cleaned and disinfected after use; when a food handler must wear personal protective equipment; how staff will be notified of the correct procedures for containing, cleaning, and disinfecting these substances; how to segregate contaminated areas from other areas; when staff must be restricted from working with or around food, or excluded from working in the operation; how sick customers will be quickly removed from the operation; and, how the cleaning plan will be implemented.

Store cleaning tools and chemicals in a separate area away from food and prep areas. NEVER dump mop water or other liquid waste into toilets or urinals; NEVER clean tools in sinks used for handwashing, food prep, dish washing. The Occupational Safety and Health Administration (OSHA) has requirements for using chemicals in foodservice operations. OSHA requires chemical manufacturers and suppliers to provide Material Safety Data Sheets (MSDS) for every hazardous chemical they sell. The sheets contain information about the chemical; safe use and handling; physical, health, fire, and reactivity hazards; precautions; protective equipment to wear; manufacturer's name, address, and phone number; preparation date of MSDS; and hazardous ingredients and identity information. MSDS are usually sent with chemicals delivered. MSDS must be kept visible and available to employees of the operation at all times. Foodservice Chemicals: Only purchase those approved for use in foodservice operations; store them in their original containers away from food and food-prep areas. If transferring them to a new container, label it with the common name of the chemical; keep MSDS for each chemical. When throwing chemicals out, follow instructions on the label and local regulatory requirements.

Cleaning Program To develop an effective cleaning program, create a master cleaning schedule; train your staff to follow it; and monitor the program to make sure it works. To create a master cleaning schedule, identify: what should be cleaned; who should clean it; when it should be cleaned; and how it should be cleaned. When monitoring the cleaning program: supervise the daily cleaning routines; check the cleaning tasks against the master schedule every day; change the master schedule as needed; and ask the staff for input on the program. When developing a cleaning program for a food operation, training employees to follow the program is the key to its success.
