Handling and Storing Food Safely
I. Keep Your Hands Clean
The most important thing that we can do to protect ourselves is to wash our hands regularly. By frequently washing your hands, you wash away germs that you may have picked up from other people, or from contaminated surfaces, or from animals. Once our hands pick up germs from other sources, we can easily infect ourselves when we touch our eyes, nose, or mouth or infect others through contaminating food or food preparation surfaces.
Remember that, in addition to colds, some pretty serious diseases, including hepatitis A, meningitis, and infectious diarrhea, can easily be prevented if we make a habit of washing our hands often. It is especially important to wash our hands both before and after preparing or handling food, before eating, after using the bathroom, or after playing with our pets. If someone is sick in your home, washing your hands more frequently will help to protect you from becoming sick as well.
Believe it or not, there is actually a right and wrong way to wash your hands. Experts recommend that hands be washed in a combination of soap and warm water for at least 20 seconds. First, thoroughly wet your hands, then apply liquid or clean bar soap. Next, rub your hands vigorously together for several seconds and scrub all surfaces. Rinse well and dry. Keep in mind that it's the soap combined with the scrubbing action that helps to dislodge and remove the germs.
II. Keep Surface Areas Clean, Too
Bacteria are everywhere in the environment and can grow quickly and easily if we don't observe proper cleaning and sanitation procedures.
There is a difference between cleaning and disinfecting. Cleaning generally means that dirt is being removed, while the term disinfecting means that germs are being removed. While surfaces may look clean, many infectious germs can be lurking. Under certain conditions, some germs can live on surfaces for hours and even for days.
Tips for Keeping a Clean Kitchen
Kitchens can be one of the most dangerous places in the home because of the infectious bacteria that can be found on raw foods. We can also spread germs to other people through the handling and food preparation process if we are not careful. In addition to washing our hands before we begin preparing food, we should make sure to wash our hands after handling any raw food product to make sure we do not transfer any bacteria from the raw food to foods we plan to handle next.
- Dishes and Utensils: Make sure to thoroughly wash your dishes and utensils with hot soapy water and to rinse them thoroughly. If you need to use the same dish or piece of equipment more than once, wash and rinse it thoroughly before you switch to the next food product.
- Cutting Boards: Make sure your cutting boards are made of non-porous material or plastic. Wash your cutting boards in hot soapy water and rinse thoroughly after each use.
- Sponges: Sponges are not recommended for cleaning food preparation areas as they can harbor bacteria. Cloth towels or paper towels are acceptable for use. Cloth towels used in food preparation areas should be washed frequently on your washing machine's hot cycle. Paper towels can be used to clean up food spills and to clean food preparation areas, but they should be immediately disposed of when finished cleaning.
- Countertops: Countertops should be thoroughly cleaned with hot soapy water before you begin to prepare food and again after coming into contact with any food products. As noted above, sponges are not recommended for use in cleaning food preparation areas such as countertops because they can harbor bacteria. Also, make sure to use only those cleaning products designed and tested for use in food preparation areas, and use them according to the manufacturer's instructions. Products not designed or tested for use in food preparation may leave harmful residues.
Cleaning and Disinfecting Surfaces
It is important that we use care when cleaning and sanitizing surfaces in our homes. Some cleaning products can adversely affect our ability to breath or cause a severe skin reaction in some individuals. Protect yourself and observe the following tips:
- Always make sure to read and follow the directions on the label of the cleaning products. Read and follow all safety precautions recommended by the manufacturer.
- Use rubber gloves when cleaning blood, vomit, or other bodily fluids. This is particularly important if you have any open wounds or if a family member has a bloodborne disease such as HIV or hepatitis.
- After cleaning and disinfecting, wipe the surface with paper towels that can be thrown away or cloth towels that can be washed afterwards. Cloth towels should be washed using the sanitation cycle on your washing machine (or the hottest cycle if a sanitation cycle is not available).
III. Don't Cross-Contaminate
Improper handling of raw meat, poultry, or seafood can create an inviting environment that is perfect for cross-contamination. If we're not careful when handling these foods, bacteria can quickly spread between food products and throughout your kitchen.
Tips to Avoid Cross-Contamination
- Keep it clean. Always wash hands, cutting boards, dishes, and utensils with hot, soapy water after they come in contact with raw meat, poultry, or other raw foods.
- Use separate surfaces. If possible, use one cutting board for fresh produce and use a separate one for raw meat, poultry, and seafood. If you only have one cutting board, wash with hot water and soap and rinse thoroughly before using it for the next food item.
- Separate foods. Try to separate raw meats from other food in your shopping cart and in your refrigerator.
- Seal it. Make sure juices from raw meat or poultry do not drip onto other foods. Seal raw foods in containers or plastic bags.
- Take special precaution when using marinades! Sauce which has been used to marinate raw meats should NOT be used on cooked foods unless it is boiled first.
IV: Storing Food Safely
Bacteria grow most rapidly between the temperatures of 40 °F and 140 °F, so it is very important to keep foods out of this temperature range. Cold temperatures keep many harmful bacteria from growing and multiplying, so make sure to promptly refrigerate unused or leftover foods!
Four Golden Rules to Remember
The USDA and the FDA recommend that consumers use the following guidelines to ensure food products are stored at the proper temperatures.
- Always make sure to refrigerate or freeze perishables, prepared foods, and leftovers within two hours of purchase or preparation. If the temperature is above 90 °F, reduce the time frame to 1 hour. When marinating, store the foods in the refrigerator.
- Your refrigerator should be set at 40 °F to discourage the growth of foodborne bacteria. You can use a refrigerator or freezer thermometer to check the temperature of your refrigerator.
- Never place frozen foods on the counter and attempt to defrost food at room temperature. To safely thaw food, place it in the refrigerator the night before. For quick thawing, submerge food in cold water in airtight packaging. You can also use your microwave to thaw food if you will plan to cook it immediately.
- When storing leftover food products, it is important that the temperature of food products be reduced rapidly to discourage bacterial growth. To help reduce temperatures quickly, separate large amounts of leftovers into small, shallow containers, which will allow for quicker cooling of the foods when placed in the refrigerator. Hot food can be placed directly in the refrigerator, but make sure to divide large quantities of food into shallow containers for quicker cooling.
Additional Food Storage Tips
If not properly handled, stored, and prepared, food products can harbor many different organisms that can cause foodborne illnesses. Below are some general tips that consumers should keep in mind when preparing and storing food.
- Canned/Vacuum Packed Foods: Botulism can grow in canned and vacuum-packed foods. If cans or packages are swollen, do not open them. If one end of a can pops when the other end is pushed, or if there are signs of moisture or leakage, do not attempt to use the product.
- Dry Foods: Dry food products include flour, cereal, and sugar. These products should be kept at least six inches off the floor and stored in clean, dry areas. Do not purchase packages that appear to be damaged, i.e. packages with rips, tears, or punctures.
- Fresh Foods: Meats, poultry, seafood, dairy products, egg products, fruits and vegetables requiring refrigeration should be stored at or below 40 degrees Fahrenheit.
- Frozen Foods: Frozen food should be stored at 0 degrees Fahrenheit. Frozen foods should be thawed carefully to avoid spoilage or contamination. They should be thawed either in a refrigerator or as part of the cooking process. Frozen food products should not be thawed at room temperature. Freezing does not kill bacteria.
