Food Safety & Storage

Food safety education offered by Cornell Cooperative Extension targets both consumers and food service professionals. Our outreach to consumers, who are concerned primarily with food safety in the home, includes newspaper and newsletter articles, answering consumers questions by phone, public presentations, and distribution of information at public events and gatherings.

Four Simple Steps to Food Safety

Foodborne illness can strike anyone. Some people are at a higher risk for developing foodborne illness, including pregnant women, young children, older adults and people with weakened immune systems. For these people the following four simple steps are critically important:

1. CLEAN: Wash hands and surfaces often

Bacteria can be spread throughout the kitchen and get onto hands, cutting boards, utensils, counter tops and food. To prevent foodborne illness, always:

• Wash your hands with warm water and soap for at least 20 seconds before and after handling food and after using the bathroom, changing diapers and handling pets.
• Wash your cutting boards, dishes, utensils and counter tops with hot soapy water after preparing each food item and before you go on to the next food.
• Consider using paper towels to clean up kitchen surfaces. If you use cloth towels wash them often in the hot cycle of your washing machine.
• Rinse fresh fruits and vegetables under running tap water, including those with skins and rinds that are not eaten.
• Rub firm-skin fruits and vegetables under running tap water or scrub with a clean vegetable brush while rinsing with running tap water.

2. SEPARATE: Don’t cross-contaminate

Cross-contamination is how bacteria can be spread. When handling raw meat, poultry, seafood and eggs, keep these foods and their juices away from ready-to-eat foods. Always start with a clean scene— wash hands with warm water and soap. Wash cutting boards, dishes, countertops and utensils with hot soapy water.

• Separate raw meat, poultry, seafood and eggs from other foods in your grocery shopping cart, grocery bags and in your refrigerator.
• Use one cutting board for fresh produce and a separate one for raw meat, poultry and seafood.
• Never place cooked food on a plate that previously held raw meat, poultry, seafood or eggs.

3. COOK: Cook to proper temperatures

Food is safely cooked when it reaches a high enough internal temperature to kill the harmful bacteria that cause illness. Refer to the chart for the proper internal temperatures.

• Use a food thermometer to measure the internal temperature of cooked foods. Make sure that meat, poultry, egg dishes, casseroles and other foods are cooked to the right internal temperature. Color is not a reliable indicator of doneness.
• Cook eggs until the yolk and white are firm. Only use recipes in which eggs are cooked or heated thoroughly.
• When cooking in a microwave oven, cover food, stir and rotate for even cooking. Food is done when it reaches the correct internal temperature.
• Bring sauces, soups and gravy to a boil when reheating.

4. CHILL: Refrigerate promptly

Refrigerate foods quickly because cold temperatures slow the growth of harmful bacteria. Do not over-stuff the refrigerator. Cold air must circulate to help keep food safe. Keeping a constant refrigerator temperature of 40ºF or below is one of the most effective ways to reduce the risk of foodborne illness. Use an appliance thermometer to be sure the temperature is consistently 40ºF or below. The freezer temperature should be 0ºF or below.

• Refrigerate or freeze meat, poultry, eggs and other perishables as soon as you get them home from the store.
• Never let raw meat, poultry, eggs, cooked food or cut fresh fruits or vegetables sit at room temperature more than two hours before putting them in the refrigerator or freezer (one hour when the temperature is above 90ºF).
• Never defrost food at room temperature. Food must be kept at a safe temperature during thawing. There are three safe ways to defrost food: in the refrigerator, in cold water, and in the microwave. Food thawed in cold water or in the microwave should be cooked immediately.
• Always marinate food in the refrigerator.
• Divide large amounts of leftovers into shallow containers for quicker cooling in the refrigerator.
• Use or discard refrigerated food on a regular basis. Check USDA cold storage information for optimum storage times.
