Why Food Safety Matters at Community Suppers

Safe food-handling practices help prevent foodborne illness during large group meals and events.

Community suppers are gatherings where groups of people with common interests can socialize, network, celebrate, or work while sharing a meal. These events are fun and productive, but can quickly become disastrous when basic food safety practices are not followed.

Foodborne illness occurs when pathogens are transmitted through food and can sicken many people in a group setting.

Most healthy adults tolerate foodborne pathogens without significant illness. However, infants, the elderly and people with compromised immune systems can experience serious complications and even death.

Most cases can be prevented by proper food handling.

During the planning stage of a community supper, organizers should designate a reliable person responsible for food safety. The designated person should be up to date on current food handling practices.

The following basic food safety guidelines provide detailed information on maintaining cleanliness, controlling the time and temperature at which food is held, and avoiding the transfer of harmful bacteria to food (cross-contamination). These guidelines should be strictly adhered to when coordinating and preparing food for a community supper.

How to Keep Food Safe Through Proper Cleanliness

Food can be contaminated by coughs and sneezes, handling, dirty equipment, vermin, animals, and waste. It should be protected during storage, preparation, display, and service.

Clean Hands for Safe Food Handling

Everyone involved in food service should keep their hands extra clean at all times.

Effective hand washing requires thorough cleaning of hands and fingernails with soap and water:

  • before working with foods
  • after using the toilet
  • every time hands are soiled

Hands can easily become a vehicle for foodborne pathogens through seemingly innocent acts like scratching the scalp, running fingers through hair or touching a pimple.

To properly wash hands:

  1. Wet hands with warm water.
  2. Generously apply soap.
  3. Rub hands vigorously for at least 20 seconds.
  4. Scrub under nails with a clean nailbrush.
  5. Rinse hands under clean, warm, running water.
  6. Dry hands using a clean paper towel.

Healthy Workers and Safe Food Preparation

Diseases can be passed from person to person through food.

People with the following conditions should not handle food:

  • open wounds
  • sore throat with fever
  • diarrhea,
  • eye infections
  • or ear infections

Those involved in food service should wear:

  • clean clothing (including aprons or smocks)
  • closed-toe leather shoes (no sandals or canvas tennis shoes)
  • hair covering to restrain hair

Workers who touch food during preparation should wear clean, single-use plastic gloves (or food-grade plastic bags) over their hands.

Sanitized Utensils and Clean Serving Dishes

Dirty utensils can spread pathogens during food preparation and service.

Don’t use the same serving utensil for more than one dish; use a separate utensil for each dish to prevent the spread of pathogens.

When cleaning utensils:

  1. Scrape away food debris and soak utensils if necessary.
  2. Wash in hot, soapy water.
  3. Rinse.
  4. Sanitize utensils in hot water (140°F) with ½ tablespoon of chlorine bleach per 1 gallon of water.

Keep forks, knives, paper plates, and cups clean, and store them in a location where they will remain clean. Handle carefully during serving.

How to Control Food Temperatures at Community Suppers

Controlling food temperature is one of the most important ways to prevent foodborne illness at community suppers.

Food is safest immediately after it is prepared. The longer it is held (hot or cold), the greater the chance that it will become unsafe. Monitoring the time food spends at temperatures between 40 °F and 140 °F is critical to safety.

The temperature range of 40°F to 140°F is known as the “danger zone” because bacteria grow rapidly in this range.

Bacteria grow best in lukewarm foods, so hot foods should be kept hot (140°F or higher) for no longer than two hours, and cold foods should be kept cold (40°F or lower).

Perishable food is safe when it is stored at the correct temperature, cooked to the correct minimum internal temperature, and served/held at the correct holding temperature.

It is temperature abused when it is allowed to stay in the danger zone for more than two hours.

For example, if it takes two hours to make a chicken salad, it is refrigerated overnight, and the next day, it is left on the buffet table for two hours, the total time at room temperature is four hours.

Food contaminated and left at room temperature for four hours can cause illness.

Storing food in the refrigerator slows pathogen growth but does not stop it.

Hot and cold holding systems present special problems in food handling.

Foodborne illnesses in community settings can be caused by improper holding temperatures for hazardous foods or by preparing foods too long before they are eaten.

A knowledgeable food-service worker should supervise hot- and cold-holding systems for buffets or dinners. At the very least, ask an adult to accept responsibility for monitoring the temperatures in the food-holding units.

Temperatures must be monitored during preparation, storage and service. Measure food temperature at regular intervals with a metal-stem thermometer and sanitize the stem between uses.

The most perishable foods contain meat, poultry, seafood, eggs or milk.

Hot Food Safety Tips for Community Suppers

Keep hot foods at 140°F or higher whenever possible.

Keep protein foods such as seafood, poultry and cooked meats hot by using an electric hot tray or chafing dish. Small candle-warming units may not keep food hot enough.

  • Do not let hot food stand at room temperature for more than two hours (including preparation, storage and serving time).
  • Do not prepare food more than four hours before serving it. Prepare potentially hazardous foods no more than three hours before serving.
  • When using a hot-holding table, be sure the food temperature is above 140°F. Casseroles, gravies, and meats are safest when maintained at 165°F or above.
  • Cover pans containing hot food so that heat does not escape rapidly.

Safe Cold Holding Temperatures for Community Suppers

Many dishes should be held at temperatures below 40°F, including:

  • Meats
  • Poultry
  • Seafood
  • Eggs
  • Cream pies
  • Puddings
  • Seafood salads

Holding them below 40°F will prevent potentially harmful bacteria from reaching dangerous levels.

When handling cold foods, never let them stand at room temperature for more than two hours, including preparation, storage, and serving time.

Do not thaw meat on the counter or hold casseroles at room temperature before baking.

Room Temperature Foods That Are Safer Choices

Shelf-stable foods that are safer at room temperature include:

  • Dry foods (breads, granola and crackers)
  • Jams
  • Jellies
  • Pickles that are “preserved” with sugar, salt, or vinegar

If hot and cold storage facilities are unavailable or inadequate, the safest choices are foods that are stable at room temperature.

Foods That Are Sometimes Problematic at Potlucks and Community Suppers

Some foods require extra caution because bacteria can grow quickly if they are improperly stored or handled.

Foods that can present food safety problems include:

  • Cooked or cut-up raw fruits and vegetables
  • Processed meats
  • Cooked vegetables
  • Fruit salads
  • Green salads
  • Luncheon meats
  • Hot dogs
  • Cheeses

Potentially Hazardous Foods at Community Suppers

Meat-based and cooked-starch foods that are potentially hazardous include:

  • Meats
  • Potatoes
  • Potato-containing foods
  • Cooked rice
  • Custards
  • Puddings
  • Pies
  • Gravies
  • Bread stuffing
  • Beans
  • Salads containing meat
  • Starchy foods
  • Whipped cream
  • Desserts that contain milk or egg

Safe Cooking Practices for Community Suppers

Cooking Temperatures for Large Group Meals

Cooking food to a specified minimum temperature is required to destroy harmful germs.

Use a food thermometer to ensure that all parts of cooked food reach a safe internal temperature. Cooking “by the clock” is not a reliable safety measure.

Other safe temperature guidelines include:

Avoid Unsafe Slow Cooking Practices

No slow cooking at low temperatures. If cooking takes six hours or more, or the cooking temperature is below 300 °F, microorganisms may grow during the early cooking period.

Avoid Partially Cooking Foods

No partial cooking of foods. Do not partially cook and then hold food before final cooking.

Use Constant Heat Sources During Cooking

Cook with a constant heat source. For example, do not preheat the oven to 450 ºF, put a casserole in to bake, then turn the oven off and let the casserole stand in the oven for an hour.

USDA-Recommended Minimum Internal Temperatures for Common Community Dinner Dishes

The USDA recommended minimum internal temperatures for common community dinners are as follows:

Minimum Temperature

Foods

145°F Beef; lamb; pork and veal steaks; roasts and chops (medium-rare; plus 3-minute rest time*); fish and shellfish
160°F Egg dishes; ground beef, veal, pork, or lamb
165°F Leftovers; poultry; stuffing and casseroles

*After removing meat from a grill, oven, or other heat source, allow it to rest for the specified amount of time. During the rest time, its temperature remains constant or continues to rise, which destroys harmful germs.

How to Safely Handle Take-Out Foods for Community Suppers

Sometimes people will bring take-out food to a community supper. The same basic food safety rules apply to prepared foods purchased from a deli or restaurant.

Take-Out Food Safety Tips

  • Do not leave take-out food at room temperature longer than two hours.
  • Refrigerate cold foods at 40°F or lower until serving time.
  • If the food is hot and will not be eaten within two hours, keep it hot (140°F) in a 200°F to 250°F oven.
  • When picking up hot foods far in advance, refrigerate them.
  • “Thick foods” such as stews and layers of meat should be refrigerated in shallow dishes to cool faster.

Leftover Food Safety Tips After Community Suppers

  • Divide large amounts of hot leftovers into small, shallow containers for quick cooling, then place them directly in the refrigerator or freezer. Discard food that has been left standing at room temperature for more than two hours.
  • The center of hot foods that are cooling should reach a temperature of 45°F within four hours to prevent the growth of pathogens.
  • Cool food in containers with loose covers. Tight covers prevent air from circulating the food, slowing cooling.
  • Place containers of hot food in the refrigerator side by side with air space in between.
  • Refrigerator temperature should be set and maintained between 34°F and 40°F.
  • Date leftovers so they can be used within a safe time. Most foods remain safe when refrigerated for three to five days, although ground meats and meat gravies should be kept only for one to two days.

If in doubt, throw it out. Never taste food that looks or smells strange. Even a small amount of contaminated food can cause illness.

How to Prevent Cross-Contamination at Community Suppers

Preventing cross-contamination is one of the most important steps in avoiding foodborne illness.

Cross-contamination occurs when bacteria spread from one food to another. This can create an unsafe situation when bacteria are transferred to a food that will not be cooked, leaving no opportunity to destroy them. In these cases, harmful bacteria may multiply to dangerous levels.

Cross-contamination can be avoided by following these rules:

Keep Raw and Cooked Foods Separate

Keep cooked foods separate from raw foods.

Thaw and store meat and poultry in a pan or tray with a lip to prevent juices from dripping onto other foods and surfaces.

Sanitize Counters and Utensils Properly

Wash and sanitize equipment, utensils, countertops, surfaces and hands that have touched raw foods before allowing them to come into contact with finished foods.

Wash and sanitize counters and utensils every two hours when food is being prepared.

To sanitize utensils, immerse them in water containing ½ tablespoon of chlorine bleach per 1 gallon of warm water for at least 1 minute.

Utensils can be hot sanitized by immersing them in water at 170°F for at least 30 seconds. Rinse cycles in dishwashers should be 180°F.

Sanitize counters by washing them with a solution of 1 tablespoon chlorine bleach per 1 gallon of warm water.

Safe Beverage Handling for Community Suppers

Prepare, store, and serve acidic beverages, such as fruit juice or punch, in containers made from:

Safe Beverage Containers

  • Food-grade plastic
  • Stainless steel
  • Glass

Avoid Using

  • Porcelain
  • Enamelware
  • Metals other than stainless steel

Food Safety Regulations for Potlucks, Community Suppers, and Bake Sales

Churches, schools, and other groups qualify as food-service establishments when they offer individual portions of food for sale at bazaars and bake sales.

Organizations planning a food-related activity should contact the local public health department. The health department can inspect the facilities. They can also advise on the types of food that can be prepared safely and on regulations that may apply to the event.

South Carolina has special rules for non-profit bake sales and bazaars. Non-profit organizations are often allowed to sell some food items without a permit.
