Cook: Cook to proper temperatures

Rule 3: Cook, image of a steaming pot and the text: Foods are properly cooked when they are heated for a long enough time and at a high enough temperature to kill the harmful bacteria.

Food safety experts agree that foods are properly cooked when they are heated for a long enough time and at a high enough temperature to kill the harmful bacteria that cause foodborne illness. The best way to Fight BAC!™ is to:

Thermometer Tips

Use a food thermometer to make sure foods have been properly cooked to a safe internal temperature. Plus you won't over cook your food.

There are several types of thermometers available:

  • Dial oven-safe: This type of thermometer is inserted into the food at the beginning of the cooking time and remains in the food throughout cooking.

    By checking the thermometer as the food cooks, you will know exactly when thick cuts of meat, such as roasts or turkeys, are cooked to the correct temperature. This type of thermometer is not appropriate for use with food that is thin, like boneless chicken breast.

  • Dial instant-read: This thermometer is not designed to stay in the food during cooking.

    When you think the food is cooked to the correct temperature, you check it with the instant-read thermometer. To do this, insert the instant-read thermometer into the thickest part of the food. Insert to the point marked on the probe—usually to a depth of 2 inches. About 15 to 20 seconds are required for the temperature to be accurately displayed.

    This type of thermometer can be used with thin food, such as chicken breasts or hamburger patty—simply insert the probe sideways, making sure that the tip of the probe reaches the center of the meat.

  • Digital instant-read: This type of thermometer does not stay in the food during cooking you check the temperature when you think the food is cooked.

    The advantage of this type of thermometer is that the heat-sensing device is in the tip of the probe. Place the tip of the probe in the center of the thickest part of the food—at least 1/2 inch deep. About 10 seconds are required for the temperature to be accurately displayed.

    This type of thermometer is good to use for checking the temperature of a thin food like a hamburger patty. Just insert the probe from the top or sideways to a depth of 1/2 inch.

    (FYI: Pop-up timers are reliable within 1 to 2 degrees, but it's best to check with a food thermometer.)

Rule 4: Chill, image of a refrigerator and the text: Refrigerate foods quickly because cold temperatures keep most harmful bacteria from growing.

Chill: Did You Know?

At room temperature, bacteria in food can double every 20 minutes. The more bacteria there are, the greater the chance you could become sick.

So, refrigerate foods quickly because cold temperatures keep most harmful bacteria from multiplying. A lot of people think it will harm their refrigerator to put hot food inside--it's not true. It won't harm your refrigerator and it will keep your food--and you--safe.

Set your home refrigerator no higher than 40°F and the freezer unit at 0°F. Check the temperature occasionally with an appliance thermometer.

The, Fight BAC!TM by following these steps:

Safe Thawing:

Never thaw foods at room temperature. You can safely thaw food in the refrigerator. Four to five pounds takes 24 hours to thaw.

You can also thaw food outside the refrigerator by immersing in cold water. Change the water every half hour to keep the water cold.

You can thaw food in the microwave, but if you do, be sure to continue cooking right away.

Fresh Produce

  • Raw fruits are safe at room temperature, but after ripening they will mold and rot quickly. For best quality, store ripe fruit in the refrigerator or prepare and freeze. After cooking, fruit must be refrigerated or frozen within 2 hours.

  • Some dense raw vegetables--like potatoes and onions--can be stored at cool room temperatures. Refrigerate other raw vegetables for optimum quality and to prevent rotting. After cooking, vegetables must be refrigerated or frozen within 2 hours.

Special Foods/Special Advice

Some foods may contain bacteria that can be especially harmful to young children and cause serious illness. This section highlights foods preschool children are advised not to eat. It also explains important safe food handling tips for some ready-to-eat foods.

Foods Young Children are Advised Not to Eat

To reduce risks of illness from bacteria in food, young children (and others who face special risks of illness) are advised not to eat:

  • Raw fin fish and shellfish, including oysters, clams, mussels, and scallops.

  • Raw or unpasteurized milk or cheese.

  • Soft cheeses such as feta, Brie, Camembert, blue-veined, and Mexican-style cheese. (Hard cheeses, processed cheeses, cream cheese, cottage cheese, or yogurt need not be avoided.)

  • Raw or lightly cooked egg or egg products including salad dressings, cookie or cake batter, sauces, and beverages such as egg nog. (Foods made from commercially pasteurized eggs are safe to eat.)

  • Raw meat or poultry.

  • Raw sprouts (alfalfa, clover, and radish)

  • Unpasteurized or untreated fruit or vegetable juice (These juices will carry a warning label.)

  • New information on food safety is constantly emerging. Recommendations and precautions are updated as scientists learn more about preventing foodborne illness. You need to be aware of and follow the most current information on food safety. See page 17 for ways to learn about food safety updates.

Reheating ready-to-eat foods:

It's important to reheat some foods that you buy pre-cooked. That's because these foods can become re-contaminated with bacteria after they have been processed and packaged at the plant.

These foods include: hot dogs, luncheon meats, cold cuts, fermented and dry sausage, and other deli-style meat and poultry products.

Eating Out, Bringing In

Let's face it. Sometimes it's just easier and more enjoyable to let someone else do the cooking. And for today's families there are many eating options. All of these options, however, do have food safety implications that you need to be aware of.

Image of take out food and the text: Hot or cold ready-prepared meals are perishable and can cause illness when mishandled.

Bringing In: Complete Meals to Go and Home Delivered Meals

When you want to eat at home but don't feel like cooking or aren't able to, where do you turn?

Hot or cold ready-prepared meals are perishable and can cause illness when mishandled. Proper handling is essential to ensure the food is safe.

The 2-Hour Rule

Harmful bacteria can multiply in the "danger zone" (between 40 and 140 degrees F). So remember the 2-hour rule. Discard any perishable foods left at room temperature longer than 2 hours.

(When temperatures are above 90°F, discard food after 1 hour!)

Putting the 2-hour rule into action:

Image of a thermometer and the temperature various foods should be heated to prevent harmful bacteria. Harmful bacteria can grow rapidly in the danger zone (between 40 degrees and 140 degrees).

HOT FOODS: When you purchase hot cooked food, keep it hot. Eat and enjoy your food with 2 hours to prevent harmful bacteria from multiplying

If you are not eating within 2 hours—and you want to keep your food hot—keep your food in the oven set at a high enough temperature to keep the food at or above 140 degrees F. (Use a food thermometer to check the temperature.) Side dishes, like stuffing, must also stay hot in the oven. Covering food will help keep it moist.

However, your cooked food will taste better if you don't try to keep it in the oven for too long. For best taste, refrigerate the food and then reheat when you are ready to eat. Here's how:

COLD FOODS should be eaten within 2 hours or refrigerated or frozen for eating another time.

Reheating?

You may wish to reheat your meal, whether it was purchased hot and then refrigerated or purchased cold initially.

All food service establishments are required to follow food safety guidelines set by State and local health officials.

Eating Out

Whether you're eating out at a restaurant or a fast food diner, it can be both a safe and enjoyable experience. All food service establishments are required to follow food safety guidelines set by State and local health departments. But you can also take actions to insure your food's safety. Keep these Fight BAC!™ rules in mind: Clean, Cook, Chill.

Clean: When you go out to eat, look at how clean things are before you even sit down. If it's not up to your standards, you might want to eat somewhere else.

Cook: No matter where you eat out, always order your food cooked thoroughly to a safe internal temperature. Remember that foods like meat, poultry, fish, and eggs need to be cooked thoroughly to kill harmful bacteria. When you're served a hot meal, make sure it's served to you piping hot and thoroughly cooked, and if it's not, send it back.

Don't eat undercooked or raw foods, such as raw oysters or raw or undercooked eggs. Undercooked or raw eggs can be a hidden hazard in some foods like Caesar salad, custards and some sauces. If these foods are made with commercially pasteurized eggs, however, they are safe. If you are unsure about the ingredients in a particular dish, ask before ordering it.

Chill

The Doggie Bag

It seems like meal portions are getting bigger and bigger these days. A lot of people are packing up these leftovers to eat later. Care must be taken when handling these leftovers. If you will not be arriving home within 2 hours of being served, it is safer to leave the leftovers at the restaurant.

Also, remember that the inside of a car can get very warm. Bacteria may grow rapidly, so it is always safer to go directly home after eating and put your leftovers in the refrigerator.

Those are the food safety rules—the way you can help yourself and others Fight BAC!™

Just remember: an ounce of prevention is worth a pound of cure.
