Bacteria can be spread throughout the kitchen and get onto hands, cutting boards, utensils, counter tops, and food.
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.
Food is safely cooked when it reaches a high enough internal temperature to kill the harmful bacteria that cause foodborne illness. Use a food thermometer to measure the internal temperature of cooked foods.
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 40°F 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 40°F or below. The freezer temperature should be 0°F or below.
Prepare cooked food, such as turkey, ham, chicken, and vegetables or pasta salads, ahead of time to allow for thorough chilling in the refrigerator. Divide large amounts of food into shallow containers for fast chilling and easier use. Keep cooked food refrigerated until time to leave home.
To keep lunches cold away from home, include a small frozen gel pack or frozen juice box. Of course, if there’s a refrigerator available, store perishable items there upon arrival. Insulated, soft-sided boxes or bags are best for keeping food cold, but metal or plastic lunch boxes and paper bags can also be used. If using paper lunch bags, create layers by double bagging to help insulate food.
Some food is safe without a cold source. Items that don’t require refrigeration include whole fruits and vegetables, hard cheese, unopened canned meat and fish, chips, breads, crackers, peanut butter, jelly, mustard, and pickles.
Use an insulated container to keep food like soup, chili, and stew hot. Fill the container with boiling water, let stand for a few minutes, empty, then put in the piping hot food. Keep the insulated container closed until lunchtime to keep the food hot—140°F or above.
For more information, visit the USDA Food Safety and Inspection Service (FSIS).
These short but safe time limits for home-refrigerated foods will keep them from spoiling or becoming dangerous to eat. The guidelines for freezer storage are for quality only. Frozen foods remain safe indefinitely.

As a general rule, use refrigerated leftovers within four days for best safety and quality. Freeze for longer storage. Cool foods in the refrigerator before putting them in your freezer.
Sometimes you will see these foods in commercially frozen products because food companies have equipment that freezes food faster and helps retain quality better. Also, various ingredient, generally unavailable to home cooks, are used commercially to help prevent frozen foods from breaking down.
Before you double a recipe for frozen leftovers, experiment by freezing a small amount the next time you make the recipe. If you’re satisfied with the results, prepare extra food for freezing when you make the recipe again.
As a general rule, foods with high water content, such as the vegetables in our list, do not freeze well. The water in food expands during freezing and breaks down the food’s structure, making the food mushy when thawed. This is why frozen fruit packages often advise eating the fruit while still slightly frozen.
Freezing Wrapping Materials
Freezer containers
DO NOT thaw perishable foods at room temperature. Just ONE bacterium, doubling every 20 minutes, could grow to 64 bacteria in two hours, and 2,097,152 bacteria in seven hours!
If perishable foods, such as meat, are left at room temperature too long, bacteria may grow and produce heat-resistant toxins that can cause food-borne illness. Cooking may not be able to destroy these toxins.
If thawing in a plastic freezer bag in the microwave, follow manufacturer’s directions for such things as venting, recommended heat settings, types of food suitable for microwave-thawing, etc. for that specific bag.
Follow microwave manufacturer’s directions for your specific microwave.

Freezing is a great way to keep fresh vegetables tasty and nutritious for a longer time than keeping them in the refrigerator or on the counter top.
Freezing doesn’t sterilize the vegetables, but the cold temperatures slow down the growth of bacteria. And the processes that cause vegetables to rot and spoil slow down, too.
Start with high-quality fresh vegetables. And freeze them soon after you get them.
Handle them carefully, to keep them from getting bruised or damaged before you freeze them.
Choose containers that are intended to be used in the freezer. They should be moisture- and vapor-resistant. They should be durable and not become brittle in the freezer. And they should be easy to seal securely.
Good containers include plastic freezer containers, flexible freezer bags, or wide-mouth glass canning jars.
Don’t use the plastic containers that yogurt, tub margarine, or cottage cheese come in. And don’t use cardboard milk cartons or ice cream containers. And regular jars, like the ones jelly or mayonnaise come in, are made of thin glass that is likely to break when it is frozen.
Use the freshest, highest-quality vegetables you can find.
If you are picking them from your garden, pick them early in the morning, when it is still cool. Freeze them within a few hours after picking them.
Wash the vegetables well in cold water. Let the water run over them to wash away any dirt. If you are washing them in a sink or tub full of water, lift the vegetables out of the water and let the dirt settle to the bottom.
Sort the vegetables according to size. It will be easier to pack vegetables of similar size into the same container.
Blanching means that you put the vegetables into boiling water for a short time before you put them in the freezer containers. For some vegetables, steaming is a better way to blanch.
Blanching is an important step for many reasons:
The amount of time you leave the vegetables in the boiling water is extremely important. The time varies according to the size of the vegetables and from one kind of vegetable to another.
Blanching for too short a time stimulates the enzymes that cause spoiling and is worse than not blanching at all.
Blanching for too long a time makes the vegetables lose flavor, color, and vitamins.

Food dating stamps, like the Nutrition Facts label, give you good information about the food you buy. They can tell you when to keep a food and eat it, and when you should throw it out! You just need to know what the different stamps mean to keep your food safe to eat and tasting good, too.
Most of the dates you see on food are for quality, not food safety. Foods are often safe to eat past the date on the label, as long as there are no visible signs that the food is spoiled.
This is last date recommended for use of the food. For the best taste and texture, use the food before the date has passed. It is not a safety date, except when used for baby formula.
Generally, throw away any food that is past the Use-By date. Some canned foods may still be good, but, when you open the can, if the color, texture, or odor of the food isn’t right, throw it out!
“Exp” stands for “Expiration” date. For the best taste and texture, use the food before the date has passed.
Generally, throw away any food that is past the Expiration date. The exception is eggs. If they have been kept in the refrigerator, eggs can still be used 3 to 5 weeks after the Expiration date.
This date tells the store how long to keep the food on the shelf for sale. It is not a safety date.
Use before or shortly after the date has passed. Sometimes, grocery stores will have sales on foods that are close to their Sell-By date. You can get a good bargain, but be sure to use it soon!
Do not buy foods that are past their Sell-By date.
For the best taste and texture, use before or shortly after the date has passed. This is not a purchase or safety date.
Throw away any foods that are more than a few days past the date. If the foods have not been stored properly, throw them out earlier.
For baby formula or pre-packaged, washed produce (like bags of salad), throw it away immediately when the date has passed. No exceptions!

Keeping food safe for your children helps keep them healthy. Good habits about food safety will last a lifetime!
Teach your children to wash their hands before and after eating, after using the bathroom, after playing with pets, and whenever their hands are dirty.
Keep a stool by the sink to help small children reach it more easily.
Sing the Alphabet Song or “Happy Birthday to You” or “Twinkle, Twinkle, Little Star” while hand washing. This will help you make sure that the children wash their hands for at least 20 seconds each time.
Let your children pick out a favorite soap that they will have fun using.
Children who wash their hands often are less likely to get sick.
Small children get sick more easily because their immune systems are not fully developed. Keep food and the counter tops and table tops clean.
Wash surfaces and utensils before and after you prepare meals or snacks for your children.
Don’t choose foods that are hard to swallow. Or cut them into pieces 1/2 inch or smaller. These foods include peanuts, popcorn, hot dog slices, hard candy, whole grapes, and cherry tomatoes.
Make sure your children sit down when they are eating. Don’t let them run, walk, play, or lie down while they have food in their mouths.
Keep cold foods cold by adding a frozen juice box, water bottle, or small ice pack to an insulated lunch bag. If you are using paper lunch sacks, double them up to help keep things cold. By lunch time, the juice box or water bottle will have thawed enough to drink!
Keep hot foods hot in an insulated thermos. Be sure to prime the thermos first, by filling it with boiling water. Let it stand for a few minutes, then pour the water out. Fill the thermos with piping hot soup or stew!
If snacks come in a large box or bag, divide them up right away into small, single-serving bags. Many hands digging into the big box can spread germs to all the snacks inside.
Rinse fruits and vegetables before slicing them to serve as snacks.
Hard-cooked eggs can be an easy and nutritious food for small children.
Before cooking, always keep the eggs in the refrigerator. After cooking, return them to the refrigerator within 2 hours.
If you are dyeing the eggs for the holidays, be sure to use food-safe coloring.
The fats in fish and shellfish are good for young children, and adults, too! But some fish can also contain high levels of mercury and other toxic chemicals. Fish that are usually lower in mercury are catfish, pollock, salmon, sardines, tilapia, and trout
Outdoor barbecues and picnics are a great way to connect with family and friends. However, careless food handling could cause foodborne illness and quickly make you an unpopular host. Taking just a few simple steps can greatly reduce the risk of sickness. These tips will help ensure that your food stays safe and your guests stay healthy.
Just like humans, bacteria thrive in temperatures that are not too hot or too cold. The “danger zone” is 40 to 140 degrees Fahrenheit. Dangerous bacteria are more likely to grow in this temperature range. Keep cold foods below 40° F and hot foods above 140° F.
Frozen meat should never be thawed at room temperature. Instead, thaw in the refrigerator ahead of time. If it’s last minute, submerge sealed packages in cold (not warm or hot) water, or thaw in the microwave. Thoroughly cook foods immediately after microwave thawing.
Marinating meat can improve tenderness, juiciness, and flavor. Always marinate food in the refrigerator, not on the countertop. If you plan to use the marinade as a baste during grilling, reserve some for basting before you put the raw meat in it. Discard marinade as soon as you take the meat out of it.
Precooked meats such as hot dogs, smoked sausages, chicken breasts, or burgers are great options that are available at many retail stores. Simply follow the package instructions for reheating on the grill. If you precook foods yourself, make sure they go immediately on the grill; don’t hold them at room temperature before putting on the grill.
When picnicking or tailgating away from home, use a cooler to store anything that was refrigerated. Fill it just before leaving home, add plenty of ice, and don’t open the cooler repeatedly; it makes the ice melt faster. Consider having a separate tub or cooler for drinks to avoid repeatedly opening the cooler with perishable foods. Always separate raw meat from ready-to-eat foods like salads and desserts. Try to keep the cooler in a shaded area to maintain temperature more efficiently.
Digital food thermometers can be purchased for around $10, and they’re easy to use and read. Consider them an easy and inexpensive way to both prevent foodborne illness and make sure you don’t overcook your steaks. The thermometer should be placed in the center of the food, not touching bones or big pieces of fat or gristle. Use the cooking temperatures chart to determine when different meat products are safe.
Keep cold foods cold by placing the bowl of food inside of a slightly larger bowl filled with ice. Keep hot foods hot on the grill (not directly over the coals) and with crock pots, chafing dishes, or “beer baths.” To make a beer bath, fill a pan with beer, juice, broth, or other liquid, and place it on the grill; after cooking burgers, chicken, or brats, place them in the hot liquid to keep the food hot and add extra flavor.
A general rule of thumb is never to leave perishable items out of the refrigerator for more than 2 hours, or for more than 1 hour when the outside temperature is above 90°F. Here in Mississippi, the summer temperature can soar above 90°F for weeks on end. It’s important to make sure food is not left out more than an hour on these hot days. The food will not only be safer, but it will also look better and taste fresher. In hotter months, consider holding your gathering in the evening hours, when temperatures cool off and your guests may be more comfortable. Also consider adding nonperishable items to your picnic. Whole fruits like grapes, apples, bananas, oranges, peaches, and cherry tomatoes, along with crackers, pretzels, nuts, chips, breads, and cookies can be added to the menu and don’t have to take up valuable cooler space. However, cut or pre-peeled fruits and vegetables should always be kept cool, and you should follow the same handling guidelines for other refrigerated items.
Put food in the refrigerator, freezer, or cooler within 2 hours if the temperature outside is less than 90°F, or within 1 hour if the temperature is above 90°F. If foods stay out for too long, or if you are unsure whether or not they are safe, discard them. Reheat leftovers to 165°F.
Never put cooked meat or other foods on the same plate that held raw meat. That raw meat juice contains bacteria that will recontaminate your food. Don’t want to wash double dishes? Use disposables for raw and cooked foods. Always wash your hands after handling raw meat and before you touch cooked meat.
If you are away from home, make sure you have a potable water source for cleanup, or bring containers from home if necessary. Supplement water with antibacterial wipes for cleaning tables and other surfaces, and consider using disposable containers and utensils, especially for raw items.
