This information is based upon written articles from the United States Food and Drug Administration Website. This is about Egg Safety: What You Should Know.
Fresh eggs, even those with clean, uncracked shells, may contain bacteria called Salmonella that can cause food-borne illness, often called “food poisoning.” FDA has put regulations in place to help prevent contamination of eggs on the farm and during shipping and storage, but consumers also play a key role in Egg Safety by preventing illness linked to eggs. Protect yourself and your family by following these safe handling tips when buying, storing, preparing, and serving eggs—or foods that contain them.
What is Salmonella?
Salmonella, the name of a group of bacteria, is a common cause of food poisoning in the United States. Most people infected with Salmonella develop diarrhea, fever, abdominal cramps, and vomiting 12 to 72 hours after infection. Symptoms usually last 4 to 7 days and most people get better without treatment. However, in some people, the diarrhea may be so severe that they need to be hospitalized.
In these patients, the Salmonella infection may spread from the intestines to the blood stream, and then to other body sites and can cause death unless the person is treated quickly with antibiotics. Certain people are at greater risk for severe illness and include children, older adults, pregnant women, and people with weakened immune systems (such as transplant patients and individuals with HIV/AIDS, cancer, and diabetes).
The US Food and Drug Administration, in an effort to maintain Egg Safety requires all cartons of shell eggs that have not been treated to destroy Salmonella to carry this safe handling statement:
Safe Handling Instructions
To prevent illness from bacteria: keep eggs refrigerated, cook eggs until yolks are firm, and cook foods containing eggs thoroughly.
Eggs that have been treated to destroy Salmonella–by in-shell pasteurization, for example–are not required to carry safe handling instructions, but the labeling will usually say that they have been treated.
Buying
You can help keep eggs safe by making wise buying decisions at the grocery store.
- Buy eggs only if sold from a refrigerator or refrigerated case.
- Open the carton and make sure that the eggs are clean and the shells are not cracked.
- Store promptly in a clean refrigerator at a temperature of 40° F/5° Centigrade or below. Use a refrigerator thermometer to check.
- Store eggs in their original carton and use them within 3 weeks for best quality.
Storing for Egg Safety
Proper storage of eggs can affect both quality and safety.
- Use hard-cooked eggs (in the shell or peeled) within 1 week after cooking.
- Use frozen eggs within 1 year. Eggs should not be frozen in their shells. To freeze whole eggs, beat yolks and whites together. Egg whites can also be frozen by themselves.
- Refrigerate leftover cooked egg dishes and use within 3 to 4 days. When refrigerating a large amount of a hot egg-containing leftover, divide it into several shallow containers so it will cool quickly.
- Are you going to store raw eggs in the refrigerator?
Eggs should not be stored on the refrigerator door, but in the main body of the refrigerator to ensure that they keep a consistent and cool temperature. Leftover raw egg whites and yolks should be put in airtight containers and stored in the refrigerator immediately. Even better, cook the eggs, put them in an airtight container and into the refrigerator. That is the safest way to handle them.
Preparing
Wash hands, utensils, equipment, and work surfaces with hot, soapy water before and after they come in contact with raw eggs and raw egg-containing foods.
- Cook eggs until both the yolk and the white are firm. Scrambled eggs should not be runny.
- Casseroles and other dishes containing eggs should be cooked to 160° F. Use a food thermometer to be sure.
- For recipes that call for eggs that are raw or undercooked when the dish is served — like Mayonnaise, Caesar salad dressing and homemade ice cream — use either shell eggs that have been treated to destroy Salmonella, by pasteurization or another approved method, or pasteurized egg products.
Serving
Follow these serving guidelines for eggs and egg dishes.
- Serve cooked eggs (such as hard-boiled eggs and fried eggs) and egg-containing foods (such as such as quiches and soufflés) immediately after cooking. Cooked eggs and egg dishes may be refrigerated for serving later but should be thoroughly reheated to 165° F before serving.
- Never leave cooked eggs or egg dishes out of the refrigerator for more than 2 hours or for more than 1 hour when temperatures are above 90° F. Bacteria that can cause illness grow quickly at warm temperatures (between 40° F and 140° F).
- For party planning, keep hot egg dishes hot and cold egg dishes cold:
- Keep egg dishes refrigerated until time to serve.
- Serve small platters of reheated egg dishes at a time to ensure the food stays at the proper temperature. Replenish as needed, or at least every 2 hours.
- Keep cold egg dishes on ice if they are going to stay out longer than 2 hours.
Transporting
- For picnics, pack cooked eggs and egg dishes in an insulated cooler with enough ice or frozen gel packs to keep them cold. Transport the cooler in the passenger compartment of the car, not in the much warmer trunk. At the picnic area, put the cooler in the shade if possible and keep the lid closed as much as you can.
- For school or work, pack cooked eggs with a small frozen gel pack or a frozen juice box.
About Food-borne Illness
Know the Symptoms
Consuming dangerous food-borne bacteria will usually cause illness within 1 to 3 days of eating the contaminated food. However, sickness can also occur within 20 minutes or up to 6 weeks later. Although most people will recover from a food-borne illness within a short period of time, some can develop chronic, severe, or even life-threatening health problems. Food-borne illness can sometimes be confused with other illnesses that have similar symptoms. The symptoms of food-borne illness can include:
- Vomiting, diarrhea, and abdominal pain
- Flu-like symptoms, such as fever, headache, and body ache
Take Action
If you think that you or a family member has a food-borne illness, contact your healthcare provider immediately. Also, report the suspected food-borne illness to your local government’s health department. If you live where people know little or nothing about Egg handling safety, tell egg sellers what you have learned and advise them to keep eggs and foods made with raw egg in refrigeration. If they ignore your advice, shop elsewhere!
