How could eggs become contaminated?

1. Salmonella: Salmonella is a type of bacteria that can cause food poisoning. Eggs can become contaminated with Salmonella if they come into contact with feces from infected animals, such as chickens. Salmonella can also contaminate eggs if they are not properly cooked.

2. E. coli: E. coli is another type of bacteria that can cause food poisoning. Eggs can become contaminated with E. coli if they come into contact with raw meat or poultry, or if they are not properly cooked.

3. Campylobacter: Campylobacter is a type of bacteria that can cause diarrhea, abdominal pain, and fever. Eggs can become contaminated with Campylobacter if they come into contact with raw poultry or if they are not properly cooked.

4. Listeria: Listeria is a type of bacteria that can cause serious illness, especially in pregnant women and people with weakened immune systems. Eggs can become contaminated with Listeria if they come into contact with contaminated food or if they are not properly refrigerated.

5. Environmental contamination: Eggs can also become contaminated with harmful substances from the environment, such as pesticides, heavy metals, and dioxins. This can occur if eggs are laid in areas that are contaminated with these substances, or if they are processed in unsanitary conditions.

To reduce the risk of contamination, it is important to:

* Buy eggs from reputable sources.

* Refrigerate eggs at or below 40°F (4°C).

* Cook eggs thoroughly until the yolk is firm.

* Avoid eating raw or undercooked eggs.

* Wash your hands after handling raw eggs.
