Investigate three common food poisoning bacteria and further explain how each contaminates food

Here are the three most common food poisoning bacterias:

1. Salmonella is the second most common cause of food poisoning. It can be found in unpasteurized milk, eggs, and raw meat, and poultry. Fortunately, salmonella is killed when the food is cooked thoroughly. If a small number of bacteria are present in food, they will multiply unless it is chilled.

2. Listeria usually causes serious illness or even life-threatening in vulnerable groups such as pregnant women, babies, the elderly and people with reduced immunity. This bacteria can be found in soil, water, dust, animal poop, and other substances. People pick up the infection most often from deli meats, soft cheese, and pates.

3.  Escherichia coli (E.Coli) are bacteria that normally live in the intestines of humans and animals. You can get this infection from ground meat that not cooked properly, unpasteurized milk, water and even from infected people or animals.  

Food poisoning can be caused by eating food contaminated with bacteria or other substances. Bacteria growth in a warmth and moisture place. The symptom that someone got food poisoning included abdominal pain, dehydration, vomiting, and diarrhea.

Contamination can occur when food incorrectly handled or cooked. People should follow good food hygiene at all times to avoid food poisoning, it is including food preparation, storing, cooking and serving. Always wash your hand after touching raw meat or poultry.
