What is Salmonella?
Salmonella is a type of bacteria that can cause foodborne illness, commonly known as salmonellosis. It is often found in raw or undercooked meat, poultry, eggs, and sometimes in unwashed fruits and vegetables. Salmonella can also be present in the feces of infected animals, which can contaminate food and surface areas.
In the human body, Salmonella can invade the intestinal lining and lead to an inflammatory response. This can cause various symptoms such as diarrhea, fever, and abdominal cramps. The illness typically begins six hours to six days after exposure to the bacteria and can last anywhere from four to seven days, although some individuals may experience more severe symptoms or complications.
How does food become contaminated with Salmonella?
Food can become contaminated with Salmonella through various sources and processes. One of the most common ways is through improper handling during food preparation, where raw meat or eggs may come into contact with fruits, vegetables, or other foods that are eaten raw. Cross-contamination can occur easily if utensils, cutting boards, or hands are not properly cleaned after handling contaminated foods.
Additionally, Salmonella can be transmitted from animal to human through the consumption of contaminated products. For example, poultry and livestock can harbor the bacteria without showing symptoms, and when these animals are processed or cooked inadequately, the bacteria can persist in the food. Furthermore, Salmonella can grow in foods that are not stored at the correct temperatures, making safe food handling practices crucial for preventing contamination.
What are the symptoms of Salmonella infection?
The symptoms commonly associated with a Salmonella infection include diarrhea, fever, abdominal cramps, headache, and vomiting.
