Salmonella is a type of bacteria that can cause food poisoning in humans. It is commonly found in raw or undercooked foods, especially poultry, eggs, and meat. When ingested, it can lead to symptoms such as diarrhea, fever, and abdominal cramps, usually appearing six hours to six days after exposure. To prevent salmonella infection, it is important to practice good food safety habits. This includes cooking foods to the right temperature, washing hands and surfaces often, and avoiding cross-contamination between raw and cooked foods. Proper food handling can significantly reduce the risk of infection.
