Salmonella infection is caused by bacteria that can be found in contaminated food or water. Common sources include undercooked eggs, poultry, and unwashed fruits and vegetables. Symptoms typically appear 6 hours to 6 days after exposure and may include diarrhea, fever, and abdominal cramps. Most people recover without treatment, but some cases can be severe. To prevent Salmonella infection, it is important to practice good hygiene, such as washing hands before handling food and cooking meat thoroughly. Additionally, avoiding cross-contamination in the kitchen can help reduce the risk of infection.
