What symptoms can salmonellosis cause?

Salmonellosis is a foodborne illness typically caused by consuming food or water contaminated with Salmonella bacteria, such as raw or undercooked eggs, poultry, or meat.21

Symptoms of nontyphoidal salmonellosis generally appear within 6 to 72 hours after exposure and include:21

• Diarrhea
• Fever
• Abdominal cramps
• Nausea
• Vomiting
• Chills
• Headache

In healthy individuals, these symptoms usually resolve within several days. However, severe cases can lead to dangerous dehydration or bloodstream infections, which are particularly concerning for infants, older adults, and individuals with weakened immune systems. It is essential to practice proper food handling and hygiene to prevent infection, as food safety is a critical component of public health.21
