What foods most commonly cause Salmonella?

Poultry (chicken, turkey) and eggs are most common. Also: raw fruits/vegetables (sprouts, melons, tomatoes), nuts (peanut butter, pistachios), spices, flour, pet food/treats, and even unexpected sources like backyard chickens/ducks. Contamination can occur during growing, harvesting, processing, or preparation. Cross-contamination in kitchens is common.

How long after eating contaminated food do symptoms appear?

Symptoms typically begin 6 hours to 6 days after infection (usually 12-72 hours). Illness lasts 4-7 days. Most people recover without treatment. However, the infection can spread from intestines to bloodstream and other body sites, potentially causing death if not treated promptly with antibiotics.

When should I see a doctor for Salmonella?

Seek medical care for: diarrhea lasting more than 3 days, diarrhea with fever over 102°F, bloody diarrhea, excessive vomiting preventing fluid retention, signs of dehydration (decreased urination, dry mouth, dizziness). High-risk individuals (infants, elderly, pregnant, immunocompromised) should seek care earlier.

Do I need antibiotics for Salmonella?

Most people recover without antibiotics. Antibiotics are reserved for: severe illness, bloodstream infection (bacteremia), high-risk patients (infants <3 months, elderly, immunocompromised, those with sickle cell disease or prosthetic heart valves). Unnecessary antibiotics can prolong illness and increase antibiotic resistance.

Can I get Salmonella from pets?

Yes. Reptiles (turtles, snakes, lizards), amphibians, birds, and even dogs/cats can carry Salmonella without appearing sick. Backyard poultry (chickens, ducks) are increasingly common sources. Always wash hands after handling pets, especially before eating. Don't kiss pets or let them lick your face. Don't keep reptiles as pets if you have children under 5.

How can I prevent Salmonella?

Cook foods thoroughly (165°F for poultry, 160°F for ground meat). Avoid raw/undercooked eggs, meat, poultry. Wash hands, utensils, and surfaces often. Separate raw meat from other foods. Refrigerate promptly. Don't prepare food when ill. Avoid unpasteurized dairy. Wash produce thoroughly. Practice good hand hygiene after handling pets/animals.

What is Salmonella?

Salmonella bacteria live in the intestines of animals and humans. Most infections result from eating contaminated food (poultry, eggs, produce, peanut butter). While most people recover without treatment in 4-7 days, it can be life-threatening for young children, elderly, and immunocompromised individuals. About 26,500 hospitalizations and 420 deaths occur annually in the U.S.

Symptoms

Diarrhea (may be bloody)
Fever and chills
Abdominal cramps
Nausea and vomiting
Headache
Symptoms last 4-7 days
Severe cases: Dehydration, bacteremia (blood infection)

Transmission

Eating contaminated food (especially poultry, eggs, produce); contact with infected animals (reptiles, birds, backyard poultry); person-to-person (poor hygiene); contaminated water

Contagious Period: Several days to several weeks after infection; some become chronic carriers

Prevention

Cook poultry to 165°F, ground meat to 160°F
Avoid raw or undercooked eggs and meat
Wash hands thoroughly after handling raw meat, pets, or using bathroom
Prevent cross-contamination (separate cutting boards for raw meat)
Refrigerate food within 2 hours (1 hour if temp >90°F)
Wash fruits and vegetables thoroughly
Don't prepare food when ill with diarrhea
Avoid unpasteurized milk and juice
Wash hands after handling reptiles, birds, or backyard poultry
