NEW YORK (Reuters Health) — Exposure to reptiles and being in close proximity to meat and poultry in the supermarket are two modifiable risk factors for Salmonella infection in infants, according to what may be the largest reported study of infant Salmonella infection. Salmonella is estimated to cause 1.4 million illnesses and 400 deaths each year in the US. “Rates of Salmonella infection are highest in infants, but little is known about potential sources of infection in this high-risk population,” note Dr. Timothy F. Jones of the Tennessee Department of Health in Nashville and colleagues in the journal Paediatrics.
