Differential attachment to and subsequent contamination of agricultural crops by Salmonella enterica. Applied and Environmental Microbiology.74:5568-70 Interpretive Summary: U.S. salmonellosis outbreaks have occurred following consumption of tomato and cantaloupe but not lettuce. We report differential contamination among agricultural seedlings by Salmonella enterica via soil. Members of the family Brassicaceae had a higher incidence of outbreak than carrot, lettuce, and tomato. Once they were contaminated, phyllosphere populations were similar, except for tomato. Contamination differences exist among tomato cultivars. Technical Abstract: U.S. salmonellosis outbreaks have occurred following consumption of tomato and cantaloupe but not lettuce.
