The behavior of Salmonella Typhimurium, Salmonella Typhi, Salmonella Agona and Salmonella Montevideo in raw carrot at 30 ± 1 and 3 ± 1°C and in unpasteurized carrot juice at 3 ± 1, 12 ± 1, 20 ± 1, 30 ± 1 and 37 ± 1°C was determined. Fresh juice was obtained from carrots in the laboratory. Raw carrots were collected from a market in Pachuca city, Hidalgo, Mexico. On whole carrots stored at 20 ± 1 or 3 ± 1°C, no growth was observed for Salmonella strains. After 15 days at 30 ± 2°C, Salmonella serotypes decreased from an initial inoculum level of approximately 6 log CFU to 3.4 log in all the carrots; and at 3 ± 1°C, they decreased from approximately 2.6 log CFU to 1.7 log. All Salmonella serotypes grew in carrot juice at 12 ± 1, 20 ± 1, 30 ± 1 and 37 ± 1°C, reaching counts of approximately 4.3, 6, 6.8 and 7.5 log CFU/mL, respectively after 24 h. At 3 ± 1°C, the Salmonella growth was inhibited at least for 7 days.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
