dc.description.abstractThe behaviours of Shiga toxin-producing Escherichia coli (STEC), enteroinvasive E. coli (EIEC), enteropathogenic E. coli (EPEC) and enterotoxigenic E. coli (ETEC) strains on raw carrots at 3 ± 1 and 30 ± 1°C, and in unpasteurized carrot juice at 3 ± 1, 12 ± 1, 20 ± 1, 30 ± 1°C and 37 ± 1°C were determined. Raw carrots were purchased in a local market. Fresh juice was obtained from raw carrots in the laboratory. On whole carrots stored at 30 ± 1 or 3 ± 1°C, no growth was observed for any of the diarrheagenic E. coli pathotype (DEPs) strains studied. After 15 days at 30 ± 1°C, the tested DEPs had decreased from an initial inoculum level of approximately 6 log colony-forming units (CFU) to approximately 3·5 log CFU on whole carrots, while at 3 ± 1°C, they decreased from approximately 2·4 log to 1·6 log CFU. All these DEPs grew in fresh carrot juice at 12 ± 1, 20 ± 1, 30 ± 1 and 37 ± 1°C, reaching counts of approximately 4·2 log, 5·8 log, 6·7 log and 7·5 log CFU ml-1, respectively, after 24 h. At 3 ± 1°C, the DEP growth was inhibited at least during 7 days. Thus, storage of carrot juice at unrefrigerated temperatures can result in DEP growth to levels likely to represent a risk to consumers. © 2013 The Society for Applied Microbiology.
