原始语种摘要: Fruits and fruit pulps are widely consumed worldwide due to their nutrients, flavors and varieties. However, these products become contaminated with pathogens during harvest or production, which are risks to consumers. This study analyzed the microbiological quality of frozen fruit pulps and minimally processed fruits sold in supermarkets and the presence Salmonella sp. and pathogenic Escherichia coli. Almost all frozen fruit pulps samples were adequate to consume, only one samples of unpasteurized mango pulp was positive for E. coli carrier of est1b gene that codify thermostable toxin of Enterotoxigenic E. coli. Minimally processed fruits presented high yeast and mold counts in 36.25% (29/80) of the samples and 27.6% (22/80) had thermotolerant coliforms. In addition, one sample of grated...
