| Summary: | Ambrosia is a type of Dulce de Leche hand-made with milk, eggs and sugar, widely consumed in South America, and it is commonly sold in street markets, supermarkets and candy shops. Food contamination by pathogenic micro-organisms usually occur during the processing steps, at the distribution centers, at the retail market or in the consumer home. This study aimed at evaluating the behavior of the pathogenic strains of Escherichia coli enterohemorrhagic (EHEC) ATCC 43895, enteropathogenic (EPEC) INCQS 00182 and enteroinvasive (EIEC) ATCC 43893 in ambrosia samples. Aliquots of ambrosia were experimentally contaminated by the strains analyzed in this study. Detections of the inoculated microorganisms were done at 0, 1, 2, 3, 4, 5, 10, 20 and 30 days of storage. EHEC was recovered from all of analyzed samples until five days after infection. EPEC survived in ambrosia and it was isolated until the fourth day of the experiment. EIEC strain remained viable during the 30 days of storage. The analyzed pathogenic strains of E. coli showed different behavior in ambrosia, but all of them demonstrated potential danger to the consumers health. This study works for warning to adopt appropriate hygiene and sanitary actions during the ambrosia production, packaging and manipulation. |
