| Petrifilm EC and HS were compared to the MPN method to determine their efficacy to enumerate total coliforms and E. coli in 145 samples of water (76 water in natura, 69 drinking water). For water in natura, Petrifilm HS and EC showed good correlation with MPN method. In chlorinated water (< 20 col/100 mL and negatives) the agreement was low. For E.coli enumeration, Petrifilm EC showed a good correlation with MPN method. The results indicated that Petrifilm EC and HS are accurate to enumerate coliforms and E. coli in water when the expected counts are higher than 20/100 mL. |

| Fluctuations in the Brazilian milk market force small milk producers to find temporary trade alternatives, which include selling raw milk to people who prefer this type of milk rather than heat-processed milk. Considering the importance of these small milk producers to the market and the well-known health risks associated to consumption of raw milk, this study evaluated the microbiological quality and the presence of Listeria monocytogenes, Salmonella spp., chlorine, antimicrobials and insecticides (organophosphates and carbamates) in raw milk produced in 210 small and medium farms located in four important milk-producing Brazilian states (Paraná, São Paulo, Minas Gerais and Rio Grande do Sul). In 66% of the selected farms the milking was manual. In 33% of... |
