Abstract

The objective of the current investigation was to determine the presence or absence of Salmonella spp. and E. coli in shrimps commercialized in the supply points of a market in General Villamil Playas. The study was based on the NTE INEN 456: 2013 first revision "Shrimps or Frozen Prawns" where the requirements of fresh frozen shrimp are indicated. A sampling plan was made for each microorganism, five food stalls were studied which were sampled for five days (Monday, Tuesday, Wednesday, Thursday and Friday) in two times each day. For the determination of Salmonella spp., the Reveal 2.0 method was used and for E. Coli, it was used the Petrifilm method. Each sample was analyzed in triplicate and the results obtained were compared with the microbiological requirements of the INEN Standard. For Salmonella, it was determined the absence in the samples, while the data obtained from E. coli there were counts, which were entered into the Minitab 18 program to determine the differences between the food stalls.
