- Abstract
Background: The meat and the derivatives are meals made of proteic matrix that provides optimums conditions for different microorganism's proliferation, deteriorative and pathogen. Within this last we found E. coli enterohemorragic recognized for the first time as a human pathogen in 1982, since then, lots of infection outbreaks caused by the O157:H7 serotype were often registered in many world regions related with meat and raw vegetable. Objectives: Determination of E. coli and identify the O157:H7 serotype in meat products that are commercialized in different expended of Cartagena Bolivar. Methods: An observational, descriptive and transversal cut study was made. For the samples recollection was made a no probabilistic sampling for convenience thru a sampling simple plan type A according to the NTC 1325 for meat products and derivatives, giving a total of 70 meat samples commercialized in seven chain shops in the center zone of the city, 40 chicken samples of eleven shops and one hundred pork meat samples distributed in 60 samples of 20 high concurrence supermarkets and 40 samples from the market plaza of the city. For the microbiologic processing it was used NMP technique according to INVIMA law and for O157:H7 serotype identification it was used the Reveal device. Results: In the evaluated meat products was found not acceptable levels, more than 1100 NMP/ grams of E. coli in 36 (60%) pork meat samples from private establishment, 37 (92,5%) pork meat from municipal market, 39 (55,71%) beef meat samples and 0% in chicken. The O157:H7 serotype was identified in 17 (28%) pork meat samples from private establishment, 31 (77,5%) pork meat samples from municipal market, 21 (30%) beef meat samples and 13 (32,5%) chicken samples. Conclusions: The high levels of E. coli and O157:H7 serotype show a potential risk that represent in public health for all the costumers and the microbiologic low quality in meat products commercialized in the city, however, finding low E. coli concentration in meat matrix is not always an indicative of a pathogen absence.
