Resumen en inglés

The companies dedicated to the production, packaging and distribution of food must have strict quality control mechanisms that ensure the harmlessnessof the products they manufacture, that is why the Colanta Cooperative, from the quality control area, makes adjustments to guarantee the safety of the same. In the Microbiology laboratory, it is where the analyzes are carried out that allow verifying the quality compliance established for each of the manufactured products. However, these methods require verification to demonstrate that it meets the requirements to be used under laboratory conditions and in turn comply with the provisions of Resolution 1619 of 2015. This is the case of the verification of PetrifilmTM RYM in the Jenaro Pérez-Medellín plant that was carried out under strict protocols, which provided reliable results, which allows use for the analysis of the products in question, this can be verified with the variables to be determined (intermediate precision, bias and recovery percentage) The values of which expressed in the results meet these conditions to be put into routine for the matrices analyzed (milk cream and Tampico). With all the results obtained, it can be determined that the alternative method has all the conditions to be used, providing results in the expected times, providing ease in reading, generating ease of use and better management of the spaces used for incubation thereof.
