Evaluación de la condición sanitaria de la planta de lácteos Tunshi – ESPOCH.

Abstract

The objective of this research was to evaluate the current sanitary situation of the specialized dairy plant in Tunshi Town located 12 km from Riobamba City, in the province of Chimborazo. The experimental study began with the diagnosis of sanitary conditions based on the ARCSA resolution N°067-2015, using as a tool a check list of Good Manufacturing Practices (GMP). Then, sampling was done in triplicate on different days of water, live and inert surfaces that come into contact with raw materials and inputs during the manufacturing process. Pathogenic microorganisms such as Aerobic mesophiles, Staphylococcus aureus, Enterobacteriaceae, Escherichia coli, Listeria monocytogenes were counted using petrifilm TM 3M plates, molds and yeasts (NTE INEN-ISO 21527-1), and the presence or absence of salmonella (petrifilm TM 3M plates) and protozoan oocysts was also analyzed according to NTE INEN 1108. The results of the Good Manufacturing Practices checklist, according to the ARCSA resolution, were only 56.05% applicable. According to the microbiological analyses, it was determined that the water and the live and inert surfaces that come into contact with the food exceeded the permitted limits according to (NTE INEN 1108, Ministerial Resolution Nº461-2007/MINSA, NOM-093-SSA1-1994 and Regulation (EC) 2073/2005). It is concluded that due to the lack of BPMS and POES there was presence of pathogenic microorganisms on the surfaces and water of the plant. It is recommended to implement the improvement plan starting with the potabilization of water and with respect to the internal structure of the plant should be improved to reduce contamination from the outside.
