CHAVARRIA HERNANDEZ, Claudia Zamantha et al. Presence of enterobacteria in agricultural inputs in La Comarca Lagunera. Rev. Mex. Cienc. Agríc [online]. 2019, vol.10, n.5, pp.999-1009.  Epub 03-Mar-2020. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v10i5.1812.

The global food trade situation forces exporting countries to strengthen their control systems and adopt and monitor safety control strategies based on the risk of contamination. The objective of this research was to isolate enterobacteria in various inputs used in agricultural production in La Comarca Lagunera and to determine the risk involved in its use in agricultural activities. Samples were microbiologically analyzed from different sources of water, manures and soil, used in the agricultural production of La Comarca Lagunera, Mexico, during the years 2014-2016. Klebsiella spp. to was identified as the main risk factor of bacterial contamination in water that is used for irrigation of different crops with a prevalence of 46.95%. In the soil samples, only Klebsiella spp. with a prevalence of 60%, while in samples of bovine manure E. coli (30%) and Klebsiella spp. (40%), Salmonella spp. (14%) in goat manure, and Salmonella spp. (100%) in chicken manure. The above represents a risk factor for the health of the final consumer, in the case of producers who intend to export their agricultural products, they would reduce competitiveness and could close international markets. Further investigation is necessary along the fruit and vegetable production chain in order to reduce this contamination.

Palabras llave : E. coli; Klebsiella spp.; Salmonella spp.; agricultural safety.
