Objective. To identify Escherichia coli 0157:H7 present in diarrheal feces of lactating ruminants with diarrheal syndrome and safety of colostrum intake. Materials and methods. A feces sampling of 316 ruminants was carried out during the period of August 2015 to March 2016 in the municipalities of Río Grande, General Enrique Estrada, Morelos and Calera de Victor Rosales of the state of Zacatecas, obtained from 67 cattle, 183 sheep and 66 goats. Results. The following were identified in CHROMagarTM chromogenic medium: 260 coliforms, 78 Escherichia coli 0157:H7, 16 Proteus spp. and 25 colonies of unidentified bacteria, finding an incidence of Escherichia coli 0157:H7 of 22.03% in the four municipalities. Conclusions. Escherichia coli 0157:H7 is the second bacteria found in ruminant feces with an incidence of 22%, which is a mortality risk factor in lactating ruminants (less than 21 days old), causing economic loss and health risk for the population of the state of Zacatecas.
