Enterobacterial contamination of meat foods consumed in the FESI and its periphery

Abstract

The diseases transmitted by food are those

that originate for the ingestion of food contaminated

in sufficient quantities to affect the health. The aim

of this research was to identify enterobacter in meat

food consumed in establishments and ambulant

positions near to the Faculty of Top Studies Iztacala.

Descriptive, across section and prospective study.

10 sites food sale were selected randomly. The

microbiological procedures were based on NOM-

114-SSA1-1994 standards.NOM-065-SSA1-1993.

And the NOM-092-SSA1-1994.

For detection of Enterobacteriaceae family

in meat, they are carried out two phases: phase

presumptive (biochemical tests: SS Agar, MacConkey

Agar, Gram stain and light microscopic observation);

and the confirmatory stage where was used as a

culture medium Lactose broth brilliant green bile. In

mesophilic test they found 90% positive; coliforms

we obtained in 42%; presence of fecal coliforms

in 64%, these results indicate the presence of

enterobacterial load at 95% of the samples studied;

It is 25% owned by Salmonella; Gram staining 95%

were gram-negative. The environment influences

directly the health of the persons, since an inadequate

managing in the food preparation can drive to

the increase in the prevalency of gastrointestinal

diseases.
