Abstract
In a sanitary survey, nine taverns were chosen among those selling mollusk coctails, eaten raw in the city of San José so as to represent three socio-economic levels. Sixty-six samples of coctails were examined for total and fecal coliforms, Staphylococcus aureus, and salmonellas. Only 7% of the samples proved to be within the accepted limits for human consumption. No correlation was found between sample origin and its bacteriologically determined quality.References
