Diagnosis of hygienic-sanitary and microbiological conditions of hospital human milk-banks

Abstract

INTRODUCTION: Based on the assumption that foodstulfs can be the vehicle of transmission of microorganisms and microbial metabolics and considering lacteal formulas to be a nutritional and therapeutic basis for hospitalized children, the purpose of the study is the evaluation of the effect of the hygienic-sanitary conditions of hospital lactaries on the microbiological quality of the food served by them. MATERIAL AND METHOD: A sanitary survey and microbiological analyses of lacteal formulas were undertaken, as also of the raw materials from wich the utensils used were made, as well as of the conditions both the environment and the personnel, at two hospital lactaries in Florianópolis city, SC, Brazil. RESULTS AND CONCLUSIONS: On the basis of a sanitary inspection questionnaire the Lactary Services showed good hygienic-sanitary conditions. As for the milk formulas, 45.9% of the samples were contaminated by coliform group. A high level of contamination was also formad especially on nipples and plastic jans registering, respectively 75% and 58.3% of coliforms. The presence of E. coli and S. aureus was found on the hands and S. aureus was found on in the oropharynx of the lactary personnel.
