RESUMO

Every day foodborne diseases put a lot of people s lives at risk, this being more severe in people with weakened health conditions, such as hospitalized children. For this target population, one of the main sources of foodborne diseases is the food prepared in the hospital lactaries. Thus the importance of a quality control preventive system that guarantees the safety of foods destined for these patients is evident. This work aimed to evaluate microbiological hazards existent in the preparation of infant formula in the lactary of a public hospital, in order to adapt the establishment to the necessary prerequisites for the subsequent implantation of the Hazard Analysis and Critical Control Point system (HACCP). This evaluation was made by diagnosing the hygienic conditions of the establishment and by studying the preparation flowchart of the reconstituted infant dairy formula (IDF), for which ten sampling points were established so as to make microbiological analyses of the air, equipment and utensils, and powdered and reconstituted IDF. The samples were collected in six preparation batches, giving a total of 60 samples, which were analysed for total and faecal coliformes, coagulase negative staphylococci, Bacillus cereus, Salmonella, enterobacteriae, and the total aerobic mesophilic and psycrotrophic microrganisms. The results of the microbiological analyses showed considerable variation in the quantity of the indicative microorganisms, but no pathogens were found by the methods used. All of the powdered IDF samples were appropriate for consumption according to the norms in force, but the reconstituted IDF samples presented high quantities of all the indicative microorganisms, except for faecal coliformes. The spoon was the only utensil that was found to be appropriately clean. The stages: acquisition of the powdered formula; storage under refrigeration and heating for distribution, were identified as the critical control points of the process. From this study it was concluded that the lack of hygienic prerequisites during the preparation of the reconstituted IDF for infants resulted in a microbiologically inadequate product for children in a weakened health condition, and that implantation of the HACCP system would only be possible after the establishment had adjusted itself to attend these prerequisites.
