Resumo:
The availability of nutrients in milk, its high water activity and its pH close to neutrality
makes it an extremely favorable medium for microbial growth. The hygienic-sanitary
conditions adopted in the production system, in the processing and in the
commercialization of raw milk are indispensable factors for its microbiological quality to
be satisfactory. In general, the microbial load of the milk depends on the number of
microorganisms that come into contact with the milk before milking or through
subsequent contamination. Eight samples of milk sold in six municipalities located in the
hinterland of the State of Paraíba (Sousa, Pombal, Cajazeiras, Patos, Coremas and Catolé
do Rocha) were collected, thus totaling forty-eight samples. They were evaluated for
microbiological quality and the parameters evaluated were: Coliforms at 35 and 45ºC
(NMP / ml), Salmonella sp. (absence / presence), Total count of Aerobic Mesophilic
bacteria (CTM) (UFC / ml) and Filamentous fungi and yeasts (UFC / ml). In the results
obtained, it was possible to observe the high microbial load in the analyzed samples. For
coliforms at 45 ° C, averages ranged from 150 NMP / ml to 1100 NMP / ml, thus
indicating hygiene deficiencies during the process of obtaining milk. The city that
obtained less contamination in its samples in relation to filamentous fungi and yeasts, was
Coremas, whereas the city of Patos presented the highest average among the analyzed
samples. Samples analyzed in Cajazeiras, Pombal and Catolé do Rocha were
contaminated with Salmonella spp. The milk samples analyzed showed unsatisfactory
hygienic-sanitary conditions, presenting a high microbial load and thus presenting a risk
to the consumer's health.
