GUERREIRO, Paola Kiara et al. Microbiological quality of milk through preventive techniques in the handling of production. Ciênc. agrotec. [online]. 2005, vol.29, n.1, pp.216-222. ISSN 1413-7054.

The milk industry lives a time of strong transformations in your structure, and the quality of the milk is one of the most important demands.

This study was carried out  with the objective of evaluating the effect of the adoption of different preventive techniques of hygiene and cleaning, during the production handling, in the microbiological quality of milk measured for the count of psichrotrofics bacteria. The preventive techniques were appraised involving four farms milk producers. Such techniques were tested before, during and after the milk round to get being hygiene practices and cleaning of: utensils and equipments; operators / milks-man; environment of milk round; and handling of the animals. In each farm a sample was collected for control, before the adoption of the prophylaxes, and later four periodic samples were collected. Based in the applied questionnaire, it could be verified that happened flaws in the hygiene and cleaning procedures in all the farms and a lot of cows was diseased with sub-clinic infection. It was conclude that after the adoption of the techniques of prophylaxes all the farms shown significant decreases in the count of psichrotrofics bacteria, proving the importance of the hygiene and cleaning preventive practices on the milk microbiological quality.
