Avaliação higiênico sanitária e microbiológica em plataforma de recepção de leite cru refrigerado

Abstract

This work deals with the hygienic-sanitary and microbiological assessment in receiving platforms of refrigerated raw milk, with the purpose of evaluating the microbiologic quality of milk and identifying critical points in sanitation. The relevance of this study lies in the importance of adequate control of the quality of raw milk to ensure food safety and public health. The objectives include the assessment of compliance with the requirements of the Good Manufacturing Practice Manual (BPF) and the conduct of physico-chemical and microbiological analyses on samples collected on raw milk reception platforms, such as samples of milk from isothermic truck, storage silo and of refrigerators from rural producers. The methodology involved the use of ANVISA’s CRC verification sheets no. 275/2002 to verify compliance with good practices in the reception of milk, as well as the application of microbiological techniques, such as plating on petrifilm and swab plates. The results indicated that Clean in Place process (CIP) contributed to reducing the number of microorganisms in areas of the silo and in the truck tanks, but was not effective to stop this growth. However, non-standard counts were observed in milk samples from one of the tanks, seven of the twenty samples collected in rural properties and in the silo sample, which were sent to a licensed laboratory. Therefore, improving hygiene practices both in the field and on the reception platform is crucial to avoid future problems. Microbiological analysis has emerged as a crucial tool for identifying critical points, subsidizing corrective decisions and monitoring the microbiological quality of milk. Implementing improvements in this process will contribute to food safety, compliance with regulations and consumer confidence.
