Influência da sanificação da água e das práticas de ordenha na qualidade do leite

Abstract: RESUMO Objetivou-se avaliar a influência da cloração da água utilizada em salas de ordenha, assim como do manejo e da infraestrutura da ordenha, sobre a qualidade microbiológica da água e do leite. Foi instalado um equipamento para cloração de água, por duas semanas, na caixa de água de 20 propriedades leiteiras. Foram coletadas amostras de água e leite ao primeiro dia (sem cloro: controle), no sétimo e 14° dias (com cloro) e no 21º dia após a desinstalação dos cloradores (sem cloro: controle). Foram realizada… Show more

“…Silva and collaborators [20] corroborate this, stating the importance of chlorination and microbiological evaluation of water periodically, as in Santa Catarina the authors implemented an automatic chlorinator at the entrance of the water tank of twenty dairy farms and after a period of two weeks the equipment was removed, and water and milk samples were collected, before and after the chlorine treatment. As for the results, they observed that the efficient chlorination process promoted an increase in the microbiological quality of the water with a decrease in total coliforms and pathogenic microorganisms, confirming the need for correct water treatment and the benefit of applying Good Practices.…”

“…Cleaning the pre-milking ceiling is of fundamental importance for obtaining milk with low microbiological contamination (Córdova et al, 2018). In milking management, the other fundamental procedures are pre-dipping, which minimizes the presence of microorganisms in raw milk (Silva et al, 2018), and post-dipping, which prevents contamination of the mammary gland (Machado et al, 2017). STEPDISC analysis was performed within the discriminant analysis, using the STEPWISE method, which selected the variables that made up the final model (P<0.0001) as well as those that were responsible for the differentiation of the groups (Table 3).…”

“…Dentre os fatores responsáveis por afetar a sua qualidade, estão as práticas de produção na fazenda, temperatura de permanência do leite e a distância do transporte entre a fazenda e a plataforma de recepção (LEIRA et al, 2018). Reiteradamente, essas causas afetam a multiplicação de microrganismos do grupo dos psicrotróficos no leite, devido a qualidade higiênica insatisfatória das águas (SILVA et al, 2018), sanidade dos ordenhadores e dos animais e, sobretudo, em razão de utensílios que não são perfeitamente higienizados (LEIRA et al, 2018;ARAÚJO et al, 2020).…”
