Resumo: | The sanitary evaluation of equipment and hands is fundamental to investigate the presence of pathogens in the dairy industry. Then, this study aims to evaluate the sanitization of equipment, workers’ hands, raw and pasteurized milk in goat milk dairies in the Cariri region, state of Paraíba. Collected 32 samples of four dairies represented by letters A, B, C, and D. The followings contents were analyzed: mesophiles, total and thermotolerant coliforms, Escherichia coli, Staphylococcus aureus, Samonella spp. and Listeria monocytogenes in the reception tank, pasteurization tank, packing machine, package, wall, workers’ hand, and each dairy’s raw and pasteurized milk. After isolation, 84 colonies were confirmed by MALDI TOF. The indicator microorganisms presented variations for the workers’ hands, while A and B stayed within the patterns. For the equipment, only dairy B was within limits. They were out of the standard for mesophiles, total coliforms, and thermotolerant regarding raw and pasteurized milk. The microorganisms, the Enterobacteriaceae family presented a higher frequency, with 77.38%, and within this family, Escherichia coli, Klebsiella spp., and Enterobacter spp. were the most prevalent. Gram-positive corresponded to 22.62%, Bacillus spp., Staphylococcus spp., Enterococcus spp., and Macrococcus caseolyticus. Listeria monocytogenes and Salmonella spp. were not isolated. These demonstrate failures in goat milk processing with pathogenic bacteria in several dairy plants, indicating the need to adjust the product’s quality control. |

Luego, este studio tiene como objetivo evaluar la higienización de equipos, manos de trabajadores, leche cruda y pasteurizada en lecherías de leche de cabra en la region de Cariri, estado de Paraíba. Se recolectaron 32 muestras de cuatro lecherías representadas por las letras A, B, C y D. Se analizaron los siguientes contenidos: mesófilos, coliforms totals y termotolerantes, Escherichia coli, Staphylococcus aureus, Salmonella spp. y Listeria monocytogenes en el tanque de recepción, tanque de pasteurización, empaquetadora, empaque, pared, manos de los trabajadores y la leche cruda y pasteurizada de cada lechería. Después del aislamiento, se confirmaron 84 colonias mediante MALDI TOF. Los microorganismos indicadores presentaron variaciones para las manos de los trabajadores mientras que A yB se mantuvieron dentro de los patrones. Para el equipo, solo la lechería B estaba dentro de los límites. Estaban fuera del estándar para mesófilos, coliformes totales y termotolerates con respect a la leche cruda y pasteurizada. Los microorganismos, la familia Enterobacteriaceae presentaron una mayor frecuencia, con 77,38%, y dentro de esta familia, Escherichia coli, Klebisiella spp. y Enterobacter spp. fueron los más frecuentes. Los grampositivos correspondieron al 22,62%, Bacillus spp., Staphylococcus spp., Enterococcus spp. y Macrococcus caseolyticus, Listeria monocytogenes y Salmonella spp. no estaban aislados. Estos demuestran fallas en el procesamiento de la leche de cabra con bacterias patógenas env arias plantas lecheras, lo que indica la necesidad de ajustar el control de calidad del producto.A avaliação sanitaria de equipamentos e mãos é fundamental para investigar a presença de patógenos na indústria de laticínios. Assim, este estudo teve como objetivo avaliar a higienização de equipamentos, mãos de trabalhadores, leite cru e pasteurizado em laticínios de leite de cabra na região do Cariri, estado da Paraíba. Coletaram-se 32 amostras de quatro laticínios representados pelas letras A, B, C e D. Os seguintes conteúdos foram analisados: mesófilos, coliformes totais e termotolerantes, Escherichia coli, Staphylococcus aureus, Salmonella spp. e Listeria monocytogenes no tanque de recepção, tanque de pasteurização, máquina de embalagem, embalagens, paredes, mãos dos trabalhadores e leite cru e leite pasteurizado de cada laticínio. Após o isolamento, 84 colônias foram confirmadas por MALDI TOF. Os microrganismos indicadores apresentaram variações para as mãos dos trabalhadores, enquanto A e B permaneceram dentro dos padrões. Para o equipamento, apenas o leite B estava dentro dos limites. Eles estavam for a do padrão para mesófilos, coliformes totais e termotolerantes em relação ao leite cru e pasteurizado. Os microrganismos,da família Enterobacteriaceae, apresentaram maior frequência, com 77,38%, e dentro desta família, Escherichia coli, Klebisiella spp. e Enterobacter spp. foram os mais prevalentes. Gram-positivos corresponderam a 22,62%, Bacillus spp., Staphylococcus spp., Enterococcus spp., Macrococcus caseolyticus, Listeria monocytogenes e Salmonella spp. não foram isolados. Foram demonstradas falhas no processamento do leite de cabra com bactérias patogênicas em várias fábricas de laticínios, indicando a necessidade de ajustar o controle de qualidade do produto.Research, Society and Development2021-10-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2073510.33448/rsd-v10i12.20735Research, Society and Development; Vol. 10 No. 12; e596101220735Research, Society and Development; Vol. 10 Núm. 12; e596101220735Research, Society and Development; v. 10 n. 12; e5961012207352525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/20735/18579Copyright (c) 2021 Iara Nunes de Siqueira; Aline Antas Cordeiro Cavalcanti; Joyce Galvão de Souza; Filipe Jordão Pereira de Medeiros; João Carlos Taveira; Samuel Fernandes Garcia; Claudia Morgana Soares; Suely Cristina Pereira de Lima Oliveira; Abrahão Alves de Oliveira Filho; Márcia Almeida de Melohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSiqueira, Iara Nunes de Cavalcanti, Aline Antas CordeiroSouza, Joyce Galvão deMedeiros, Filipe Jordão Pereira deTaveira, João CarlosGarcia, Samuel FernandesSoares, Claudia MorganaOliveira, Suely Cristina Pereira de Lima Oliveira Filho, Abrahão Alves de Melo, Márcia Almeida de2021-11-14T20:26:51Zoai:ojs.pkp.sfu.ca:article/20735Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:40:17.634883Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
