Resumo: | Green coconut water is rich in nutrients and widely consumed in the world. However, the consumption of coconut water out of good practices for food production treat consumer health. The aim of this work was to evaluate the microbiological quality of coconut water sold by vendors street in Sobral - CE. Samples of fresh coconut water were collected bimonthly from four different points (named A, B, C and D) during 12 months (n=24). Samples were characterized by quantification of total coliform (TC), thermotolerant coliform (TTC) and mesophilic aerobic bacteria (MAB). The Most Probable Number (MPN) and Pour Plate techniques were applied to quantification of TC and TTC, and mesophilic aerobic bacteria (MAB), respectively. All samples presented contamination by TC, TTC and MAB. TC-MPN ranged from 4.97x104 MPN/mL to 1.18x105 MPN/mL, and TTC-MPN ranged from 8.39x102 MPN/mL to 1.28x103 to MPN/mL. Samples C and D presented contamination by Escherichia coli. The number of MAB ranged from 3.12x104 CFU/mL to 6.73x104 CFU/mL. TTC number are above of the permitted values according to National Health Surveillance Agency (ANVISA), being considered as unsuitable for human consumption. Then, it is necessary to adopt preventive measures and good hygiene practices in coconut water commercialization for improvement of the microbiological quality of the product and prevent risks to consumers health. |

However, the consumption of coconut water for good food production practices harms the health of the consumer. The objective of this work was to evaluate the microbiological quality of coconut water marketed by camels from Sobral - Ceará. Samples of fresh coconut water were collected bimonthly at four different points (named A, B, C and D) for 12 months (n=24). The samples were characterized by the quantification of total coliforms (TC), thermotolerant coliforms (TTC) and mesophilic aerobic bacteria (MAB). The Most Provable Number (MPN) and Pour Plate techniques were applied for the quantification of TC and TTC, and mesophilic aerobic bacteria (MAB), respectively. All the samples presented contamination by TC, TTC and MAB. TC-MPN varied from 4.97x104 MPN/mL to 1.18x105 MPN/mL and TTC-MPN varied from 8.39x102 MPN/mL to 1.28x103 to MPN/mL. The samples C and D presented contamination by Escherichia coli. The number of MAB varied from 3.12x104 CFU/mL to 6.73x104 CFU/mL. The TTC numbers are above two values allowed by the National Health Surveillance Agency (ANVISA), being considered unsuitable for human consumption. Likewise, it would be necessary to adopt preventive measures and good hygiene practices in the commercialization of coconut water to improve the microbiological quality of the product and prevent risks to the health of the consumer.A água de coco verde é rica em nutrientes e amplamente consumida no mundo. No entanto, o consumo de água de coco fora das boas práticas de produção de alimentos prejudica a saúde do consumidor. O objetivo deste trabalho foi avaliar a qualidade microbiológica da água de coco comercializada por camelôs de Sobral - Ceará. Amostras de água de coco fresca foram coletadas bimestralmente em quatro pontos diferentes (denominados A, B, C e D) durante 12 meses (n=24). As amostras foram caracterizadas pela quantificação de coliformes totais (CT), coliformes termotolerantes (TTC) e bactérias aeróbicas mesófilas (MAB). As técnicas de Número Mais Provável (NMP) e Pour Plate foram aplicadas para quantificação de TC e TTC, e bactérias aeróbicas mesófilas (MAB), respectivamente. Todas as amostras apresentaram contaminação por TC, TTC e MAB. TC-MPN variou de 4,97x104 MPN/mL a 1,18x105 MPN/mL e TTC-MPN variou de 8,39x102 MPN/mL a 1,28x103 a MPN/mL. As amostras C e D apresentaram contaminação por Escherichia coli. O número de MAB variou de 3,12x104 UFC/mL a 6,73x104 UFC/mL. Os números TTC estão acima dos valores permitidos pela Agência Nacional de Vigilância Sanitária (ANVISA), sendo considerados impróprios para consumo humano. Assim, faz-se necessária a adoção de medidas preventivas e boas práticas de higiene na comercialização da água de coco para melhoria da qualidade microbiológica do produto e prevenção de riscos à saúde do consumidor.Editora Universitária Tiradentes2024-05-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.set.edu.br/saude/article/view/1165210.17564/2316-3798.2024v9n3p219-231Interfaces Científicas - Saúde e Ambiente; v. 9 n. 3 (2024): Fluxo Contínuo; 219-2312316-37982316-331310.17564/2316-3798.2024v9n3reponame:Interfaces Científicas.
