Resumo: | Introduction: Raw hardwood vegetables are possible sources of microbiological contamination and need to be sanitized before consumption. The different sanitizers vary in their ability to reduce microorganisms, and chlorine, in its different forms, is widely used in food for this purpose. Objective: To evaluate the efficacy of three different types of commercial domestic sanitizers in the reduction of microbial load on in natura crisplettuce from conventional cultivation. Method: Five lots of three different chlorine-based sanitizers used for lettuce sanitization were studied. Concentration of free chlorine and the existence of thermotolerant coliforms and Salmonella spp were investigated in the lettuce samples after sanitization. Results: Only one of the evaluated sanitizers obtained free chlorine concentration between 100 and 200 ppm. All lettuce samples showed an absence of Salmonella sp./25 g and 60% of them had no reduction of coliform at 45ºC to acceptable evels for the product to be suitable for consumption. Conclusions: The tested products were not effective in reducing the microbial load of lettuce to safe levels, which may be putting the health of the consumer at risk. However, more studies are needed to elucidate issues related to the food hygiene process. |

Os diferentes saneantes variam quanto à sua capacidade de redução de microrganismos, e o cloro, em suas diferentes formas, é amplamente utilizado em alimentos para este fim. Objetivo: Avaliar a eficácia de três diferentes tipos de saneantes comerciais de uso doméstico na redução de carga microbiana em alface crespa in natura de cultivo convencional. Método: Foram estudados cinco lotes de três diferentes saneantes comerciais à base de cloro utilizados para sanitização de alface; avaliada a sua concentração de cloro livre e pesquisados coliformes termotolerantes e Salmonella spp. nas amostras de alface após a sanitização. Resultados: Apenas um dos saneantes avaliados obteve concentração de cloro livre entre 100 e 200 ppm. Todas as amostras de alface apresentaram ausência de Salmonella sp./25 g e 60% delas não tiveram redução de coliformes a 45ºC a níveis aceitáveis para que o produto estivesse próprio para o consumo. Conclusões: Os produtos testados não foram eficazes para reduzir a carga microbiana da alface a níveis seguros, o que pode estar colocando em risco a saúde do consumidor. Contudo, mais estudos são necessários para elucidar questões relativas ao processo de higienização de alimentos.Instituto Nacional de Controle de Qualidade em Saúde2019-05-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersion"Peer-reviewed article""Artículo revisado por pares""Artigo avaliado pelos pares"application/pdfapplication/pdfhttps://visaemdebate.incqs.fiocruz.br/index.php/visaemdebate/article/view/125810.22239/2317-269x.01258Health Surveillance under Debate: Society, Science & Technology ; Vol. 7 No. 2 (2019): May; 82-86Vigilancia en Salud en Debate: Sociedad, Ciencia y Tecnología; Vol. 7 Núm. 2 (2019): Puede; 82-86Vigil Sanit Debate, Rio de Janeiro; v. 7 n. 2 (2019): Maio; 82-862317-269Xreponame:Vigilância Sanitária em Debateinstname:Fundação Oswaldo Cruz (FIOCRUZ)instacron:FIOCRUZporenghttps://visaemdebate.incqs.fiocruz.br/index.php/visaemdebate/article/view/1258/1016https://visaemdebate.incqs.fiocruz.br/index.php/visaemdebate/article/view/1258/1074Copyright (c) 2019 Vigilância Sanitária em Debate: Sociedade, Ciência & Tecnologia (Health Surveillance under Debate: Society, Science & Technology) – Visa em Debatehttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessSouza, Isabela Pais deBaptista, Nathália FerreiraAssis, Rebeca Melgaço deMiyahira, Roberta FontaniveGuimarães, Renata Rangel2023-06-27T15:11:12Zoai:ojs.visaemdebate.incqs.fiocruz.br:article/1258Revistahttps://visaemdebate.incqs.fiocruz.br/index.php/visaemdebatePUBhttps://visaemdebate.incqs.fiocruz.br/index.php/visaemdebate/oaiincqs.visaemdebate@fiocruz.br || gisele.neves@fiocruz.br2317-269X2317-269Xopendoar:2023-06-27T15:11:12Vigilância Sanitária em Debate - Fundação Oswaldo Cruz (FIOCRUZ)false |
