Resumo
Nos últimos anos, o segmento de alimentos para animais de estimação no Brasil apresentou um expressivo crescimento no volume de vendas. O mercado brasileiro de rações para cães apresenta os maiores índices de crescimento mundial. Com os objetivos de verificar a qualidade higiênico-sanitária e a influência da venda a granel foram analisadas 15 marcas de rações para cães, em duplicata, oriundas de embalagens fechadas e da comercialização a granel. As amostras foram obtidas no comércio varejista dos Municípios de Jaboticabal e Ribeirão Preto/SP. Foram realizadas as determinações dos números mais prováveis de coliformes totais e termotolerantes, as contagens de bolores e leveduras e microrganismos mesófilos e a pesquisa de bactérias do gênero Salmonella. Os resultados obtidos evidenciaram que não houve diferença significativa nas contagens de bolores e leveduras e microrganismos mesófilos entre as amostras comercializadas em embalagens fechadas e a granel. Entretanto, nas amostras de rações comercializadas em embalagens fechadas foram verificadas maiores porcentagens de amostras contaminadas por bolores e leveduras e maior presença por indicadores de contaminação fecal. Não foram isoladas bactérias do gênero Salmonella nas amostras analisadas. Sugere-se que na comercialização a granel a ração seja embalada, para com isso preservar a qualidade microbiológica do produto.
In the past years, pet food segment in Brazil has been experiencing a marked increase in sales' volume. The Brazilian dog food market has the world's highest growth rate. This study is aimed to verify the influence of in bulk sales and the hygienic-sanitary quality of dog food. Fifteen brands of dog food obtained from packages and from in bulk marketed were analyzed in duplicate. The samples were collected from retailers of Jaboticabal y Ribeirão Preto Municipality/SP. The most probable number of total coliforms and heat-resistant ones, the counts of yeasts, molds and mesophils, and Salmonella investigation were performed. Results for counts of yeasts, molds and mesophils showed no statistical significance between packed and in bulk food. However, it was verified that samples of in bulk food had greater percentage of molds, yeasts and fecal indicators contaminations. No bacteria of the genus Salmonella was found in analyzed samples. This study suggests that in bulk marketing should pack dog food in order to preserve its microbiological quality.
