O objetivo deste trabalho foi realizar análises microbiológicas das amostras de alfaces, variedade crespa, provenientes de diversos pontos de comércio da cidade de João Pessoa (PB), utilizando a técnica dos tubos múltiplos para as análises. Constatou-se a presença de coliformes totais e fecais nas diversas amostras de alfaces. Com base nos resultados obtidos vale ressaltar a importância desta análise em relação à higiene das alfaces, levando em conta que ao estarem contaminadas e expostas ao consumo, poderão causar sérios danos à saúde humana. <!--[if gte mso 9]><xml> <w:LatentStyles DefLockedState="false" DefUnhideWhenUsed="true" DefSemiHidden="true" DefQFormat="false" DefPriority="99" LatentStyleCount="267">
