“…Despite the broad numerical variation of the TtC found in the samples, this result is of utmost importance in public health due to the potential of these foods as sources of infections and foodborne infections (Martins et al, 2010) In the correlation analysis with the presence of TtC, there was association for the risk factor use of reservoir water where there was release of wastewater and absence of sanitization of the vegetables at the moment of harvesting (Table 3). The results obtained in this work corroborate those obtained by Santos et al (2010), who studied the hygienic and sanitary quality of vegetables and irrigation water in Salvador -BA, Brazil, and detected unsatisfactory conditions of the investigated areas and the elevated number of vegetables and the water used for their irrigation, which presented contamination by TC and TtC. Such a result was also confirmed by Mattos et al (2009), who affirmed that the microbiological contamination in vegetables is due to the use of contaminated water for irrigation.…”

“…Já o estudo realizado por Silva et al (2013) com alfaces (Lactuca sativa L.) comercializada em Anápolis no estado de Goiás, enfatizou a contaminação por nematódeos devido ao seu potencial de contaminação. Também Santos et al (2010), ao estudarem a qualidade higiênico-sanitária de hortaliças e águas de irrigação em Salvador na Bahia, revelaram as condições precárias das áreas examinadas e o amplo número de vegetais, bem como a água utilizada para a irrigação desses, que apresentaram contaminação por coliformes termotolerantes e E. coli. Montanher et al (2007) em seu trabalho, averiguaram que 10% das alfaces servidas em restaurantes self-service por quilo, localizadas no centro da cidade de Curitiba-PR, apresentaram algum parasita intestinal.…”

“…Desse modo, as amostras de alface das propriedades C e E, e as amostras de coentro das propriedades C e D, apresentaram contagens de coliformes de origem fecal acima do que é permitido pela legislação brasileira (Tabela 1). Em um estudo realizado por Santos et al (2010) também foram encontrados índices elevados de contaminação por coliformes a 45°C; dentre as hortaliças analisadas, a alface e o coentro foram os que apresentaram maior incidência de contaminação; e nas amostras de água de irrigação, 89% foram positivas para coliformes totais e 87% apresentaram coliformes termotolerantes. Assis e Uchida (2014) afirmam que contagens elevadas de coliformes podem indicar condições higiênico-sanitárias insatisfatórias no processamento ou pós-processamento dos alimentos.…”
