Occurrence of Escherichia coli and Coliforms in Minas Cheese Plants from S?o Paulo, Brazil

“…Taking into account the shelf life of Minas cheeses (30 days) indicated by the plants evaluated, the high E. coli counts certainly undermines the microbiological quality of cheeses as a result of microbial growth. The E. coli counts found in the present study are similar to those previously reported [9,[16][17][18], showing up to 93% of Minas cheese or other soft cheeses commercially available at sales points with fecal coliforms above the tolerance limit established by legislation.…”

Analysis of virulence genes in Escherichia coli isolated from grated cheese

“…A previous research stated that 93.3% of raw cheese samples from free markets of Cuiabá -MT had levels of faecal coliforms higher than the limit established by the Brazilian legislation (LOGUERCIO; ALEIXO, 2001 There is a close association between the development of human diseases and the presence of additional virulence markers. One of those markers is the eae gene, which encodes an outer membrane protein required for intimate attachment to the host intestinal mucosa (COBBOLD; DESMARCHELIER, 2001).…”

Qualidade bacteriológica de queijos artesanais comercializados em estradas do litoral norte do Rio Grande do Sul, Brasil

“…Das 80 amostras de queijo, 18 apresentaram contagens de coliformes totais superiores a 6 log.UFC g -1 na última diluição, impossibilitando o isolamento de colônias para confirmação de coliformes fecais. Nas 62 amostras restantes, foi observada a presença de coliformes fecais com contagens entre 2,77 e 5,81 log.UFC g -1 (Tabela 1), sendo que 52 amostras (84%) apresentaram contagens acima de 2,73-3,7 log.UFC g -1 (de 500 a 5.000 UFC mL insatisfatória destes produtos comercializados no país e destacado que não têm sido observadas melhoras neste sentido (ARAÚJO et al, 2001;LOGUERCIO & ALEIXO, 2001;IDE & BENEDET, 2001;FEITOSA et al, 2003).…”
