CAVA, Rita; SANGRONIS, Elba; RODRIGUEZ, Marta  e  COLINA, Jhoana. MICROBIOLOGICAL QUALITY OF GERMINATED SEED OF Phaseolus vulgarisQUALIDADE MICROBIOLÓGICA DE SEMENTES GERMINADAS DE Phaseolus vulgaris. INCI [online]. 2009, vol.34, n.11, pp. 796-800. ISSN 0378-1844.

Sprouts have an improved nutritional value but have been involved in many foodborne infectious outbreaks. Aerobic bacteria, coliforms, generic Escherichia coli, yeasts and moulds were counted in dry seeds and in sprouts of two varieties of Phaseolus vulgaris. Bacillus cereus was counted in sprouts. The presence of Salmonella spp, Listeria monocytogenes, and E. coli O157:H7 was investigated. Populations of aerobic mesophiles, coliforms, moulds and yeasts increased in the sprouts with respect to the dry seeds in the two varieties of P. vulgaris. The presence of Salmonella, L. monocytogenes or E. coli O157:H7 was not detected in the dry beans nor in sprouts. However, high counts of B. cereus were obtained, which represents a health risk.
