  • Title: Bacterial pathogens recovered from vegetables irrigated by wastewater in Morocco.
    Author: Ibenyassine K, Mhand RA, Karamoko Y, Anajjar B, Chouibani MM, Ennaji M.
    Journal: J Environ Health; 2007 Jun; 69(10):47-51. PubMed ID: 17583296.
    Abstract:
    The authors obtained 50 vegetable samples from various regions in Morocco and examined them to determine the microbiological quality of these products. Aerobic count, coliform, enterococci, and Staphylococcus aureus were evaluated. This analysis revealed high levels of enterococci, fecal coliforms, and total coliforms. No coagulase-positive Staphylococcus aureus was detected in any of the samples analyzed. Biochemical identification of Enterobacteriaceae showed the presence of Citrobacter freundii (28 percent), Enterobacter cloacae (27 percent), Escherichia coli (16 percent), Enterobacter sakazakii (12 percent), Klebsiella pneumoniae (17 percent), Serratia liquefaciens (11 percent), and Salmonella arizonae (0.7 percent). The results clearly demonstrate that vegetables irrigated with untreated wastewater have a high level of microbiological contamination. Consequently, these vegetables may be a threat for the Moroccan consumer and may be considered a serious risk to Moroccan public health.
