摘要: Abstract Aims: To investigate the prevalence of Listeria monocytogenes in poultry products, and to elucidate whether products may be linked listeriosis cases. A further goal was identify contamination routes for L. broiler carcasses. Methods Results: Poultry (385 samples) were screened monocytogenes. The recovered isolates 19 patient characterized by multilocus enzyme electrophoresis restriction analysis. showed great genetic diversity, but no identical subclones identified from sources patients. One slaughterhouse examined detail during a 16-month period. rates increased along processing line, one subclone found whole Only low bacteria revealed faeces. Conclusions: The high, cases products. Broilers seem contaminated slaughter process, specific strains persist environment. Broiler faeces does not an important source products. Significance Impact Study: Preventive measures avoid must taken plants.
