Bacteria survive washing and disinfection in food production plants

This study found that routine cleaning and disinfection in chicken and salmon processing plants significantly reduces bacterial counts (by over 90 %), but does not eliminate all bacteria. Some potentially harmful species—such as Escherichia coli, Enterococcus faecalis, Acinetobacter baumannii, and Pseudomonas aeruginosa—were still detected after disinfection, with slightly higher levels observed in Romanian facilities compared to Norwegian ones.
