Abstract: AbstractContamination sources, biofilm‐forming ability and biocide resistance of Shiga toxin‐producing Escherichia coli O157:H7 and non‐O157 from two tilapia‐processing plants were assessed. The application of unsuitable handling and sanitizing procedures caused a wide contamination by thermotolerant coliforms in Factories A (51.2% of points) and B (66.7%), exceeding the legal limits for frozen tilapia fillets. E. coli was also detected in both factories, but at low concentrations. RAPD‐PCR using primers DAF4, GEN15001, and M13 charac...
