Escherichia coli (E. coli) O157:H7 is a major food safety threat. It has the ability to produce several virulence factors. Shiga toxins (Stxs) are the key virulence factors of E. coli O157:H7 that are responsible for hemorrhagic colitis and serious renal failure. Despite the extensive study of E. coli O157:H7 survival during meat processing, the production of Stxs by E. coli O157:H7during these processes has not been studied. This becomes a very important question since Stx2 is resistant to heat treatment. The objective of this study is to elucidate the effect of essential additives to meat products, salt and sodium nitrite, on Stx2 production by E. coli O157:H7. E. coli O157:H7 (EDL933 and 86-24) was treated with different concentrations of salt (1%, 2%, 3%, W/V) or sodium nitrite (0, 100, 200, and 300 ppm) solutions for 6 h. The Stx2 production and CFU were analyzed for both strains in both salt and sodium nitrite solutions. RecA expression, PFU, and Stx2 carrying bacteriophages were analyzed for strain EDL933 in salt solutions. Solutions supplemented with 2% and 3% salt decreased (P
