Sodium nitrite (NaNO2) is commonly used in meat products manufacturing for its antimicrobial effect on Clostridium botulinum, responsible of botulism (a deadly paralytic disease) by production of neurotoxins. Its use can nevertheless be associated with nitrosamines production, which are considered as carcinogenic substances (EFSA, The EFSA Journal, 2013, 14: 1-31). The objective of the present study was to compare the growth and toxinogenesis of psychrotrophic C. botulinum Group II (non-proteolytic) type B in cooked ham and in frankfurters in function of the NaNO2 incorporation rate (0, 30, 60 and 80 mg/kg) in order to evaluate the risk associated with this pathogen in two common cooked meat products.
