The effects of gamma-irradiation doses (0, 0.5, and 1.0 Mrad) on C. botulinum toxin production in turkey frankfurters formulated with three different chloride salts (NaCl, KCl, and MgCl/sub 2/) at isoionic strength (equal to 2.5% NaCl) and three types of phosphates added to 2.0% NaCl frankfurters were studied. The use of 2.5% NaCl together with 0.5 or 1.0 Mrad was substantially more effective at inhibiting botulinal toxin production when frankfurters were incubated at 27/sup 0/C than the combination of irradiation with KCl or MgCl/sub 2/ (40, 9, and 4 days, respectively, when treated with 1 Mrad). Phosphate addition revealed that 0.4% sodium acid pyrophosphate addition was the most inhibitory for botulinal toxin production followed by hexametaphosphate and tripolyphosphate addition.
