Fig. 4. Heat inactivation of C. perfringens spores in poultry meat. Spores from a cocktail
of 5 food poisoning isolates were incubated at 55 C in poultry meat with 50 mM AK
(grey, black and vertical-line bars) and without germinants (white bars). At various
times aliquots were heat treated at: 80 C for 20 min (grey bars); 90 C for 10 min
(black bars); 90 C for 20 min (white and black bars). Survivors were determined as
described in Materials and methods.
