In order to evaluate the effect of simulated home pan frying of raw meat and meat preparations of different animal
species on the thermal inactivation of pathogens, the heat resistance (D-value) of three strains of Campylobacter
jejuni, Escherichia coli O157:H7, Salmonella spp., Listeria monocytogenes and two strains of generic E. coli
was validated in BHI and adjusted BHI (i.e. pH 5.6 and 1.5% NaCl) at 60 °C.
The D-values were obtained of the linear
phase of the survivor curves created in GInaFiT, a freeware tool to fit models to experimental data.
The obtained
D-values corresponded to those previously published in literature and confirmed L. monocytogenes to be the
most heat resistant pathogen among them.
