Weibull analysis of death curves for C. jejuni 2097E48, C. jejuni 11168, and E. coil K-12 at 56°C in nutrient broth, before and after exposure to 6°C^a

Strain	α (mean ± SE)		P value	β (mean ± SE)		P value
	Control	Chill group		Control	Chill group
C. jejuni 2097E48/1	0.410 ± 0.04	0.652 ± 0.23	0.185	0.789 ± 0.13	0.466 ± 0.32	0.11
C. jejuni 11168	0.611 ± 0.09	0.475 ± 0.06	0.0006	0.546 ± 0.04	0.697 ± 0.11	0.073
E. coli	0.479 ± 0.05	0.50 ± 0.014	0.21	0.519 ± 0.07	0.674 ± 0.72	2.6 × 10−5

^aWeibull analysis was performed on resulting death curves for triplicate biological replicates of each bacterial strain at 56°C, recovered on BA plates before and after exposure to 6°C. P values of <0.05 were considered significant and are shown in bold.
