Radiation resistance of Campylobacter jejuni in broth, ground beef, and ground turkey meat was determined using dose levels from 0-200 Krad at -30 +/- 10/sup 0/C, at 0-5/sup 0/C, and at 30 +/- 10/sup 0/C. Irradiation at -30/sup 0/C increased radiation resistance of cultures in ground meats; broth cultures were not greatly influenced by temperature. The effect of culture age on radiation resistance was also evaluated using cells in various physiological phases. Age did not have a pronounced effect on radiation resistance. The largest D/sub 10/ value for C. jejuni was 32 Krad, which was less than D/sub 10/ values commonly reported for salmonellae. 20 references, 4 figures.
