The objectives of this study were to determine the efficacy of X-ray irradiation on the inactivation of a 3-
strain mixture of Salmonella enterica (S. Enteritidis E190-88, S. Typhimurium ATCC 14028, and S. Montevideo
ATCC 8387) using an RS 2400 X-ray system on chicken breast fillets and shell eggs and to
evaluate the effect of X-ray treatments on the shelf life of chicken breast fillets and shell eggs during 20
day storage at 5 C (chicken breast fillets (25 g) or whole shell egg samples were treated with the 0.1 and
2.0 and 0.1 and 1.0 kGy, for chicken and shell eggs, respectively, and stored at 5 C for 20 days. Samples
were examined for psychrotrophs and mesophiles counts at 0, 5, 10, 15, and 20 days).
