Inhibition of Listeria monocytogenes and Salmonella enteritidis on chicken wings using scallop-shell powder.

The present study was designed to determine the inhibitory effect of scallop-shell powder (SSP) on Listeria monocytogenes and Salmonella enteritidis on chicken wings. Chicken wings artificially inoculated with L. monocytogenes (8.3 log(10) cfu/g) or S. enteritidis (8.8 log(10) cfu/g) were immersed in distilled water (0.10 or 0.50% wt/vol) of SSP slurries for 10 or 30 min, respectively. The amount of L. monocytogenes, S. enteritidis, mesophilic aerobic bacteria (MAB), and yeast or mold was determined for the chicken wings at d 0 or 7 of storage at 4°C. Results indicated that 0.5% SSP decreased the amount of L. monocytogenes and S. enteritidis on chicken wings by 3.7 and 5.0 log(10) cfu/g, respectively. The growth of L. monocytogenes, S. enteritidis, MAB, and yeast or mold was inhibited by SSP during the 7-d refrigerated storage. Color and odor of chicken wings were not significantly changed by SSP treatment (P > 0.05).
