Egg shells were dipped in a solution of Salmonella enteritidis 10,118 with a concentration of 7 x 10 cfu/ml to assess Salmonella cross-contamination. PA and PAL coatings did not have a significant effect on shelf-life based on physico-chemical properties. The egg shells treated with PA and PAL coatings had a significantly lower microbial population compared to the uncoated egg shells. PA and PAL coatings effectively inhibited the growth of Salmonella after 1 and 7 days of storage, respectively. In addition, no outgrowth was observed up to 42 days.
