indicated that the Salmonella shell contamination at the
end of storage was strongly correlated with the trans-shell penetration
as was found in this study. The 2% chitosan coating significantly
decreased trans-shell penetration. The slightly lower numbers of
Salmonella on shells of agar-filled eggs coated with the 2% chitosan at
the end of storage compared to the numbers on uncoated eggs, could
have caused the lower trans-shell penetration
