Means in the same row followed by different letters are significantly different (p < 0.05)

¹To allow log transformation of data when no SE colonies were detected following direct plating, but SE was detected after enrichment, a count of 5 CFU/egg was assigned. When there were no colonies by both direct plating and enrichment, a count of 1 CFU/egg was assigned
