Eggs are valuable foods produced by healthy laying hens that could harbour antimicrobial resistant (AMR) bacteria from animal faeces on their shells. To test the dynamic of AMR faecal bacteria in a comercial laying hens farm from day-old chicks to pullets and adult laying hens. One commercial batch was sampled six times along a year during the laying cycle, taking ten faecal samples per sampling. Samples where pooled, diluted with buffered peptone water and spread onto MacConkey agar plates incubated at 37 °C for 20-24 h. Ten presumptive E. coli colonies per sampling were picked, idenƟfied and tested using EUVSEC plates. Our data show that faecal AMR bacteria decrease during the production phase, and so the probability of cross contamination of the eggs shell is negligible
