In this study, we focused on fattening broiler and turkey farms to test the hypothesis as to whether their (historical) AMU levels in previous years show significant (long-term) effects on the current AMR levels in E. coli as indicator bacteria for AMR in the farm environment (regardless of AMU and AMR in the previous production phases), while accounting for the potential short-term effects of current AMU and other variables of interest, such as farm size and season.

Litter samples from 35 broiler farms and 35 turkey farms were collected for antimicrobial susceptibility testing of E. coli. The broiler farms were sampled longitudinally four times, once every season, starting in June 2019 and ending in August 2020 (spring: March-May; summer: June-August; autumn: September-November; winter: December-February). Sampling of broilers occurred at ∼30 days of age.
