Kentucky was observed in non-diseased turkeys. ► Clonally related isolates were also found in foods and municipal savage. ► Multiresistance covered antimicrobials critically important for human treatment. ► The first animal-related, ESBL-producing (CTX-M) Salmonella was reported in Poland. ► The detected epidemic in turkey flocks may reflect on the adverse food safety effect.
