Highlights
•
AMR is emerging and underestimated in food chain-linked Listeria monocytogenes.
•
Niches in food and food production environments may promote AMR gene exchange.
•
Common food chain interventions alter AMR through stress response mechanisms.
•
Increased AMR may lead to decreased control of L. monocytogenes during food production.
•
AMR acquired in the food chain may lead to failed therapeutic listeriosis treatment.
