How Do Chickens Get Salmonella, Anyway?

Apr 25, 2023

By Andrea Etter

I don’t think I’ve done a post on this before, so here goes… Ever wonder where chickens get Salmonella from? It turns out there are a lot of options. In our research it seems adults most likely get Salmonella from the environment, feed, wild animals/birds, or each other (yes, feed can contain Salmonella–probably from birds/mice/other animals pooping in it). Chicks, however, often arrive from hatcheries already infected, which may mean they are born infected with it (option A). Either way, it can get you sick. Fortunately, research on commercial birds indicates that many/most infected chicks clear Salmonella by adulthood.

Video: Genetics Behind Swine Resilience - Dr. Jenelle Dunkelberger

In this episode of The Swine it Podcast Show Canada, Dr. Jenelle Dunkelberger, geneticist at Topigs Norsvin, explains how genetics can improve disease resilience in pigs. She explores how resilience differs from resistance, the role of genetic variation, and how breeding strategies can enhance health and performance under disease pressure. Dr. Dunkelberger also covers practical applications and future implications for swine production. Listen now on all major platforms!

"Controlled experimental trials confirm that differences in mortality and performance under disease pressure are linked to genetic background, even when environmental conditions remain consistent."

Meet the guest: Dr. Jenelle Dunkelberger / jenelle-dunkelberger-9200ab86 is a geneticist at Topigs Norsvin, where she leads the Global Health and Behavior Research Platform. She earned her PhD from Iowa State University, focusing on host genetics and disease response in pigs. Her work centers on improving swine health and performance through genetic selection for resilience and behavior traits.
