Salmonella exposure to consumers from eggs has been a decades-long concern. Richard Gast, poultry research microbiologist at USDA’s US National Poultry Research Center in Athens, Georgia, has developed two research projects to gain more perspective on Salmonella Enteritidis in cage-free layer housing.
The shift to cage-free layer housing opened the door to poultry diseases that disappeared during the years of cage housing. At the Devenish Symposium held during the 2025 PEAK conference, Dan Wilson, DVM, Wilson Vet Co., discussed the return of several diseases from the past that affect today’s egg layers.

Breeding birds for efficient cage-free production requires developing healthy hens that lay an egg every day for 100 weeks and possibly up to 200 weeks in the future, reported Sijne Van der Beek, PhD, chief technology officer, Lohmann Breeders, The Netherlands.
