Dr. Ken Macklin and Dr. Sarge Bilgili from Auburn University recently completed a research project where they studied the ability of Salmonella enteritidis (SE) and Salmonella heidelberg (SH) to colonize and persist in various tissues and organs of broilers inoculated by various routes and at different ages.

They found that feeding broilers continuously with feed contaminated with a low level of either SE or SH resulted in every bird being contaminated.

Additionally, they found that aerosol exposure was efficient in establishing colonization of SE and SH in broilers.


Their results also showed that broilers could potentially become colonized by Salmonella at any time during their lives.
