A Survey of Salmonella Serovars and Most Probable Numbers (MPN) in Rendered Animal Protein Meals: Inferences for Animal and Human Health
Abstract
Salmonellae are resourceful and adaptive organisms that infect a broad range of diverse hosts. Serovars of the genus
were first isolated in a poultry mash in 1948, thus establishing a need to assess the pertinence of Salmonella organisms in
animal protein feed ingredients. A random sampling scheme was established to evaluate the Salmonella population level
by three-tube most probable numbers (MPN) analysis and serovar identity over a period of one year. The results provide
evidence of the limited relatedness of animal protein meals in the complex cycle of feed contamination and likely
subsequent transmission of disease to animals or humans through the feed chain.
