Article Synopsis
- Increased focus on beef cattle spreading foodborne pathogens has emerged, but recent research has declined in this area compared to postharvest solutions.
- A study involving 3,708 cattle on different diets with direct-fed microbials (DFMs) was conducted to evaluate pathogen levels in fecal samples.
- Cattle fed Lactobacillus salivarius (L28) showed lower levels of C. perfringens, while both diets had similar E. coli O157:H7 prevalence, indicating the need for preharvest strategies to minimize foodborne risks in beef.
The purpose of the study was to evaluate the prevalence and concentration of foodborne pathogens in the feces and peripheral lymph nodes (PLNs) of beef cattle when supplemented with direct-fed microbials (DFMs) in feedlots. Fecal samples were collected from the pen floors over a 5-month period at three different feedlots in a similar geographical location in Nebraska, where each feed yard represented a treatment group: (i.) control: no supplement, (ii.
