Exploring the Use of Probicon L28 and BIOPLUS 2B As Direct-Fed Microbials To Reduce Salmonella and Shiga Toxin-Producing Escherichia coli in Market Hogs

---

Abstract

Market hogs are often a critical reservoir for Salmonella and Shiga toxin-producing Escherichia coli (STEC). Thus, these pathogens can be found in the environment of swine farms. Salmonella has also been recovered from market hog lymph nodes, which can pose a risk to pork products. Intervention application at the abattoir is important; however, a need exists for identifying an effective intervention(s) that reduces pathogens in market hogs pre-harvest to reduce the pathogen burden entering the abattoir. Probiotics, especially lactic acid bacteria, have been heavily researched in cattle as pre-harvest interventions, particularly for E. coli O157:H7 control. BIOPLUS® 2B, which is comprised of Bacillus subtilis and Bacillus licheniformis, is currently the most common probiotic used in the swine industry to establish microflora of the gastrointestinal tract and aid in healthy animal performance. Lactobacillus salivarius L28 (Probicon L28) is patented as a food safety intervention that is included in animal diets to reduce pathogens. Because there is a need for effective pre-harvest interventions in the swine industry, the objective of this study was to investigate BIOPLUS® 2B and Probicon L28 as pre-harvest interventions to reduce Salmonella and Shiga toxin-producing Escherichia coli in market hogs.
