Our objective was to summarize the current research on the effect of various washes, rinses, sprays, and steam against Salmonella on pork carcasses or parts of pork carcasses with the skin on. In January 2015, we searched the scientific literature…
A study to assess the tissue residue depletion profile of ampicillin in cull sows and its association with plasma, oral fluid and urine ampicillin concentrations
The use of more stringent penicillin detection methods in edible tissues at processing and a zero tolerance for the presence of detectable residues in some territories has resulted in an increase in penicillin residue violations at slaughter and caused pork…
Evaluating strength, sharpness, and detection of swine-use hypodermic needles
A previous study (circa 2000) investigated swine-use hypodermic needle strength and detection. At that time, needle detection equipment available at processing plants was entirely magnetic-based. Since this original study, processing plants have added X-Ray based technology. The purpose of this…
Further Characterization of Salmonella and Campylobacter Isolates from NARMS Study
The primary objective of this research was to examine the potential impact of normal lairage practices on Salmonella, Campylobacter and E. coli antimicrobial resistance patterns in swine following evisceration in an abattoir environment. Fecal samples were collected upon arrival at…
Determination of seroprevalence to Toxoplasma gondii in the U.S. National swine herd
Molecular Basis of Salmonella Competition in Broth Culture
Salmonella remains an extremely important bacterial pathogen to the swine industry. It is a significant pathogen affecting swine health and also represents one of the most important foodborne pathogens affecting people. A key aspect of Salmonella control is the use…
National Prevalence of Salmonella Contamination in Retail Ground Pork
Salmonella is a foodborne pathogen that may be associated with meat products. The goal of this project was to determine the prevalence of Salmonella in ground pork at retail, and to evaluate factors that may be associated with its prevalence.…
Determining the Prevalence and Antimicrobial Susceptibility of Salmonella Serovars Isolated from U.S. Retail Ground Pork
Salmonella is a foodborne pathogen that may be associated with meat products. The goal of this project was to determine the prevalence of Salmonella in ground pork at retail, and to evaluate factors that may be associated with its prevalence.…
Salmonella serovar distribution and persistence in finisher sites
There is a paucity of data explaining the persistence ofSalmonella serovars on swine farms. In this study, we evaluated 900 pigs from 18 cohorts of finisher swine over a 3.5 year period in one production company to understand the distribution and…
National Animal Health Monitoring Survey for Toxoplasma gondii and Trichinella spiralis
The United States Department of Agriculture (USDA) initiated the National Animal Health Monitoring System (NAHMS) in 1983 to collect, analyze, and disseminate data on animal health, management, and productivity in U.S. domestic livestock populations. The purpose of this study was…
