Interpretive Summary:

Technical Abstract: Sodium chlorate effectively reduces the numbers of gram-negative pathogens in gastrointestinal tracts of live animals when administered in the 24 to 72 hour period prior to slaughter. It is believed that a chlorate-based product could be a cost-effective and efficient method to reduce the contamination of carcasses during animal processing. The purpose of this study was to determine a dose of sodium chlorate in swine that would result in chlorate residues below FDA CVM-estimated safe tissue concentrations. Three sets of swine (one barrow and one gilt each) were dosed with 20, 40, or 60 mg/kg sodium [36Cl]chlorate dissolved in drinking water during a 24-hour exposure period. Animals were slaughtered after a 24-hour withdrawal period and edible tissues were removed and analyzed for chlorate content. Total radioactive residues and chlorate residues in edible tissues and excreta of swine will be reported.
