Accidental consumption of rat poison such as bromadiolone can happen in pigs, and is concerning for animal welfare, food safety and economic reasons. Blood and feces were sampled after pigs had been given a high or low oral dose of bromadiolone, as well as tissue samples. Blood and feces samples showed bromadiolene, meaning they could potentially be used by veterinarians to determine if pigs have been exposed. Liver samples showed bromadiolone exposure in both doses, and high doses led to muscle tissue also showing exposure. The results can help develop sampling standards after suspected exposure, and to determine withdrawal times.
