Abstract
This chapter presents a study investigating whether meat, offal or milk from cattle consuming corynetoxins (CT) present a risk of causing secondary toxicity. In this study, clinical annual ryegrass toxicity (ARGT) was produced in cattle by feeding them toxic ryegrass (Lolium rigidum), and then meat, offal and milk were collected from these animals. These products were then fed to pigs and rats for 117 and 196 days, respectively, and then these animals were euthanized and liver microsomal GlcNAc-1-P transferase activities were determined. The results showed that all pigs and rats appeared healthy throughout the experiment. No inhibition of liver microsomal GlcNAc-1-P transferase activity was observed in both pigs and rats fed the potentially contaminated meat, offal or milk. It is concluded that it is highly unlikely that secondary toxicity will result from the consumption of meat, offal or milk derived from livestock that have ingested CT.
