Australia mulls mouse plague controls
The Australian Pesticides and Veterinary Medicines Authority (APVMA) is considering an application from farmers for an emergency use permit to allow on-farm mixing of the rodenticide, zinc phosphide, with grain to control a plague of mice in some states. The farmers filed their request because of concerns over shortages and costs of a formulated zinc phosphide product, the APVMA points out. The Authority is concerned that on-farm mixing poses health risks to operators and bystanders and says that it would need “extensive data from reputable studies” to demonstrate that those risks could be managed. It would have fewer concerns if regional bait mixing stations were employed, the APVMA notes.
