Toxic Bait Spread Closes School in Mouse-Plagued Morawa

A severe mouse plague has forced the closure of the Western Australian College of Agriculture at Morawa, highlighting the devastating impact of the rodent infestation on the Wheatbelt region. The ABC Australia report details how the use of an unapproved toxic bait, zinc phosphide, on the school campus led to its immediate shutdown, sending students home and raising serious health concerns.

The situation underscores the extreme measures being taken to combat the plague, with farmers resorting to potent baits like 'Mouse Off' (zinc phosphide) typically reserved for grain paddocks. The fact that these baits were used at the school, a residential and educational facility, points to a breakdown in protocol or a desperate response to an overwhelming pest problem. The article clearly states the risks associated with zinc phosphide, noting its toxicity and the potential release of poisonous phosphine gas, especially when wet, making its use in enclosed or residential areas dangerous.

From an Australian perspective, particularly in rural areas like Morawa, mouse plagues are a recurring and destructive phenomenon. They not only cause significant agricultural losses but also disrupt community life, as seen with the school closure. The report's focus on the Department of Health's assessment of low risk to staff and students, while reassuring, does not diminish the severity of the incident. It reflects the practical challenges faced by regional communities in managing such widespread pestilence.

The closure of the agricultural college, which serves as a vital training ground for young farmers, is a significant blow. Students are being sent home or to alternative accommodation, disrupting their education and practical training. The deep clean undertaken by the Department of Education is a necessary step, but the underlying issue of the mouse plague and the appropriate use of control measures remains a critical concern for the entire region.
