Escargot in cargo: Invasive giant African snails detected more than 28 times at borders

Australian biosecurity officers are alarmed by a boost in invasive 20-centimetre-long snails obstructed at the border checkpoints.

The giant African snail is among the world’s worst invasive insects and was detected 28 times in 2015 and 3 times in the previous month at various places throughout the nation.

“There has been a bit of disruption and change in terms of container movement patterns and the ability of countries to apply their normal inspection protocols as well, and that is possibly one reason why we’re seeing an increase,” she stated.
