They are a human irritant because of their venomous setae (hairs), which can cause skin irritation and asthma. The moths are widely distributed in central and southern Europe, and are occasionally found as far north as Sweden. In the southern countries of Europe the populations are controlled by natural predators, but these predators do not exist in northern Europe. Their range is expanding northward, possibly or partly as a result of global warming. The moth now has an established population in the
Canadian Science Centre for Human and Animal Health the only facility in Canada operating Containment Level 4 (CL4) laboratories and is believed to be the first in the world to have both human and animal Level 4 laboratories under one roof. Level 4 laboratories are designed to allow scientists to safely handle the most serious infectious agents. Their design, construction, and engineering controls safeguard against the release of any infectious material. Both NML and NCFAD operate critical diagnostic testing programs relied on across the country. These programs protect human health, animal health, and international trade. Staff also undertake cutting-edge research to advance scientific knowledge, improve diagnostics and develop
