> Recent studies show that this antibiotic may be ineffective against N. ceranae infections (38–43). There is also evidence that fumagillin is fairly toxic and causes chromosomal aberrations, carcinogenicity in humans, and alterations to the ultrastructure of hypopharyngeal glands in bees (37). Consequentially, many countries outside of the Americas (including the European Union) have banned fumagillin for agricultural use 


Thanks, Peter,  I was surprised to see that Vita Bee Health assumed the manufacturing role in Canada- Vita had a big poster announcing the comeback in the vendor area at Apimondia. But I guess the  Canadian Honey Council got behind the effort apparently at the request of concerned beekeepers.

I see no reason to use fumagillin but others have different opinions.
