I stop treating with fumagilin in 2010 basically for 4 reasons

1.-  Fumagilin is a human need antibiotic
2.- I got mixed results in my yards and literature (do not ask me for the
exact reference) said that under healthy bee condition it did more bad than
good.
3.- Better to have healthy (ie low varroa)  fat bees than to give a
contradictory concoction.
4.- It is F***g expensive.

The above been said, after a long talk with the main  "advisors (that) have
made (chilean) beekeepers
very fearful of *Nosema ceranae I came to the conclution that some use of
Fumagilin is need when you must recover from doing bad or wrong beekeeping.
Unfortunatelly for you I reported that conversation in spanish here
http://apiaraucania.blogspot.com/2012/11/conversando.html
and later on I ask Mariano Higes which was his opinion to my writing and
his comments are here (again in spanish)
