A: No evidence of any poisonous, infectious or disease-causing effects were
found. In
inhalation tests with Btk, there were no mortalities and the Btk was shown to
have a low
pathogenic potential. Feeding, skin, breathing, and eye irritation animal
studies were also carried
out with Thurisave-24. No toxic effects were seen when significant quantities of
Thurisave-24
were fed or inhaled.
