Re: RE: Selenium problem



This may be based on government regs as much as on being conservative. There
is a regulatory limit on how much selenium can be added to feed and is not
based on animal health. A few years ago, selenium was considered a possible
carcingen. The burecrats had a problem. Don't want the animals pooping it
out into the environment. Can't add it to food animals and the animals can't
live without it. They fudged. More recent research indicates that selenium
is necessary for human health as well (but as adequate amounts exist in the
human diet, supplementation is not necessary) and that with the possible
exception of one compound, selenium is not carcinogenic. But the burecrats
haven't responded.
