Here is a link to a study out of the Netherelands about ivermectin residuals in eggs after oral dosage of ivermectin in the feed. It also talks about it in liver & kidney meat. I'm adding this in case others want to reference it. The abstract gave a nice summary I thought. FYI: An mcg (a microgram) is one thousandth of a milligram. To convert micrograms to milligrams, divide by 1000 e.g. 5600 mcg = 5.6 mg http://www.euroresidue.nl/ER_IV/Contributions I-Z/keukens 678-682.PDF And here is a link to a site that talks about the use of ivermectin in humans. This is not comprehensive, obviously, but still interesting. http://www.drugs.com/cons/ivermectin.html I found these links through google searches for my own information and thought I'd share.
