In our re-evaluation, which specifically looked at the ready-to-use bait, which is a diluted and formulated fashion of strychnine, there were still concerns about the effects of that level of strychnine both on human health and on non-target species. If a 0.4% ready-to-use bait presents challenges, I think it's pretty clear that a concentrated form of strychnine presents even higher levels of concern for human health and the environment.
There is discussion--and we've had discussion with the Saskatchewan Association of Rural Municipalities--about presenting an alternative aluminum phosphide known as Phostoxin as an alternative.
I know that there have been some concerns raised about the effectiveness of the strychnine ready-to-use bait, so we've been working with farmers and the provinces of Alberta and Saskatchewan on alternatives. This one, Phostoxin or aluminum phosphide, has been presented as an alternative, and I think there's interest in looking at it.
