Anti-tick medicines and aquariums
From my post on MTS dying:
I'm wondering about a slightly weird theory... 3 months ago we switched our
cat "Snicky" from Advantage to Revolution (selamectin). Both these products
are once a month parasiticides. This is a rather amazing chemical, able to
kill fleas and ticks for at least 30 days after a one spot application. I
understand that the chemical migrates along the animals fur and remains
potent for a long time. I pet Snicky daily (no choice really, she insists).
I wash my hands afterwards, but I also put them in the tank daily as well.
I wonder what a couple of ppm (ppb?) of this stuff would do to an aquarium?
Going to be real careful about this now.
So searching the web I find:
12. SPECIAL PRECAUTIONS FOR THE DISPOSAL OF UNUSED VETERINARY
MEDICINAL PRODUCTS OR WASTE MATERIALS DERIVED FROM SUCH
MEDICINAL PRODUCTS, IF APPROPRIATE
Any unused product or waste material should be disposed of in accordance
with local requirements. Selamectin may adversely affect fish or certain
water-borne organisms on which they feed. Containers and residual contents
should be disposed of along with collected domestic refuse to avoid
contamination of any water courses.
So do I start scrubbing down really well before I put my hands in the tank?
Selamectin seems so persistent that I wonder if I can get it off my hands at
all. Or am I guilty of spreading FUD (Fear Uncertainty Doubt)? Any similar
experiences/doubts about this?
