Why Does Tylenol Kill Snakes?
.
By Ross Pomeroy - RCP StaffJanuary 23, 2020
The headline seemed too strange to be true, the animal equivalent of the 82nd Airborne parachuting behind enemy lines in Normandy:
"Two thousand mice dropped on Guam by parachute — to kill snakes."
Back in 2013, in an attempt to quell the out-of-control population of invasive brown tree snakes which was devastating Guam's local birds and mucking with electrical infrastructure, the United States Department of Agriculture's (USDA) Wildlife Service bombarded targeted areas owned by the U.S. Government with dead mice, each armed with 80 milligrams of acetaminophen, the active ingredient in Tylenol. The idea was that the snakes would eat the mice and die.
Unlike other attempts to combat invasive species, which regularly backfire, this one seemed to work pretty well. The acetaminophen"mice bombs" didn't harm other animals and killed the invasive snakes within 24 hours of consumption. More air drops are planned.
So why does 80 milligrams of acetaminophen – just a quarter of the amount in a regular Tylenol pill – kill a snake while it would take 500 times more to kill a similarly-sized mammal? That question was the subject of a recent study published to the journal Scientific Reports.
As evidenced in prior research, as little as 40 milligrams of acetaminophen can be acutely toxic to any reptile, not just snakes. USDA wildlife scientists Tom Mathies and Richard E. Mauldin were curious why. A previous study hypothesized that reptiles lack the enzymes needed to metabolize acetaminophen. Over just a few days, elevated levels of acetaminophen can kill liver cells. However, in only a matter of hours, they can convert an organism's oxygen-carrying hemoglobin molecules to methemoglobin, which cannot transport oxygen. The body's cells are thus starved of oxygen, resulting in death...
