Antifreeze and Engine Coolant Gets Bitter Nationwide

The Humane Society Legislative Fund and Consumer Specialty Products Association jointly announce an agreement to voluntarily add a bitter flavoring agent to antifreeze and engine coolant manufactured for sale for the consumer market in all 50 states and the District of Columbiato prevent animals and children from being poisoned by the sweet-tasting liquid. Poisoning occurs because animals are attracted to the sweetness of antifreeze and engine coolant, which inadvertently spills in our driveways or is left in open containers in garages.


“Partnering with the Humane Society Legislative Fund in passing these laws in 17 states has shown by finding compromise and working together we can develop sound public policy. It is vital that consumers continue to read the labels and follow label instructions on the proper use, storage and disposal of antifreeze.Today, all major marketers are placing the bitterant in antifreeze in all 50 states,” said Phil Klein,executive vice president, legislative and public affairs for CSPA.


HSLF estimates range from 10,000 to 90,000 animals poisoned each year after ingesting ethylene glycol, the highly toxic substance used in auto antifreeze and coolant. Ethylene glycol’s sweet smell and taste make it attractive to animals as well as children. The manufacturers are adding bitter-tasting denatonium benzoate to antifreeze and coolant sold directly to consumers across the country.
