Flea Collars’ Hazards

Dangerous carcinogens and neurotoxins discovered in everyday flea and tick collars.

Protecting your family and animal companions from fleas and ticks sounds like a great idea. Upping their risk for cancer and neurological damage, on the other hand, sounds like, well, not such a great idea. However, a startling new study suggests the two may be intrinsically linked. In fact, levels of propoxure and tetrachloryinphos, known carcinogens and neurotoxins, were found at a level 1,000 times higher than the EPA has set for children. The Natural Resource Defense Council discovered hazardous chemical residue left on animals’ fur following flea and tick collar use, even two weeks after removal. These toxins pose an even greater risk to youngsters, since their nervous systems haven’t fully developed. Our advice? Either live with the pests or opt for a natural alternative!
