Toxic Flea Collars

Did you see this warning about flea collars the other day?


Flea collars banned in France over suspected human health risks are still being bought by 1000s of pet owners.  They were removed from French shops last month after experts decided the danger – particularly to children – was too great. 

Among the collars withdrawn are those containing dimpylate (diazinon).  It is an organophosphate developed as a nerve gas during the Second Wold War.  The chemical is in Bob Martin Dog Flea Collar and Johnson’s Veterinary Flea Guard Collar for Cats. 

Diazinon poisoning symptoms include headaches, dizziness, blurred vision, nausea, vomiting, muscle-twitching, personality changes and loss of co-ordination.  In extreme cases it can cause convulsions. The Dogs Trust said “There are equally effective safer products on the market..”   Last night there were calls for Britain to follow suit and ban the cat & dog collars.    Mail on Sunday 13.5.12

Don’t use them.

  1. I am certainly do not like organophosphate pesticides such as diazinon (= dimpylate) and favour their substitution by other less toxic alternatives, both in animals and in agriculture

    But it is totally wrong to write that diazinon was developed as a nerve gas during second world war. The fact is, that it was developed in 1952 by the Geigy AG in Switzerland and from the very beginning used in agriculture and animal health, never as a lethal weapon, among other reasons, because it is not toxic enough.

    Such missleading statements will not accelerate the substitution of organophosphates because they discredit its supporters. And they are superfluous because there are enough valid and solid arguments in favour of such a substitution.

  2. Thanks Pablo, interesting comment. We can rely on the Daily Mail to exaggerate, of couse! Still a toxin however it was developed but thanks for that correction.
