Warning: Check Lot number Biotene UNSAFE before 2010
on July 2, 2012
(Edit to add on July 11, 2012) I would give this 5 stars, but I DO want to bring a pet owner's attention to the lot number. The lot number is the top number on the bottom of the bottle and should read after 4 2010. You will understand this when you look at the bottle.
PLEASE check your lot number to make sure your product was manufactured AFTER 2010. The Propylene glycol was REMOVED from the product in 2010.
I just received notice that the Biotene Drinking Water Additive contained Propylene glycol which is considered an adulteration of the cat food and a violation of the Federal Food, Drug, and Cosmetic Act.
There are many warnings in numerous searches and all conclude it is not safe for animal use.
"Animals - Propylene glycol is an approved food additive for dog food under the category of animal feed and is generally recognized as safe (GRAS) for dogs. Similarly, propylene glycol is an approved food additive for human food as well. The exception is that it is prohibited for use in food for cats because of a species-specific reaction in the body, as noted in 21 CFR 582.1666.
Veterinary data indicate that propylene glycol is toxic to dogs with a 50% chance of being lethal at doses of 9mL/kg, although the figure is higher for most laboratory animals (LD50 at levels of 20mL/kg).
However, propylene glycol may be toxic to cats in ways not seen in other animals. The U.S. Food and Drug Administration has determined that its presence in or on cat food has not been shown by adequate scientific data to be safe for use. Any such use is considered an adulteration of the cat food and a violation of the Federal Food, Drug, and Cosmetic Act."
