As you know, the last two pet food recalls for two much Vitamin D which were Blue Buffalo dog foods and then more recently Mazuri foods for rodents and other animals wound up widening to more of their foods, so if you are using a Purina food it will important to know if this recall is due to a product used in more foods in the production facility or only in certain types of foods or certain production facilities. Currently the Well Solve and food fish lines are the ones involved, so if any home food people here give fish to their ferrets or dogs then the same consideration exists as for the Mazuri rodent foods since Vitamin D is fat soluble so will stick around in increased levels in the animals fed it for a while. http://www.fda.gov/Safety/Recalls/ucm311983.htm?source=govdelivery Should time allow, I will have to check the past melamine recall, but IF memory serves Mazuri and Purina, like Blue Buffalo, MIGHT a history of using ingredients imported from China (a way to reduce costs especially if there are other huge expenses like a lot of advertising), but you can check the 2007 list on that score. I know that Blue Buffalo has that history, but not if the other two do so you should check this since I lack time: http://www.accessdata.fda.gov/scripts/petfoodrecall/ In dogs and in ferrets too much Vitamin D3 can result in hypercalcaemia which winds up causing calcium deposits in organs such as the heart and kidneys. If stopped soon enough those resolve, but if not stopped soon enough kidney failure results if the levels are too bad. The Mazuri recall was recent so this leads to the question of whether the origin was the same, perhaps an ingredient or an additive that winds up changing to D3 in the body. That is what happened with the Blue Buffalo foods when they were studied at Michigan State's DCPAH by Dr. Kent Refsal. When ingredients that can release or change to D3 in the body are used then the added D vitamin level has to be adjusted accordingly but they were not. Here is the FDA Veterinary section: http://www.fda.gov/AnimalVeterinary/default.htm and pet food recalls: http://www.accessdata.fda.gov/scripts/newpetfoodrecalls/ Gads, this -- just popped up on the website while I was creating this post -- shows more Mazuri foods recalled -- fish, bird, frog, more rodent foods and loads more foods now -- due to high D levels, so whatever they put in their wolf diet, their rodent food, primate foods, etc. that created the high D levels is also in their fish foods. It makes a person wonder which other foods may be affected, and if the widening will work in the opposite direction for the Purina foods with the fish ones found first but maybe rodent foods and other foods also having the same problem ingredient: http://www.fda.gov/Safety/Recalls/ucm311992.htm So use caution w foods from these places and if you feed your own or pet store rodents, chicks, fish, frogs, etc. to ferrets know that they might deliver too high levels of D to the ferrets. Those who feed grocery store meats to ferrets need to follow the recall lists for those foods which you should do at http://www.fda.gov/Food/default.htm AND at the USDA recall website since meats, poultry, fish, etc. have almost constant recalls going on. Ferrets have the same problems with shiga toxin producing E. coli as humans and like us can die or have permanent kidney damage. They are more resistant to salmonella than we are but when they get it they can be just as ill and just as hard to treat. (BTW, new regulations are gradually going into place to improve egg safety on that score with most of the changes happening in next 4 years or so to give farms and boxing facilities time to improve and to spread associated costs over the years but some start now. I do not know if new regulations to make poultry itself safer are coming, too, but remember that a study a few years ago in grocery stores in PA found something like 30% of the chicken to have high salmonella levels.) There are also other forms of food poisoning ferrets can get just as we can. Sukie (not a vet) Ferrets make the world a game.
