Kefir has gained recent popularity for pets, but is it all it’s cracked up to be? Science says it’s iffy. The reasoning behind that is that the most common commercial kefir products either did not have the bacterial species it claimed to have, did not have adequate population of those bacteria or the products were mislabeled. Some products even had spelling errors on their packaging!
The most concerning of all was that the website and packaging of many of these products made a wide range of health claims, none of which are supported by the companion animal literature. This doesn’t mean that feeding kefir to your pets is bad per se, but it DOES mean we need to hold pet food companies responsible to safe manufacturing and food handling practices!
