Four times a year, pet bloggers band together to raise awareness
about issues critical to the welfare of the animals we love.

This special Monday Medical post is about the worrisome increase in pet food recalls over the past year.

As of July, 2012, 47 people in 20 U.S. states (plus 2 in Canada) had suffered salmonella poisoning traced back to the handling of dry pet food made in the USA.
I’ve been sitting back and reading about the vast number of pet food and pet treat recalls over the past year, but haven’t really done anything to address it on this blog, mainly because of the vast amount of exposure it's had on other blogs. I didn't feel I could add much to the conversation until now.
But a few weeks ago some information was dropped into my lap by a radiation physicist. Here’s what I was told.
The FDA imposes a limit on the amount of radiation human-grade food items may be given. It also imposes a limit on the amount of radiation given to animal feed – and pet food comes under those guidelines.
In general, the FDA allows a much lower dose of radiation to kill harmful bacteria on human grade food than it does for pet food.

| Raw eggs: allowed 5 kGy to protect from salmonella |
Frozen raw meat is allowed a bit more than eggs - 7 kGy. And again, given that there are between6 and 33 million illnesses a year in the U.S. alone1 due to microbial pathogens found in raw meats, that completely makes sense.
Yet pet food is allowed 50 kiloGray. That's ten times the FDA limit for raw eggs.

| Pet food: allowed 50 kGy to kill pathogens |
So why would pet food be allowed ten times the radiation as raw eggs and fifty times the radiation for raw vegetables?
These are significantly higher levels. The answer simply is that food is split into two categories: human grade food, and food not fit for human consumption.
The husband of an associate of mine grew up on a ranch in the Midwest U.S., and he tells a story about where their sickly and deceased animals were sent. You guessed it: the pet food plant. He said there would often be days that passed between the time they notified the pet food plant about the dead animal’s carcass and the time workers at the plant arrived to pick it up. During that time, the carcass remained exposed to the elements. That could mean high temperatures, insects – plenty of opportunity for decay and bacteria growth.

Fifty kiloGray. One can understand the need for a higher amount of radiation after hearing the rancher’s tale.
But given the rash of recalls in 2012 alone, even that doesn’t seem to be working so well, does it?
To be fair, yes, animals can handle eating things we can’t, but a cat killing a mouse and then eating it, bones and all – well, that’s a fresh kill. There's little chance for bacteria to become an issue.
After reading all this, I was very glad for the decisions I’d made regarding what our cats eat. Of the three brands of cat food served in our home, one uses human grade ingredients and another requires that its farmers and suppliers provide Letters of Guaranty stating that their meats and produce are fresh and unadulterated. The third brand has very strict protocols in place and rigorously tests for salmonella and E. coli (though to be honest, I am trying to wean a certain kitty – yes, Maxwell, I’m looking at you! – off this third one).
I understand that price can prohibit some from switching over like I have. I only have the three cats, but I know several people who rescue and/or foster animals for whom the premium pet food might be too expensive.
But I have to admit, I was intrigued to see the post by Whisppy showing how they make their own dried chicken jerky treats right in their home. So I did a little research on what it might take to make pet food – and how that might impact our budget. That’s fodder for another post (ouch, kind of a bad pun there, wasn't it?). But I can tell you that when we ran the numbers, the cost of homemade pet food looked pretty promising.
Please…tell us what you think on this issue. Are you concerned about the quality of pet foods in the U.S. and do you think the number of recalls this year is cause for alarm?

Footnote:
You’ll notice in the table below that there are two human-grade food items that exceed the 5-7 kGy limit, and those are spices and astronaut food. We figure NASA’s got a lot of special reasons for wanting their food to be especially sterile, so we’re counting that out of this discussion.
But we find it interesting that the FDA allows 30 kGy for spices, due to the extremely high incidence of molds and other bacteria found in them – especially those coming from countries known to have a higher level of contaminants.
In fact, spices are so easily contaminated that doctors will tell patients who are undergoing stem cell transplants to avoid all spices before, during and for a period after treatment, to protect them while their immune systems are weakened.
