Toxic Heavy Metal Levels In Pet Foods

kibble (Custom)In early 2011, Spectroscopy Magazine published the shocking results of labratory testing of pet foods for heavy metals.  The paper revealed  there were TOXIC levels of lead, mucury and even nuclear waste in many of the pet foods tested

The published scientific evidence that some commercial pets foods contain a lot more than the advertised choice cuts of meat and fresh vegetables.  Some pet foods contain toxic levels of arsenic, lead, mercury, and even nuclear waste.

Quoting the Paper “Analysis of Toxic Trace Metals in Pet Foods Using Cryogenic Grinding and Quantitation by ICP-MS, Part 1? published in the January 2011 Spectroscopy Magazine…

“For this investigation 58 cat and dog foods were bought from local stores or donated by the authors and other pet owners. The samples consisted of 31 dry food and 27 wet food varieties. Of the 31 dry foods, 18 were dog food and 13 were cat food samples. The wet foods comprised 13 dog food and 14 cat food samples, representing pet food contained in cans and pouches.”

“Pet food prices ranged from the “bargain” store foods priced at $0.02/oz to gourmet or specialty foods purchased from pet suppliers priced at $0.42/oz. Three canned foods for human consumption were tested, including tuna fish, sardines, and chicken, which were sampled for comparison and control purposes.”

“The analysis of all the pet food samples showed that the highest concen¬trations of toxic elements were found in the dry foods of both cats and dogs. Out of the elements studied, dry food had the highest elemental content for 13 of the 15 elements examined. Dog food had the highest result for nine of the 15 toxic elements and cat food had the highest concentration for six of the 15 elements.”

“The dry dog food contained the highest concentrations of the following elements: beryllium, cad¬mium, cesium, antimony, thorium, thallium, uranium, and vanadium. The wet dog foods contained lower concentrations of the toxic elements studied than the dry dog foods.  The dry cat foods contained the highest results for five of the 15 elements including arsenic, cobalt, molybdenum, nickel, and lead.  The wet cat foods showed the overall lowest concentrations of the toxic elements studied than any of the other pet foods studied.” 

“The presence of several other elements in some of the pet food samples was unexpected. Uranium, beryllium, and thorium are often associated with nuclear energy and mining. As stated earlier, concentrations of over 500 ?g/kg of uranium were found in several of the dry dog food samples. A few of the dry cat food samples had concentrations of over 200 ?g/kg of uranium. In these samples of high uranium concentrations, there were also found to be the highest concentrations of both beryllium and thorium.”

Part II of the article examined in detail the data and calculated the toxic metal exposure levels of the pets on a daily basis, based on typical size portions. It also looked for a correlation with the cost of the individual pet foods. The exposure levels were then compared with EPA and WHO risk assessment values generated for the human population, scaled to the weight of a medium-sized dog or an average-sized cat.

There are no FDA guidelines for toxic metals in pet food.

Here we are in February 2013, has anything been done about these findings?   How many of you even knew of these findings two years ago???

What’s the answer?

A species appropriate – RAW meat, bone and organ diet such as our dogs (and cats) are designed to eat and thrive on of course! 🙂
