For those who don't think the FDA/CVM has done enough testing to determine what's wrong with these jerky treats this is what they have tested thus far.
We conducted bacterial, compositional and toxicological analyses, and evaluated irradiation effects on glycerin; however, each sample did not necessarily undergo all four analyses. The specific types of tests we conducted on jerky treat products include:
• Microbiological Testing
o Bacterial culture for Salmonella
o Bacterial enterotoxin
o Mold and yeast culture
o Mycotoxin
• Compositional Testing
o Physical characteristics evaluation
o Composition with glycerol content
o Vitamin D content
o DNA analysis
• Chemical Toxicology Testing
o General screens for toxic compounds: restricted list
o Metals: various heavy metals
o Glycols: diethylene glycol-DEG; ethylene glycol-EG; propylene glycol-PEG; dihydroxyacetone (DHA); and 1,3 Propanediol
o Glycerin metabolites: glycolic acid, diglycolic acid, and lactic acid
o Sugar alcohols: xylitol (added in 2013), sorbitol (added in 2013), glycerol
o Other organics: hexachlorobutadiene, paraquat, aristolochic acid, and oxalic acid (added in 2013)
o Antibiotics: gentamicin, tetracycline degradation products, sulfonamides (sulfaclozine, sulfaquinoxaline), trimethoprim, enrofloxacin, tilmicosin; several samples also tested for: sulfamethoxazole, sulfamethazine, sulfadiazine, sulfathiazole, sulfanilamide, sulfadimethoxine, sulfasoxizole, chloramphenicol, and gatifloxacin (both added in 2013)
o Drugs: monensin, quinocetone, and additional forensic drug screen (list-restricted information)
o Biogenic amines: putrescine, cadaverine, histamine, agmatine, spermidine, and spermine
Phorbol esters: Jatropha curcas toxins
o Additives/preservatives: nitrites, sulfites
o Tanning agents: tannic acid and gallic acid
o Flavoring agents: monosodium glutamate-MSG (added in 2013), malic acid, maleic acid, methyl-4-pentenoate (added in 2013), and fumaric acid (added in 2013)
o Illegal dye agents: Auramine, Bixin, Butter Yellow, Fast Garnet, Metanil Yellow, Orange II, Orange Oil SS, Para Red, Rhodamine B, Sudan Black B, Sudan I-IV G, Sudan Orange, Sudan Red 7B, Sudan Red B, Sudan Red G and Toluidine Red
• Evaluation of Jerky Treat Irradiation
o Furan analysis
o 2-dodecylcyclobutanone (2-DCB)
