Dog and Cat Owners - Arthur Dogswell LLC has announced a voluntary recall of certain Dogswell and Catswell chicken or duck jerky treats due to potential contamination with unapproved antibiotics. The vast majority of these products were distributed via retail stores and mail order companies before March 1st, 2013. These products may contain trace amounts of an antibiotic residue that has not been approved for use in the United States. According to a letter posted by Dogswell, the affected jerky treats were made in China. There is no evidence that products containing trace amounts of this antibiotic pose a health risk for pets or humans. The company is taking this action after learning this week that the New York State Department of Agriculture and Markets (NYSDAM) found trace amounts of the additive during a routine product sampling. The withdrawn products include Chicken Breast and Duck Breast jerky marketed under the following brand names: Breathies Happy Heart Happy Hips Mellow Mut Shape Up Veggie Life Vitality Vitakitty The affected products contain a Best Before (or earlier) date of January 28th, 2015. No other products are affected. Additionally, Chicken Breast and Duck Breast jerky products with a Best Before date of January 29th, 2015 and later have been fully tested for these antibiotics and are not affected. The Best Before date can be found stamped in black ink on the back of the package on the bottom right hand side.
