After detecting trace amounts of an unapproved antibiotic in a batch of chicken jerky treats, Dogswell has voluntarily withdrawn some of its products from the market.

Its sister company, Catswell, has also recalled certain products as a preventive measure.

According to a letter to consumers posted on the Dogswell website, the New York State Department of Agriculture & Markets detected trace amounts of an antibiotic in a sample of Dogswell Happy Hips Chicken Breast Jerky. Dogswell said that although the antibiotic is approved for use in other countries and trace amounts of the antibiotic have not been shown to pose a health risk to animals or humans, the antibiotic is unapproved in the U.S. and therefore prompted the voluntary recall.

The following Dogswell and Catswell chicken breast and duck breast jerky products that are labeled with a "Best Before" date of Jan. 28, 2015, or earlier have been voluntarily recalled:

• Breathies
• Happy Heart
• Happy Hips 
• Mellow Mut
• Shape Up
• Veggie Life
• Vitality
• Vitakitty

Products with a "Best Before" date later than Jan. 28, 2015, and any other products still on the market are safe for pet consumption, the manufacturer said.
