A Denver pet treat maker is recalling dozens of different products -- from chicken jerky and pig ears to buffalo hearts -- because they might be contaminated with salmonella. 

It's the third recall since the fall by Kasel Associated Industries and covers all products manufactured at the Colorado facility from April 20 through Sept. 19, 2012. The firm previously declined to recall its treats, despite urging from the federal Food and Drug Administration. 

The recall is not related to the FDA's ongoing investigation into pet illnesses and deaths tied to chicken jerky pet treats made in China.

The Kasel recall includes several popular brands, including items sold at Costco. Kasel is recalling Boots & Barkley, BIXBI, Nature's Deli, Colorado Naturals, Petco and Best Bully Stick items. The products include best buy dates through Oct. 3, 2014. 

The treats could be contaminated with salmonella bacteria, which could lead to illness in pets -- and in people who come in contact with the products or pets who've consumed them. Symptoms of salmonella infection in pets include lethargy, diarrhea or bloody diarrhea, fever and vomiting. Some pets will have decreased appetite and no other signs. 

Similar symptoms can appear in humans. Salmonella infection typically causes illness that lasts only a few days, but in young children, the elderly or those with weakened immune systems, the infection can be severe and require hospitalization. 

The list of recalled products includes 48 separate items. For the full list, click here.
