I know I keep a supply of this product on hand for litters and other breeders do too. Here is what the FDA says:
Johnson & Johnson • Merck Consumer Pharmaceuticals Company (JJMCP) is voluntarily recalling approximately 12,000 units of Infants’ MYLICON® GAS RELIEF DYE FREE drops (simethicone-antigas) non-staining sold in 1 oz. plastic bottles that were distributed after October 5, 2008 nationwide. The company is taking this action in consultation with the U.S. Food and Drug Administration (FDA). Although the potential for serious medical events is low, the company is implementing this recall to the consumer level as a precaution after determining that some bottles could include metal fragments that were generated during the manufacturing process.
