The AP (via Business Week) reports that the company Owen-Illinois Inc. has confirmed that they made the 12-ounce glass bottles involved in the Sam Adams recall:
Owens-Illinois Inc. said Tuesday it is investigating glass bottles it made for a brewery after the brewery's voluntary recall of those bottles.
Owens-Illinois confirmed it made the bottles in The Boston Beer Co.'s recall of select 12-ounce bottles of Samuel Adams beer...
...On Monday, Boston Beer said in a news release that its "precautionary recall comes after routine quality control inspections at the company's Cincinnati brewery detected defects in certain beer bottles, manufactured by a third-party glass bottle supplier that might cause small bits of glass to break off and possibly fall into the bottle."
Sam Adams released a statement regarding the voluntary recall:
During a routine bottle inspection at one of our breweries, we detected possible defects in a small percentage of bottles resulting in the random presence of bits of glass, most the size of grains of sand, but some small slivers in some bottles as well. Based on this sample, we quickly began testing bottles of Samuel Adams at all of our breweries and identified that the problem appeared to be isolated to a single glass plant of the five that supply us.
We assembled a panel of food safety, medical and packaging experts including a medical doctor who have thoroughly evaluated the samples. People who bite or swallow a fragment could possibly be injured. While the possibility of injury to an individual consumer is very low and the Company has had no reports of any injury, we do know that the risk is not zero, so we are voluntarily recalling all products in bottles from this specific glass plant that we believe could possibly be affected. While we believe that the number of bottles that actually contain glass is significantly less than 1% of the bottles we are recalling, we are taking this measure to protect the safety of our drinkers.
