NBC NEWS- The Boston Beer Company is urging consumers to take a close look at any unopened bottles of "Sam Adams" beer.

Thousands of 12 ounce glass bottles are being voluntarily recalled because they may contain glass fragments.

The affected bottles are embossed with the letter "N" followed by the number "35" and the letters "OI".

They were bottled in the company's Cincinatti brewery using bottles provided by an outside supplier.

So far there have been no reports of illness or injury.

Consumers who have purchased the bottles included in the recall are urged to contact the company for a full refund.
