Instant coffee products sold at Dollar General stores nationwide have been recalled due to the "potential presence of glass," according to the company. Dollar General has voluntarily recalled three lots of its 8-ounce Clover Valley Instant Coffee sold in 48 states, the company said in an announcement posted by the U.S. Food and Drug Administration.

The coffee was sold in 47 states and Puerto Rico between July 9 and July 21. Dollar General didn't say how many containers were included in the three lots of coffee that were distributed, or how many were sold before the recall went out.

Dollar General is voluntarily recalling instant coffee that has the potential to have glass in it. According to a U.S. Food & Drug Administration announcement, Clover Valley Instant Coffee is being recalled after a customer notified Dollar General of the possible issue.
