A company that supplies several Connecticut stores including ShopRite, 7-Eleven, PriceRite and Big Y with bottled water has issued a recall because one of its source springs may be contaminated with E.coli.

According to Niagara Bottling, the possibly contaminated water was produced at its Hamburg and Allentown, Pennsylvania facilities between June 10-18. Niagara issued a recall on June 20. It only affects water that says Niagara Bottling LLC on the label and has best by dates between "10 June 16 through 18 June 16."

"There have been no reports of any illness or injury related to the above mentioned products to date and finished product testing detected no contaminants or issues of any kind," Niagara said on its website. "This voluntary withdrawal is being implemented in cooperation with State and Federal Agencies." To determine if your water is affected, look at the code on the bottle. Only codes that begin with the letters A or F are affected.

"The first digit after the letter indicates the number of the production line. The next two numbers indicate the day, then the month in letters, the year, and then the time, based on a 24-hour clock," the recall notice said. For example, A610JUN15 2000 means the water was produced at Allentown on line 6, and manufactured on June 10, 2015 at 8 p.m.

Products made between 3 a.m. June 10 and 8 p.m. June 18 should not be consumed, the notice said.

"As the spring source did not notify us in a timely manner, we have discontinued the use of this source,'' the notice from Niagara Bottling said.
