NEW YORK (AP) — Niagara Bottling has recalled 14 brands of bottled spring water produced at two Pennsylvania manufacturing plants after the operator of one of its contracted springs failed to reveal evidence of E. coli bacteria at the spring source.

The company said E. coli bacteria was found in the water supply on June 10, but that there has been no E. coli contamination detected in its finished products or in the spring water delivered to its bottling facility. It has not received any complaints of injury or illness.

E. coli can cause diarrhea, abdominal cramping, nausea and vomiting.

Niagara Bottling LLC is recalling spring water products made at two plants in Pennsylvania between 3 am Eastern on June 10 and 8 pm on June 18. The facilities are located in Hamburg and Allentown.

The water is labeled under brands including Acadia, Acme, Big Y, Best Yet, 7-11, Niagara, Nature’s Place, Pricerite, Superchill, Morning Fresh, Shaws, Shoprite, Western Beef Blue and Wegman’s.

Consumers should not drink the affected water without boiling it first to kill bacteria and other organisms. The company also suggests using other bottled water.

Niagara Bottling is no longer using the spring source because the operator did not notify the company of the incident in a timely manner.

Consumers may contact Niagara Bottling at 877-487-7873 or visit its website (niagarawater.com) for more information about the voluntary recall.
