PORTLAND — Shaw’s and Hannaford stores are recalling house brands of bottled water after E. coli bacteria was found in the water’s supply.

The Portland Press Herald reports Shaw’s brand of bottled water and Hannaford’s Nature’s Place water are both bottled by Niagara Bottling Co. in Pennsylvania. The bacteria was detected at one of the springs from which the company obtains water. The company says no E. coli was detected in the spring water delivered to its plants or the finished products.

The bacteria causes cramping, nausea, diarrhea and vomiting. The stores are advising customers to not drink the water and to return it to the store for a full refund. The products have “best by” dates of Dec. 8, 2016 through Dec. 16, 2016.
