Niagara Bottling LLC has issued a voluntary recall for 14 brands of its bottled water produced at two Pennsylvania plants because of concerns once of its spring sources is contaminated with E. coli.

The company says E. coli bacteria was found in the water supply on June 10. The recall covers all bottled water produced at the Pennsylvania plants from June 10-18 which were sold under brand names including Acme, Acadia, Big Y, Best Yet, 7-11, Niagara, Nature’s Place, Pricerite, Superchill, Morning Fresh, Shaws, Shoprite, Western Beef Blue and Wegman’s.

Niagara says an operator at one of the springs failed to report the E. coli bacteria. However, the company says it performs testing on both the incoming spring water and finished products and confirmed no issues or E. coli contamination detected.

“Even if it had been present in the incoming spring water, we utilize quality systems and disinfection technology that would ensure that our product is free from contamination,” the company said. “Despite this, once we were informed of the potential presence of E. coli at the spring source, we immediately shut down our operations, disinfected our bottling lines and initiated a voluntary recall in an abundance of caution and in the interests of consumer safety.”

The company has received no reports of illness related to consumption of these products.
