A PA meat establishment is recalling pork products after inspectors found the facility's water test results had been positive for coliform bacteria. These test results would classify the water as non-potable.
While the risk is probably low to non-existent (the fresh pork itself would have coliforms), the water used to make that product is deemed as non-potable. While the presence of coliforms in themselves are not a hazard, their presence could indicate that other pathogenic bacteria could be present. More importantly, their presence could indicate that a contamination pathway could exist linking the water supply to a contamination source - surface water, septic system, animal waste, etc.
Corrective action needs to be taken immediately upon these types of results. This is normally done by dosing or shocking the well with chlorine. or even better for protecting a business is continuous disinfection.
