HARTLAND, WI (WTAQ) - The federal government says at least three more deaths may have been caused by contaminated alcohol wipes made by a southeast Wisconsin firm.

That brings to 11 the number of deaths reported to the Food and Drug Administration as the possible result of alcohol skin care products made by the Triad Group of Hartland.

The group’s H-and-P plant has been shut down for most of the year while federal authorities investigate.

U.S. marshals raided the plant and took products said to be contaminated with a bacterium that’s deadly when it gets into blood or a spinal canal.

The Milwaukee Journal Sentinel had earlier said the FDA identified problems at Triad for more than a decade, but it never acted against the firm.

Meanwhile, more questions were raised about the FDA’s actions, after the family of a Houston toddler said the agency never contacted them once the boy’s apparent death from Triad wipes was publicized almost a year ago. The family has sued the company in that death.
