A Hartland, WI medical products manufacturer ceased production Monday after the U.S. Marshals Service arrived to seize materials. H&P Industries, which makes alcohol wipes and other products distributed by Triad Group, has been under investigation by the Food and Drug Administration for bacterial contamination issues. Triad Group has been sued by a Texas couple who blame the firm for the death of their 2-year-old son. In the lawsuit, filed in federal court in Houston, Shanoop and Sandra Kothari say an alcohol wipe from the company was the likely source of bacterial meningitis that killed their son, Harry, in November. Last week, the FDA asked H&P Industries to voluntarily stop production of its drug products.
