Quality violations at Tedor Pharma’s Cumberland, Rhode Island site netted the drugmaker a Form 483 from the FDA for inadequate testing, cleaning and calibration procedures.

During a Jan. 14-31 inspection, the FDA investigator found deficient cleaning and testing processes for multi-use production equipment. Specifically, the equipment wasn’t properly evaluated for bacteria on the  surface. The agency also cited the facility for equipment calibration procedures.

In addition, the firm failed to conduct studies to determine if construction materials for a distribution loop and holding tank had an effect on water quality over time.
