Presence of flies in sample storage room, un-calibrated instruments in laboratory and non-adherence to sample analysis procedure were among the lapses found in Ranbaxy's Toansa plant that led to US health regulator FDA banning imports of drugs made at the facility.
According to the report released by the US Food and Drug Administration (FDA) inspection teams, as many as eight lapses were identified, including "Too Numerous To Count (TNTC) flies" in sample storage room, inadequate control over samples and non-adherence of procedures in sample analysis, during their visit to the Toansa, Punjab facility.
Other lapses included usage of un-calibrated and unqualified instruments in laboratory, said the report, which was released two days ago.
"Our inspection of QC Analytical and Microbiological laboratories found the facility to be in significant disrepair. Laboratories windows within the instrumentation (HPCL) rooms were found to be un-closeable.
"Too Numerous To Count (TNTC) flies were observed throughout the sample preparation room, and laboratory re-agent, equipment and documentation storage cabinets were found to be broken and un-closeable," FDA inspection report said.
Earlier this week, FDA banned the import of Ranbaxy products from its Toansa plant, halting the shipment of all the company's drugs to the US from India.
This is the company's fourth plant to face regulatory action from the American health regulator after Mohali, Paonta Sahib and Dewas plants. Expressing disappointment over the FDA ban, Ranbaxy had said it will cooperate with FDA and "comply with Consent Decree in both letter and spirit".
