From the newest article (Multi-Product API Facilities and the Contamination Gap FDA Finds): FDA's question at a multi-product API site is not whether a cleaning SOP exists but whether the facility can prove, with current product-specific evidence for every equipment-product pair, that its controls are calibrated to the product range it runs today.

    Multi-Product API Facilities and the Contamination Gap FDA Finds

    FDA's March 2026 warning letter to Henan Lvyuan Pharmaceutical points to a contamination control failure pattern that is structurally embedded in how most multi-product API facilities operate. The gap is not usually in the SOP. It is in the evidence.
