Overview

• In a review of 20 deaths, the Cuerpo Médico Forense found no direct causal link but classified 12 as having a concausal nexus, four as fortuitous, and four as indeterminate due to gaps or timing issues.
• ANLIS–Malbrán confirmed Klebsiella pneumoniae MBL and Ralstonia mannitolilytica in ampoules and established phenotypic, molecular and genomic identity with patient isolates from the same cases.
• The Health Ministry’s surveillance now lists 50 deaths reported by jurisdictions, while the La Plata federal case file compiles 87 confirmed and nine suspected deaths as judicial reviews continue.
• Regulatory fallout widened as the Health Ministry removed ANMAT’s post‑market surveillance director and internal records show critical quality failures were documented at the Ramallo plant before the December 2024 production of lots 31202 and 31244.
• Córdoba officially reported six cases to national surveillance and Río Negro notified one under investigation, while federal investigators also probe missing precursor quantities and potential diversion linked to HLB Pharma/Laboratorios Ramallo.
