Two former ANMAT officials were prosecuted for adulterated fentanyl

Two former officials of Argentina's National Administration of Medicines, Foods, and Medical Technology (ANMAT), Nélida Agustina Bisio and Gabriela Mantecón Fumadó, were formally charged by federal judges in La Plata for their alleged role in the contamination of fentanyl that caused at least 90 deaths. The judge, Ernesto Kreplak, ruled that they were necessary participants in the crime of medicinal substance adulteration. The charges include severe injuries to two people, serious injuries to 41 others, and minor injuries to one victim. Kreplak ordered a $500 million asset freeze for each defendant and maintained restrictions on their travel abroad. Both women had been detained earlier but were released after being deemed not a flight risk. They will continue the legal process without preventive detention.

The Federal Court of La Plata has charged two former officials from Argentina’s National Administration of Drugs, Foods and Medical Technology (ANMAT) with complicity in the adulteration of fentanyl that led to at least 90 deaths. Judge Ernesto Kreplak ruled that Nélida Agustina Bisio and Gabriela Mantecón Fumadó were necessary participants in the crime of medicinal substance adulteration. The court also found that at least two individuals suffered severe injuries, 41 sustained serious harm, and one incurred minor injuries. Kreplak ordered asset freezes worth $500 million each, general asset restrictions, and continued travel bans against both women. Both had been detained earlier this month but were released pending further investigation, as the judge rejected preventive detention during the ongoing legal process. The charges stem from a series of administrative failures linked to the contaminated fentanyl produced by HLB Pharma and Laboratorios Ramallo. According to the judge's nearly 300-page ruling, Bisio, who served as head of ANMAT during the relevant period, failed to apply technical standards and administrative procedures required when addressing irregularities detected in these pharmaceutical companies. One key issue was a January 14, 2025 meeting between ANMAT authorities and representatives of both firms, which lacked official documentation. Another concern was the lack of a formal warning letter sent to HLB Pharma, which would have prohibited the commercialization of certain medications. Kreplak emphasized that these decisions represented inadequate sanitary oversight, which fell under Bisio’s responsibility as the agency’s top authority. He also examined her ties to the Ministry of Health of the Nation, suggesting a potential influence over regulatory actions. Regarding Mantecón Fumadó, who headed the National Institute of Medicines (INAME), the judge questioned the handling of administrative procedures and the timeframes used to address the laboratories. In her recent testimony, she claimed that the production area responsible for fentanyl had not been inspected in November 2024 because there were no quality reports indicating problems in that section. She argued that inspections focused on other areas based on previously identified violations, which she described as critical but not affecting the fentanyl production zone. Mantecón Fumadó also stated that the laboratory produced several fentanyl batches in December 2024, including lots numbered 31202 and 31244. She claimed she became aware of related reports only on May 5, 2025, after which she prioritized the case. However, the court noted discrepancies in her timeline and the timing of internal communications. The investigation also highlighted the relationship between ANMAT and the Ministry of Health, with Bisio reportedly transmitting information about proceedings against HLB Pharma and Ramallo while receiving directives on how to proceed. The judge incorporated statements from the ex-officials regarding Health Minister Mario Lugones and an instruction to handle irregularities at Ramallo with caution. The case continues to unfold, with legal proceedings set to advance as the court examines additional evidence and testimonies. The implications extend beyond individual accountability, raising questions about systemic failures in drug regulation and political influence within public health institutions. As the legal process moves forward, the outcomes could shape future policies and oversight mechanisms in Argentina’s healthcare system.
