OpenBiome update on recent FDA safety alert

Press Release


OpenBiome screens for antibiotic-resistant bacteria, including the bacteria involved in a recent safety alert from FDA. OpenBiome did not provide the FMT material linked to this event and our service remains uninterrupted.


On Thursday, June 13, 2019, the FDA issued a safety alert regarding two fecal microbiota transplant (FMT) recipients who acquired Extended Spectrum Beta-Lactamase (ESBL)-producing Escherichia coli infections following FMT, resulting in one death. The material used in these cases was not from OpenBiome. We are continuing to service clinical providers and clinical researchers as usual.

OpenBiome screens donors for several antibiotic-resistant bacteria, including ESBL-producing organisms, carbapenem-resistant enterobacteriaceae (CRE), methicillin-resistant Staphylococcus aureus (MRSA), and Vancomycin-resistant enterococci (VRE), as well as evaluating for risk factors associated with acquisition of these microbes. In response to this event, the FDA has introduced new screening requirements for FMT material. We already meet these requirements as part of our routine donor assessments.

This event underscores the importance of robust safety and quality infrastructure for FMT, and of informing patients of the risks associated with FMT and alternatives. Although OpenBiome has provided more than 45,000 treatments with no reported infections or deaths definitively resulting from FMT material, vigilant management of safety is our highest priority. We are here to support patients and the community of healthcare providers and clinical researchers who serve them. Please do not hesitate to use us as a resource.

FOR PATIENTS: If you have questions or concerns about your FMT, please reach out to your doctor. You may also find additional resources at or you may reach us at

FOR PROVIDERS: You may reach us at and you may review our Quality and Safety Program, including our donor screening criteria, at
