FDA's MAUDE database holds 463 reports that name the brand "BD Phoenix M50 Automated Microbiology System" (system test automated antimicrobial susceptibility short incubation), received between February 2021 and August 2026; the manufacturer given most often on reports is Becton Dickinson & Sparks. Spellings of one product vary from report to report.

143 reports arrived in the 12 months to August 2026, up 74% from 82 in the 12 months before. FDA releases MAUDE data monthly; reports can arrive months after an event, so the newest months grow in later releases. The event types recorded are malfunction (99.8%) and injury (0.2%); across all system, test, automated, antimicrobial susceptibility, short incubation reports (product code LON) death is recorded in 0.2% and malfunction in 98%.

The device problems coded most often are incorrect, inadequate or imprecise result or readings (69.5%), incorrect measurement (31.3%) and false positive result (0.6%). FDA states that "MDR data alone cannot be used to establish rates of events, evaluate a change in event rates over time or compare event rates between devices. The number of reports cannot be interpreted or used in isolation to reach conclusions about the existence, severity, or frequency of problems associated with devices." It adds that the reporting system "has limitations, including the potential submission of incomplete, inaccurate, untimely, unverified, or biased data."
