The Cambridge Public Health Department is holding a public hearing on a proposed addendum to current biosafety regulations. The new policies will “extend current Public Health oversight beyond rDNA work to include biological work using naturally occurring (“wild type”) and potential pathogenic organisms that would require BSL-3 containment or have been designated as Select Agents by federal authorities.” In addition to summarizing the new policies, the forum will include the timeline for implementation, and an opportunity for public comment. For more information, call 617-665-3838, or go the Health Department’s website to view the new regulations.
