What This Means for Your Facility
Pathological waste occupies a unique regulatory position in California's medical waste framework. Under the MWMA (HSC §117690), pathological waste includes recognizable human tissues, organs, and body parts removed during surgery, autopsy, or other medical procedures, excluding teeth, contiguous structures of combings and shavings of nails, and hair. The law mandates incineration as the sole approved treatment method for pathological waste. Autoclaving, chemical treatment, and other alternatives permitted for biohazardous waste are not acceptable for pathological waste.
The incineration requirement means that pathological waste must be transported to one of a limited number of permitted incineration facilities, which are subject to strict EPA and CARB emissions standards. This creates logistical and cost considerations that facilities must plan for. Pathological waste must be double-bagged in red bags, placed in rigid leak-proof containers, labeled with the biohazard symbol and the words "pathological waste," refrigerated if stored for more than 24 hours, and manifested for transport.
BayArea Compliance manages pathological waste disposal for surgical centers, hospitals, pathology labs, and veterinary facilities across the Bay Area. We provide compliant containers, coordinate pickups on a schedule that ensures waste never exceeds storage time limits, transport to permitted incineration facilities, and maintain complete manifest documentation. For facilities with infrequent pathological waste generation, we offer on-call pickup services so you are not paying for scheduled service you do not need.
