Gloves and respirator, hand wash all of the dishes one at a time, put them on the counter. Feel the sink full of hot water add bleach to proper disinfectant levels plus a little bit for sanity. Soak the dishes in the bleach water for 30 minutes. Hand rinse, hand dry, put them away.

Fresh sink of sanitizer

Take the baskets and filters out of the dishwasher, hose them off outside. Put any parts small enough to fit in the sink into the sanitizer. Disassemble the steam vent in the front spray it down with something bleach-based, If any parts can be safely removed and don't have metal put them in the sanitizer too.

Use 409 or something bleach-based to spray out the inside of the tub and scrub it down with paper towels.

Put the baskets, filters and vents back in. Add a cup of vinegar and run a heavy duty cycle.

Have to make sure you don't let bleach sit in the tub for too long it'll destroy the seals and it can be rough on the circulation pump.

Not my first biohazard, probably not my last either.
