An MD80 passenger reported becoming ill following an MD80 flight which had a preflight lavatory service with passengers on board and 'Blue' water somehow got into the airconditioning system.

Narrative

I was a passenger. I was seated in the rear of the aircraft. The flight was late in arriving and the crew did their best to turn the aircraft around to return to the next destination. After all the passengers were loaded; the ground crew performed maintenance on the toilet system of the plane. As they pumped the holding tank; an acrid smell came through the passenger air vents above the seats. It smelled like holding tank effluent as it had the perfume smell that is used in the 'blue' water. It was so bad that I turned off my air vent. That night after I got home; I experienced severe nausea and made several trips to the bathroom. As of this moment I am still experiencing bouts of dysentery. I believe that some of the holding tank effluent sprayed on the aircraft near the intake for the passenger air and spread some sort of contagion like Norwalk virus throughout the cabin air. There have been reports of flu or TB being spread through aircraft on the ground when cabin air is recirculated. At best such a procedure should not be done while the aircraft is loaded with passengers or greater precaution taken to insure that holding tank effluent is not allowed to escape while performing the procedure.
