A real case of massage releasing toxins--Holm 2009: Acute effects after occupational endotoxin exposure at a spa
In conclusion, ODTS [organic dust toxic syndrome] was diagnosed for two staff members performing seaweed massages at a spa center at which aerosolized endotoxin was measured. Endotoxin was found in fresh seaweed, and the concentration increased markedly with an increase in the length of storage of the seaweed. In minimizing endotoxin exposure, it is important to use either fresh seaweed or seaweed kept well cooled for no more than 2–3 weeks in a refrigerator.
