This blog focuses on exploring the connection between mold toxins (and other toxicity) and diseases related to Myalgic Encephalomyelitis (M.E.). The main authors are Erik Johnson and Lisa Petrison, with additional essays by guest authors.


Erik Johnson has focused on the issue of the effects of toxic mold and other biotoxins on human health since the early 1980’s, when he first became ill with M.E. (labeled “Chronic Fatigue Syndrome” by the CDC) as part of the Lake Tahoe Epidemic. He has maintained control over his symptoms — including working full-time and exercising vigorously on a regular basis — through what he calls “Extreme Mold Avoidance” since 1998.

A book about Erik’s experiences is available here:



Lisa Petrison was a tenure-track professor in business at Loyola University Chicago before becoming disabled with CFS in 2001. Since 2008, she has focused her attention on issues related to toxic mold and other environmental toxicity. She is currently mostly recovered from the illness. Her Ph.D. is in marketing and social psychology from the Kellogg School of Management at Northwestern University.
