1. Endogenous production of ethylene & ethylene oxide in your body. The 

source is gastrointestinal bacteria. The risk? Probably comparable to 

natural background ionizing radiation. Ethylene oxide is very genotoxic 

(showed to be mutagenic already around 1957).



2. Natural pesticides (in cabbage type of vegetables for instance). Search 

for publications by Bruce Ames et al. If I recall correctly Bruce Ames said 

about 14 years ago that one cabbage type had 54 natural pesticides - 27 of 

which turned out to be mutagenic in Salmonella (the so called "Ames test"). 

I eat a variety of foods and do not worry about this BTW.



My personal initiative only,
