The fact in itself cant be disputed, so the question is on the extend of the problem!

Nairobians eating poison - Tests on samples of foods in markets and supermarkets have shown dangerous levels of toxins like calcium carbide, hydrogen peroxide, polychlorinated biphenyl-laden transformer oil, formalin and lead.

How does Hydrogen peroxide gets its way in our miok?

from my old chem... I remember Hydrogen Peroxide is even present in rain water (lightening creates it from the water and oxygen in the air). the only risk I see with huge doses of Hydrogen peroxide is that when it disassociates into water and oxygen - the oxygen is a single atom of oxygen (nascent oxygen as I remember it being called) not the Oxygen molecule we use for respiration and the effects of nascent are (were at the time I was reading this stuff) not exactly know to be positive to the human body - aging for example was then considered to be related to nascent oxygen consumption but don't fear... nascent oxygen is still available in air. I hope some chem people will correct my 20 year old chemistry with newer facts.
