Many Africans do eat poisons in some food items on a daily basis as a result of wrong habit of cooking, processing and preserving foods.
Take for instance. Moin-moin (a local beans delicacy) which is mostly being prepared with cellophane wrap.The cellophane contains a large dosage of dioxins that are naturally impotent in leaves.
Dioxins are highly toxic and can cause reproductive and developmental problems, damage the immune system, interfere with hormones and also cause cancer.
So, my people, stop eating such food.
