The immune system, just as any body system, is subject to destruction and d
ysfunction as a result of infection,toxins, stress and malnutrition. Second
ary immune deficiencies may occur as the result of a wide variety of toxic
substances abusing the physical body. One of the most important these are s
ubstances having immuno-suppressive or immuno-toxic properties such as drug
s, heavy metals, fertilizers, chemical insecticides and other xenobiotics p
olluting food. Honey and pollen that are contaminated directly or indirectl
y via the food chain by many environmental toxins such as DDT, lead, cadmiu
m, mercury or chemo-therapeutics present a risk factor for the immune syste
m of the human consumers of these honey bee products. The article documents
the suppressive action and/or allergic possibilities of honey contaminated
with sulfa drugs, antibiotics chloro-organic pesticides, nitrites and heav
y metals.
