Possible sources of contamination of bee products

1. Pollutants from the environment

Pollutants may fall into the honey and bee products by air, water and bees by themselves or nectar, pollen and propolis, derived from plants.

Microbial contamination does not present a risk to human health - has shown that it is not necessary microbiological control of honey.
Radioactive pollution, CFCs established in honey are low and safe health.
Heavy metals - need to control their presence in honey.

Pesticides (insecticides, fungicides, herbicides, etc.). The risk of the use of pesticides is related mainly to the toxicity of their bees. The likelihood of contamination of honey is small, but the bee pollen is kontraminira greater.
Antibiotics are used in some cases to combat diseases in plants and from there through meetings and pollen bees and honey bee products in the fall. Their presence is unacceptable.
Genetically modified plants - EU genetically modified organisms are prohibited and limit the quantities of natural foods are 1%.

Synthetic akaritsidi - they are the most serious source of contamination of bee products, as generally used to combat varroasis. In Propolis may accumulate akaritsidi, but especially dangerous accumulation in their wax, which is used for making wax bases.
Antibiotics - use them to fight American foulbrood is banned in the EU and honey are not allowed any residues.
Paints, impregnating, varnishes containing insecticides and fungicides.
Repelentni use of chemicals, carcinogenic materials for fumigation.
Storage of honey in inappropriate and vessels.
