The ChemKAP website was developed in order to provide general information on contaminants and pesticides, information on the KAP-database and the description of various risk and exposure assessment tools.

Fruit and vegetables are healthy. Scientific research has shown that if people were to eat more fruit and vegetables there would be considerably fewer cases of cancer. However the most recent dietary survey conducted in the Netherlands (Voedselconsumptiepeiling, VCP-3) shows that the consumption of fruit and vegetables has declined considerably.

The ß-agonist clenbuterol and comparable substances such as cimaterol and salbutamol cause a shift from the production of fat to the production of muscle tissue in calves and other animals. The substances are not without danger for humans.

The registration of chemicals that are used has been the usual practice in the Environmental Conscious Cultivation (Milieubewuste voedingstuinbouw, MBT) for several years. The aim of the programme is to stimulate environmentally aware horticulture.

The analysis of meat for environmental contaminants focuses on substances such as polychlorobiphenyls (PCBs) and a number of organochlorine substances, such as lindane and dieldrin/aldrin. These substances are known to be able to accumulate in the food chain. As in previous years, there were no violations of the limits set in the Commodity Act or the Pesticide Act. A certain percentage of the fat samples had a positive test result, the percentages differing per species. It is especially hexachlorobenzene and to a lesser extent lindane that are found now and then.

In the Netherlands the Dutch government and agribusiness have set up the Multi-year Plan Crop Protection. One important objective for the year 2000 is to halve the use of pesticides in comparison to 1984-1986. Other goals are to make the agricultural sector in the year 2000 less dependent on chemicals and to reduce the emission of pesticides into the environment.

A lot of attention is given in the National Plan to traces of antibiotics. There is a risk, with long-term use of antibiotics, that the bacteria causing a disease may become resistant to the antibiotic. So the excessive preventative use of antibiotics has been condemned nationally and internationally. Every country in the EU is required to check 0.1 percent of slaughtered animals for the presence of bacterial growth inhibitors, such as antibiotics and sulphonamides.

In the Netherlands, the Inspectorate for Health Protection, Commodities and Veterinary Public Health (Inspectie W en V) monitors compliance with the Pesticide Act on behalf of the government. Every year the Inspectorate takes about 10,000 samples of fruit and vegetables. These are examined for possible traces of pesticides, looking for a wide range of pesticides. The results of the analyses are compared to the residue limits set in the Pesticide Act.
