The Product Board Animal Feed has a number of monitoring programmes through which it keeps a finger on the pulse. By studying the results it is able to detect undesirable developments promptly and see how they are to be managed. The monitoring programme for chemical contaminants focuses on aflatoxin, cadmium, pesticides and Salmonella.

In the Netherlands the National Inspection Service for Livestock and Meat (Rijksdienst voor de keuring van Vee en Vlees, RVV) and the General Inspection Service (Algemene Inspectie Dienst, AID), acting on behalf of the government, monitor whether the national and international regulation in the area of agricultural chemicals is being observed. But the meat production sector itself is also increasingly active in this area. To be able to guarantee food safety, limits have been set for harmful substances that may end up in meat, either intentionally or unintentionally.

In the Netherlands the National Inspection Service for Livestock and Meat draws up the National Plan on Hormones and Other Substances on behalf of the government. The plan describes how the monitoring of livestock and meat for residues is to be performed in the coming year. Each Member State of the EU is required to draw up such a monitoring plan. The plans must be approved by Brussels and the results from the monitoring of the past year must be reported to Brussels.

The government has tried in many ways, including regulations, to limit or even prevent the pollution of surface water. For example, environmental permits generally stipulate the volume of waste products that a company may release into the surface water in a given period.

In the Netherlands about 0.5 percent of all animals slaughtered are examined for traces of antibiotics, using the new Dutch kidney test. This test measures an effect, such as the inhibition of bacterial growth. The test can demonstrate that bacteria growth inhibitors are present in a sample, but can not identify the specific chemical responsible for the inhibition. The proportion of animals that test positive with this test has been stable for some years at about 0.2 percent.

A monitoring programme for Dutch recreational fishing has been in place for many years. This measures the pollution of eels with PCBs, organochlorine compounds and mercury.

Action limits’ have been set for substances for which no residue limits have been set in the law, to be able to decide whether the result of a residue analysis should be regarded as positive or negative. The action limits for natural hormones depend on the age and gender of the animal.
