Public analysis laboratories run by local authorities are an essential part of public health safety policy; these laboratories are an integral part of the risk prevention and health crisis management system. They operate in the fields of veterinary public health, plant health and in monitoring the quality of food, drinking water and the environment.
In the event of a serious threat or damage to public health, the representative of the State in the department will immediately call upon the laboratory of the departmental veterinary service or the hydrological laboratory or, failing this, those of another department in coordination with the representative of the State in the department concerned, as necessary, to carry out his or her duties.
