In each département, at least one section carries out the tasks defined in chapter II of title I of this book in the farms, businesses and establishments defined in article L. 717-1 of the rural and maritime fishing code, unless an exception is justified by the low volume of agricultural activity and provided for by order of the ministers responsible for agriculture and labour. The Regional Director of Companies, Competition, Consumption, Labour and Employment may, if necessary, extend the scope of the agricultural sections as it results from the application of article L. 717-1 of the Rural and Maritime Fishing Code.
