EU agriculture ministers are set to hold talks on the crisis in the dairy industry.
An extraordinary meeting of the EU farm council on 5 October will discuss French proposals for intervention and aid to the dairy producers amid the collapse of prices.
The meeting follows weeks of protests which have seen farmers withhold supplies and dump millions of litres of milk on fields and streets.
The protests brought together farmers from all sectors to campaign against deregulation and a drop in the price of cereals.
In Paris, black banners were put up on the facade of the Trocadero opposite the Eiffel Tower. And in Strasbourg at least 1000 tractors drove through the city centre where farmers threw produce on to the streets.
Major protests also took place in Bordeaux, Auch, Toulouse and Arles. Organisers are planning further action for Friday, 16 October, unless EU ministers come up with a satisfactory rescue package.
