Unfair trading practices which, in the absence of effective EU legislation, Parliament has begun trying to improve. The supermarkets have significant selling power and the power to put pressure on the producers. MEPs highlight the situation where suppliers are forced to sell at below the production costs or bear the costs of supermarket offers. 

Suppliers find themselves in a disadvantaged position because the big chains dictate the terms. Individual farmers should be able to live with dignity by the sale of these products and not only to get rid of them and sell them at a price below the production cost.
