The only difference between organic and conventional food is the way in which the food has been produced and processed. For instance, the use of fertilisers and pesticides is restricted in organic production.
The difference between organic and conventional or traditional foods lies in the production process. All foods sold as 'organic' must be produced according to laws on organic production. Although organically produced foods cannot be defined as pesticide free, the direct use of other than "traditional" agricultural chemicals is prohibited.
