As a general rule, the European Community has exclusive competence for agenda items dealing with harmonisation of standards on certain agricultural products, foodstuffs, food additives, contaminants, veterinary drug, pesticides, fish and fishery products, including labelling, methods of analysis and sampling, as well as codes and guidelines of hygiene practice, insofar as the Community legislation has harmonised either completely or to a large extent the relevant fields in these areas, as well as issues of international trade to the extent that they are related to the objectives of the Codex Alimentarius Commission, notably to protecting the health of the consumers and ensuring fair practices in the food trade.
Na splošno ima Evropska skupnost izključno pristojnost za točke dnevnega reda, ki se nanašajo na harmonizacijo standardov glede nekaterih kmetijskih proizvodov, živil, živilskih dodatkov, onesnaževal, veterinarskih zdravil, pesticidov, rib in ribjih proizvodov, vključno z označevanjem, analiznimi metodami in metodami vzorčenja, kakor tudi glede kodeksov in smernic dobre higienske prakse, v kolikor je bila zakonodaja Skupnosti na teh področjih v celoti ali v veliki meri usklajena, kakor tudi glede vprašanj mednarodne trgovine, če so povezani s cilji Komisije Codex Alimentarius, zlasti na področju varovanja zdravja potrošnikov in zagotavljanja poštenega ravnanja v trgovini z živili.
