Global food standards agency Codex Alimentarius is drawing up rules on the level of tin contamination allowed in canned beverages.

The rules have been drafted by the Codex committee on food additives and contaminants with the aim of formally adopting them by 2008.

Furthermore, the committee has announced that it wants to develop a code of practice for preventing Ochratoxin A contamination in wine. The code would only apply to winemaking regions where Ochratoxin A "has been found at significant levels in wine".

Data on the contamination will be collected by the committee, which might later propose the maximum level of Ochratoxin A in wine.
