Article 5

Member States shall prescribe that medicated feedingstuffs may be placed on the market only in packages or containers sealed in such a way that, when the package is opened, the closure or seal is damaged and they cannot be re-used.

Where road tankers or similar containers are used to place medicated feedingstuffs on the market, these must be cleaned before any re-use in order to prevent any subsequent undesirable interaction or contamination.
