Cows’ milk casein shall be held to be present, if the appa- rent cows milk casein content of the sample to be analyzed is equal to or higher than the content of the reference sample described in the Annex. Article 2 Routine methods for the detection of cows’ milk casein in cheeses from ewes’ milk may be used under the following conditions : — the detection limit must be 0,5 % or lower, — false-positive results must not occur. If this cannot be excluded, any sample giving a positive result has to be analyzed using the reference method, () OJ No L 53, 1. 3. 1986, p. 23. () OJ No L 362, 27. 12. 1990, p. 3.
