Article 5
1. The temperature of quick-frozen foodstuffs must be stable and maintained, at all points in the product, at -18 °C or lower, with possibly brief upward fluctuations of no more than 3 °C during transport. 2. However, tolerances in the temperature of the product in accordance with good storage and distribution practice shall be permitted during local distribution and in retail display cabinets subject to the following conditions: (a) these tolerances shall not exceed 3 °C; (b) they may, however reach 6 °C in retail display cabinets, if and to the extent that the Member States so decide. In that case, the Member States shall select the temperature in the light of stock or product rotation in the retail trade. They shall inform the Commission of the measures taken and of the grounds for those measures. The Commission shall review the tolerance provided for in the previous subparagraph in the light of technical developments and shall make proposals to the Council if appropriate before 1 January 1993. 3. For a period of eight years from the notification of this Directive, the Member States may, for local distribution, authorize tolerances of up to 6 °C.
