Commission Decision
of 15 April 2004
authorising methods for grading pig carcases in the United Kingdom
(notified under document number C(2004) 1340)
(Only the English text is authentic)
(2004/370/EC)

THE COMMISSION OF THE EUROPEAN COMMUNITIES,
Having regard to the Treaty establishing the European Community,
Having regard to Council Regulation (EEC) No 3220/84 of 13 November 1984 determining the Community scale for grading pig carcases, and in particular Article 5(2) thereof,
OJ L 301, 20.11.1984, p. 1. Regulation last amended by Regulation (EC) No 3513/93 (OJ L 320, 22.12.1993, p. 5).
Whereas:
(1) Article 2(3) of Regulation (EEC) No 3220/84 provides that the grading of pig carcases must be determined by estimating the content of lean meat in accordance with statistically proven assessment methods based on the physical measurement of one or more anatomical parts of the pig carcase; the authorisation of grading methods is subject to compliance with a maximum tolerance for statistical error in assessment; this tolerance was defined in Article 3 of Commission Regulation (EEC) No 2967/85 of 24 October 1985 laying down detailed rules for the application of the Community scale for grading pig carcases.
OJ L 285, 25.10.1985, p. 39. Regulation amended by Regulation (EC) No 3127/94 (OJ L 330, 21.12.1994, p. 43).
(2) By Decision 88/234/EEC, the Commission authorised the use of five methods for grading pig carcases in Great Britain and three methods in Northern Ireland.
OJ L 105, 26.4.1988, p. 15. Decision last amended by Decision 2003/750/EC (OJ L 271, 22.10.2003, p. 24).
(3) The United Kingdom has requested the Commission to authorise the use of new formulae for the apparata used for grading pig carcases in Great Britain and has submitted the details required in Article 3 of Regulation (EEC) No 2967/85. An examination of this request has revealed that the conditions for using the new formulae are fulfilled.
(4) Article 2 of Regulation (EEC) No 3220/84 lays down that Member States may be authorised to provide for a presentation of pig carcases different from the standard presentation defined in the same Article where commercial practice or technical requirements warrant such a derogation.
(5) In the United Kingdom commercial practice does not require that the tongue is removed from the pig carcase; this should be taken into account in adjusting the weight for standard presentation.
(6) In accordance with Article 2(3) of Regulation (EEC) No 2967/85 and by way of derogation from Article 2(1) and (2) thereof, the weight of the cold carcase may be calculated by reference to pre-determined scales of absolute weight reductions if the reductions for individual weight classes correspond, as far as possible, to the reductions calculated in percentage terms; the United Kingdom has notified the determination of such a scale to the Commission.
(7) No modification of the apparata or grading methods may be authorised except by means of a new Commission Decision adopted in the light of experience gained; for this reason, the present authorisation may be revoked.
(8) For the sake of clarity, a new Decision should be adopted and Decision 88/234/EEC should therefore be repealed.
(9) The measures provided for in this Decision are in accordance with the opinion of the Management Committee for Pigmeat,
HAS ADOPTED THIS DECISION:

Article 1 The use of the following methods is hereby authorised for grading pig carcases pursuant to Regulation (EEC) No 3220/84 in the United Kingdom, excluding Northern Ireland:
the apparatus termed ‘Intrascope (Optical Probe)’ and assessment methods related thereto, details of which are given in Part 1 of Annex I,
the apparatus termed ‘Fat-O-Meater (FOM)’ and assessment methods related thereto, details of which are given in Part 2 of Annex 1,
the apparatus termed ‘Hennessy Grading Probe (HGP 4)’ and assessment methods related thereto, details of which are given in Part 3 of Annex I,
the apparatus termed ‘CSB Ultra-Meater’ and the assessment method related thereto, details of which are given in Part 4 of Annex I,
the apparatus termed ‘Fully automatic ultrasonic carcass grading’ (Autofom) and assessment methods related thereto, details of which are given in Part 5 of Annex I.
As regards the apparatus ‘CSB Ultra-Meater’ it is laid down that after the end of the measurement procedure it must be possible to verify on the carcase that the apparatus measured the values of measurement x1 and x2 on the site provided for in Annex I, Part 4, point 3. The corresponding marking of the measurement site must be made at the same time as the measurement procedure.
Article 2 The use of the following methods is hereby authorised for grading pig carcases pursuant to Regulation (EEC) No 3220/84 in Northern Ireland:
the apparatus termed ‘ Intrascope (Optical Probe) ’ and assessment methods related thereto, details of which are given in Part 1 of Annex II,
the apparatus termed ‘ Mark II Ulster Probe ’ and assessment methods related thereto, details of which are given in Part 2 of Annex II,
the apparatus termed ‘ Hennessy Grading Probe (HGP 4) ’ and assessment methods related thereto, details of which are given in Part 3 of Annex II,
the apparatus termed ‘ Fully automatic ultrasonic carcass grading (Autofom) ’ and assessment methods related thereto, details of which are in Part 4 of Annex II.
Substituted by Commission Decision of 3 February 2006 amending Decision 2004/370/EC authorising methods for grading pig carcases in the United Kingdom (notified under document number C(2006) 213) (Only the English text is authentic) (2006/99/EC).
Article 3 Notwithstanding the standard presentation referred to in Article 2 of Regulation (EEC) No 3220/84, pig carcases may be presented in the United Kingdom of Great Britain and Northern Ireland, with the tongue attached before being weighted and graded. In order to establish quotations for pig carcases on a comparable basis, the recorded hot weight shall be reduced by 0,3 kg.
Article 4 Notwithstanding the standard presentation referred to in Article 2(1) of Regulation (EEC) No 3220/84, the flare fat, the kidneys and the diaphragm need not be removed from pig carcases before being weighed and graded. In order to establish quotations for pig carcases on a comparable basis, the recorded hot weight shall be reduced:
for pig carcases up to 56 kg, by 0,7 kg
for pig carcases from 56,5 to 74,5 kg, by 1,1 kg
for pig carcases of 75 kg and over, by 1,6 kg.

Deleted by Commission Decision of 22 May 2006 amending Decision 2004/370/EC authorising methods for grading pig carcasses in the United Kingdom (notified under document number C(2006) 1988) (Only the English text is authentic) (2006/374/EC).
Article 6 Modifications of the apparata or of the assessment methods shall not be authorised.
