This document specifies a procedure to determine the HADH activity in poultry meat samples by spectrophotometry. The results can provide an indication whether poultry breast meat has been previously frozen based on the ratio of relative HADH activity, and can be used to verify the labelling of poultry breast meat sold as chilled poultry. A result above a value of 0,5 for the ratio of HADH activity from a sample before and after laboratory freezing, indicates that the sample has been previously frozen. This document is applicable to chicken and turkey breast meat but can be used for other cuts and/or species with appropriate limit values. Additional validation can be required. The document is not applicable to minced meat or to poultry preparations. The compliance assessment process is not part of the document.
