    Abstract

    A fast procedure for species identification in heated meat is described. Deoxyribonucleic acid (DNA) was isolated from meat samples by an alkaline extraction method and hybridized to a conjugate of a specific oligonucleotide and alkaline phosphatase. The oligonucleotide probes are based on satellite DNA, tandem-repeated sequences, which are highly specific for species. Probes are developed for the identification of meat from cattle, sheep/goat, horse, deer, pig, chicken and turkey. Differentiation between closely related species like chicken and turkey is possible. Admixtures of 1-5% of meat of one species in another could be detected. The complete assay of up to 50 samples takes 4 h. Heated meat samples could be analysed.
