Porcine DNA in Candy
Parameters (qualitative): Identification of the animal species pork
Article Number: 2010313
Description: Increased interest in the detection of animal species in food has been observed, in particular in highly sensitive analytical methods, especially for the species pig. The real-time molecular biological method based on the amplification of DNA allows specific detection of DNA and DNA fragments of the respective species. The sensitivity depends on the PCR system used, the matrix and the degree of processing of the food. A relative quantification is possible by determining the Ct values, but the systems are calibrated for raw muscle meat. In this proficiency testing, gums are used as matrix for the qualitative detection of low amounts of porcine DNA.

Pyrrolizidine alkaloids in honey
Parameters (quantitative): Screening for at least 9 different pyrrolizidine alkaloids, e.g. monocrotaline, heliotrine, retrorsine
Article Number: 2011006
Description: Honey is one of the major sources for consuming toxic pyrrolizidine alkaloids (PA). PA are present in over 6000 plant species and function as protecting agents against predators. PA are liver-damaging and most likely carcinogen. Therefore, honey with high PA levels should not be sold.
