Ensuring compliance with Islamic dietary laws, particularly the prohibition of pork consumption, is crucial in halal food production. However, inadvertent contamination or mislabeling of products containing pork-derived ingredients presents a challenge to maintaining halal integrity. Molecular detection techniques offer a sensitive and specific means of detecting even trace amounts of pork contamination. These methods, including PCR, qPCR, ELISA, and DNA microarray analysis, target unique genetic markers or protein signatures exclusive to pigs. By providing reliable and rapid detection capabilities, molecular assays enhance the ability to verify the absence of pork-derived ingredients in halal food products, thereby upholding their authenticity and fostering consumer trust.
