Halal is one of the important aspects in Islam. Producing halal food is not an easy task as compared to making business transaction. This article will explain the process of traceability and authenticity of halal food supply such as chicken, beef and lamb. Before any of the products can be marketed, several procedures need to be conducted to ensure the authenticity of halal.  This is done by assuring there is no foreign substance such as elements of pigs that could contaminate the product. This paper will determine the methodology that focuses on past scientific research such as label test, spectroscopy test, and microbiology filtering test. The first test is to ensure the paperwork or statement produced by the suppliers is the same as ordered. Next, the product sample provided is taken for inspection to the lab to ensure the authenticity of the product. These tests include the label test, PCP-RFLP, real time PCR, Specific species PCR, and PCR sequencing. This test is to ensure the authenticity, safety and cleanliness of product stays in good condition.  The autenthicity of the halal product is guaranteed and safe to be consumed by Muslim consumers.

Abstrak
Halal adalah salah satu aspek yang sangat penting dalam Islam. Mengeluarkan bahan makanan yang halal bukanlah satu tugasan yang mudah dan ringan seperti yang dilakukan hanya untuk transaksi perniagaan. Artikel ini ingin menjelaskan proses kebolehkesanan dan kesahihan bekalan daging halal seperti ayam, lembu dan kambing. Sebelum pemasaran sesuatu produk itu dapat dilakukan, kesahihan halal produk tersebut harus dianalisakan di dalam beberapa tahap ujian. Dari segi metodologi, artikel ini memfokuskan kepada kajian-kajian saintifik lepas yang berkaitan dengan ujian label, ujian spectroscopi, dan ujian saringan mikrobiologi. Ujian pertama adalah dengan memeriksa kertas kerja atau penyata yang dikeluarkan oleh pihak pembekal adalah sama seperti yang dipesan. Kemudian, sampel produk yang dibekalkan akan diambil dan dihantarkan kepada makmal untuk menguji kesahihan produk. Ujian-ujian yang terlibat di dalam makmal tersebut termasuklah ujian label, PCR–RFLP, Real time PCR, Species-specific PCR, RAPD, PCR sequencing. Ujian yang dilakukan adalah bertujuan untuk memastikan kesahihan, keselamatan dan kebersihan produk sentiasa dalam keadaan yang baik. Kajian ini mendapati selepas melakukan proses tersebut, kesahihan berkenaan produk halal daging adalah lebih terjamin.
