A recent investigation by Food Unwrapped revealed that most doner kebabs in the UK contain meat other than lamb. Forensic scientist Paul Hancock tested nine doner kebabs from different establishments and found that only one contained 100 percent lamb DNA. The rest contained DNA from other animals such as beef and chicken. No traces of horse, donkey, or goat were found. Hancock suggested that a larger sample size would likely result in a 60 percent failure rate. The revelation has sparked mixed reactions among consumers, with some expressing concern about the quality and accuracy of the meat used in doner kebabs.
