Four food outlets have had their licences revoked with effect from Friday, for passing beef off as mutton last year. They were each fined $3,000 on April 24 under the Sale of Food Act.

The outlets are: Deen Biasa Restaurant, M. Mohamed Ismail Mee Goreng Specialist from Shenton Way, N.M Abdul Rahim from Shenton Way and A. Rashid Khan Mutton Soup Specialist from Shenton Way.

They were taken to court by the National Environment Agency (NEA).

In a media statement on Friday, the NEA said it investigated 15 restaurants and hawker stalls suspected to be serving beef in mutton dishes, following feedback received in October last year from members of the public. DNA tests found beef in samples taken from dishes from the four outlets and two others. The remaining two outlets will have their cases heard at the end of April.
