The National Agency for Food, Drug Administration and Control (NAFDAC) says it is going after restaurants using paracetamol tablets in food preparation.
The agency said it had received a series of complaints that some restaurants in Maiduguri, Borno State, are using paracetamol to cook cow tail and legs.
Mr Nasiru Mato, the state coordinator of the NAFDAC, told newsmen in Maiduguri that the state office was alerted of possible use of the drug in food preparation, which led to a consultative meeting between NAFDAC and restaurant owners.
He said samples of such food had to be evaluated in the laboratory before drawing any conclusions.
The NAFDAC coordinator warned that any eatery found culpable would be sanctioned.
