The Food & Environmental Hygiene Department has instructed a slaughterhouse operator to recall 40 pigs which came from a batch imported from the Mainland that was found to contain veterinary drug residues.
It told the operator, Ng Fung Hong, to trace the pigs' distribution and instructed 27 retail outlets to stop selling the pork.
The department’s health inspectors have visited those retail outlets to mark and seal the affected pork.
Some of the 319 pigs supplied from two Mainland farms tested positive for beta-agonists.
The department said people who have consumed meat containing an excessive amount of beta-agonist residues may experience symptoms including rapid heart rate, dizziness, headaches, tremors and nervousness.
It urged the public to stop consuming the pork and pig offal bought from the affected retail outlets yesterday. Medical advice should be sought if they feel sick after consumption.
It will conduct a comprehensive investigation into the case and has informed Mainland authorities.
It will exercise stringent control to ensure all pork and offal sold at retail outlets is fit for human consumption.
