TAIPEI, Taiwan – The city health department in Taipei, Taiwan recalled US pork meat after pork balls made from the meat were found to contain ractopamine, according to Focus Taiwan.

Health officials recalled 119 kg. (262 lbs.) of pork, but 141 kg. (311 lbs.) of pork had been made into pork balls and sold to 17 breakfast stores, according to local health officials. The pork balls contained 0.4 parts per billion (ppb) of ractopamine, a livestock feed additive. Ractopamine is banned in pork imports to Taiwan but allowed in imported beef.

Officials investigating the matter said the meat came from a single supplier that ordered the meat from a Taipei importer, according to Focus Taiwan.

The investigation also found pork burger meat that contained chloramphenicol, an antibiotic that is banned in pork in Taiwan. Violations of Taiwan's Act Governing Food Sanitation can result in fines between TWD$60,000 ($2,046) and TWD$6 million ($204,700).
