Dr. Su Wei-shuo, a psychiatrist who has long petitioned against the import of US meat products containing the leanness-enhancing feed additive ractopamine, has been in the spotlight recently.

Su is a vocal critic of the government’s decision to lift restrictions on US pork imports, which took effect on January 1. He has said that the feed additive is unsafe for human consumption and that the government has turned a blind eye to individual health. That’s despite the government’s position that its decision to allow in pork treated with ractopamine is based on international standards and scientific evidence.

Su said that ractopamine is 250 times more poisonous than MDMA, a synthetic drug commonly known as Ecstacy. What’s more, he said that simply by inhaling the chemical could be hazardous to the health, potentially leading to problems such as mental illness and autism in children.

While Dr. Su later revised his statement by saying that ractoapmine is only one fourth as poisonous as Ecstacy, he has been charged with spreading false information under the Act Governing Food Safety and Sanitation. If found guilty of the charges, he could be thrown into jail.
