Taiwan tainted-oil controversy
Wei Chuan was drawn into Taiwan’s 2014 food-safety crisis after products were linked to ingredients or oils supplied through the wider adulterated-oil network. The company conducted recalls and faced intense public, regulatory, and legal scrutiny. The controversy raised questions about supplier due diligence, testing, traceability, and the responsibilities of major food manufacturers.
