E233 is a food additive approved by the European Union (EU) and used as an antibacterial and antifungal synthetic preservative in food products. It is also used in veterinary applications.
The common name for E233 is thiabendazole.
Fruits can be sprayed or dipped in thiabendazole to cover the fruit.
When used in the treatment of some medical conditions, almost one third of patients suffered symptoms of nausea, vomiting, vertigo, diarrhoea and even anorexia. E233 is banned in Australia.
