E233PreservativeElevated concern
Thiabendazole
In plain words
The short version
A benzimidazole fungicide for citrus wax — banned in EU food (2014) but still common in US imports.
Why we flag it
It's allowed, but comes with clearer cautions — such as reactions in sensitive people, stricter limits, or contested safety. The Safety section below explains why.
Safety profile
EU ADI revoked; US tolerance 0.05 mg/kg body weight. Higher reproductive and developmental toxicity signal than the orthophenylphenol class drove the EU revocation. The medical anthelmintic dose is hundreds of times higher than dietary exposure.
