I spotted the following note on the box of oranges I brought home from Costco:
Treated to maintain freshness in transport with one or more of the following Thiabendazole, Imazalil and coated with food grade natural resins and/or vegetable wax.
At Costco, the warning isn’t too helpful unless you know what those unpronounceable chemicals do or you have access to Wikipedia. If the warning just indicated that the two chemicals were fungicides, that would have made the warning 100% more informative.
