If it is endangered, contaminated, naturally toxic or was procured from dubious sources, there's a chance that the food is illegal. Beef from mad cow disease-infected countries for instance. We were able to receive some contraband steeped in sukang Iloko and ginger. Mayubyub, which are Samaral (
Siganidus) fingerlings, have been banned on Ilocano tables. My hypothesis is that these are stock of the collateral damage during dynamite fishing.
Is there any illegal food in your place?
