Weevil Woman

[Olive]

Pantry moths can get into very tight places - they lay eggs inside the lids of screw top jars, so it is possible that her olive jar was infested. The eggs can arrive in almost any dried goods including spices. I had an infestation about ten years ago and got on top of it by throwing out the entire contents of the pantry, washing all of the containers and lids in the dishwasher, using pantry moth traps, and keeping dried fruit and nuts in the freezer. I haven't had another infestation since.

I think that person seeking compensation from the supermarket is pushing it a bit - pantry moths are a fact of life in warm climates and the distributors of dried goods do their best but can only do so much.
