Slightly different experience, but my parents were like this always when growing up, it never was an issue but it was just a constant thing that I inherited.

Nowadays though I have the extreme where if my food is in plastic I don't feel the food is contaminated (until recently, but for different reasons), but like the plastic is forever smelling of the food and filthy.

My gf uses plastic lunchboxes and even reuses plastic bottles and I swear I can smell the things around the appartment. It's gross.
