Blown Packaging

[Chipchopper]

I bought a plastic tub of frozen sweet corn soup, a few days ago and when I took it from the freezer, I noticed that the lid and the base were bulging out.
I put it in the microwave for the recommended time and waited for the ping but decided to play safe and not eat it.
So, do you think I made the right decision ?

When water is frozen it expands which explains the bulging - I would expect the soup to be OK if it smelled sweet.

Yes i find food is a case of mind over matter if you ate it thinking you'd get ill then i think you would feel a bit ill. We do what we're comfortable with i can be very fussy when it comes to food dates, smells, look etc.. I always worry i'll get an upset tummy

[spathiphyllum]

but as geevo says it's very, very explainable why it expanded as things expand when frozen

[TonyV]

yes but microwaved would probably kill any bugs

Thanks for your good answers.
The tub seemed normal when I bought it and it was kept frozen.
However, I did have a slight doubt about the smell.
