This isn’t necessarily evidence of harmful contamination, which is another reason packaging appearance needs to be interpreted in context.
Changes in Temperature
Temperature can also affect the pressure and volume of gases inside packaging.
A package that looks somewhat different after being exposed to heat or changing environmental conditions isn’t automatically spoiled.
Still, if a perishable food has been exposed to unsafe temperatures, time and temperature history matter more than whether the package looks swollen.
Intentional Packaging
And sometimes the simplest explanation is the correct one.
The manufacturer may have intentionally filled the package with a protective atmosphere.
