I left a vacuumed sausage, still in wrapper in my car for about a month with temps of 100F, but the wrapper looks normal. Is it still good?

The wrapped sausage was also kept in a thick cardboard box, gift box that doesn't seem to retain much heat on the inside.
My question is that if the plastic appears to not have melted in any fashion, would any carcinogens from the plastic have sept into the sausage? It essentially looks identical to when it was purchased.

I only ask, because this is expensive sausage I forgot about.
