Question about mixed minced meat?

Hi everyone,

I just picked up some mixed minced meat from the butcher at Edeka. After paying, I packed it in my cooler bag between ice packs, along with other groceries like cheese, etc.

I put the cooler bag in my bike bag and it took me about 10-20 minutes to get home. The ride home was sunny the whole way, and today it's still 35°C. When I got home and took the ground beef (which was packed in a bag) out of the cooler bag, it didn't feel that cold, even though there were a lot of ice packs in the cooler bag.

Should I be worried, or is the ground meat still safe to eat? I wanted to fry it today…
