Ate raw beef patty that I microwaved for 2 mins first, Is it safe?
You can cook meat products in a microwave, and be safe, but you need to make sure they're fully cooked.

Microwave ovens vary a lot in both their power output and how evenly they cook, so 2 minutes may not really be enough to be certain of cooking thoroughly. Next time I suggest you cut it in half when you think it's done, and check that the middle is both brown and very hot to touch. A thermometer would be the gold standard, but you're  not running a restaurant, you're feeding yourself with limited equipment. If in doubt, cook a little longer, and you'll know for the future. Repeat the test if you cook extra another time.
