Ate raw beef patty that I microwaved for 2 mins first, Is it safe? I was given this Great Value brand beef patty from a person who didn't like them.

I don't have a grill or stove so I decided to just microwave them. I did 1 min each side. It was brown and tasted fine. 

Just want to be sure this is safe before doing it again. Also if anyone else does this, please explain your process.
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.
