Can you eat molded beef jerky?

Basically my mother makes her own beef jerky. She marinates the slices of beef then leaves it out in the sun for it to dry. I use to eat these a lot before watching the process. Recently I saw that the beef were starting to mold which completely disgusted me therefore, stopped me from eating them since. Of course, I pointed this out to my mom and she insists that it's ok. She eats them pretty often and what she does is she cooks it in the oven or fry them in a skillet. And I've never seen her get sick from it. But the thought of mold just makes my stomach turn. My question is, is this abnormal? Can you get sick from this?
