Would you buy food from someone who is subject to cottage food law in Maryland?

From what I understand it is baked goods prepared in a residential setting, so there is no health department inspection or food safety training. It’s just your neighbor selling cookies. There is something similar in Virginia but it requires an inspection, I think.
