How to address MD and MPH programs in my LOR's?

Hi. I will be applying to both MD and MPH programs separately. That said, how should the people writing my LORs address both types of programs? Would it look bad if a medical school saw "MPH" mentioned in my LOR? Would it look bad if the letter is too broad (i.e. "I recommend this student to all graduate programs")? How should I go about this? What is the technique here? Thanks in advance.
