I don't know what you mean by "some frequency"--I assume from the uneducated post you answered and the rest of your answer that you meant "not uncommon". However, Tierney, et. al. in "Current Medical Diagnosis and Treatment" (the only up to date medical text I have here at home) describe even occupational infections as "rare". I do have a Harrison's and they do not use the term "rare". But I don't know if I would use the phrase "with some frequency."

I don't want to argue over semantics, beyond saying that I wasn't talking about this country specifically, and my real point was that people do get anthrax without being the target of biological warfare or terrorism.

I might have phrased it better except that I was concerned mainly to counter the suggestion that this must be the result of an intentional act.
