I really don't see how accidental contamination during production makes Homeopathy more harmful than anythign else that can be contaminated. Would you also conclude that "Chinese food is actively harmful?" because someone somewhere made some dim sum that contained things it shouldn't?
Homeopathy is harmful because it's a bunch of patent nonsense that does nothing and people spend billions on it that could be used for something productive.
