Medical maggots are available only by prescription in the US and the UK. Eclipsed by the discovery of penicillin, maggots now may turn out to be effective when anitbiotics stop working. Although the FDA hasn't yet decided exactly how to classify maggots, they are generally considered to be medical devices. The BTER Foundation (BioTherapeutics Education and Research) offers maggot therapy workshops, but no special certification is currently required to use them. As beneficial as they are, their use is not always indicated. And when they showed up on their own in a subacute care facility in Chicago, the patient sued for "at least $50,000".
