The Reregistration Eligibility Document (RED) will address the eligibility for reregistration of products containing hydroxytetracycline monohydrochloride and oxytetracycline calcium. Oxytetracycline is an antibiotic drug produced by the actinomycete Streptomyces rimosus. It is also registered to prevent the growth of, or control bacterial and fungi diseases and mycoplasmalike organisms in nectarines, peaches, pears, coconut and pritchardia palms and as an antifoulant added to paint to prevent the growth of barnacles. There are registered products containing hydroxytetracycline monohydrochloride and oxytetracycline calcium, but none with oxytetracycline, per se. Therefore, the Reregistration Eligibility Document (RED) addresses only oxytetracycline calcium and hydroxytetracycline monohydrochloride, even though some of the studies supporting the RED decision were conducted with the oxytetracycline base.
