In the processing of poultry, equipment, instruments, apparatus and/or water used in such processing, and/or carcasses and/or parts of poultry resulting from the processing of poultry, are disinfected with aqueous solutions of certain halogen-based microbiocides, especially certain bromine-based microbiocides. Described are the particular microbiocides used and the substantial advantages of using such materials, in some cases as concentrated solutions and in other cases as dilute solutions.
