down-draught extractor fans are installed and protective clothing is worn. It is almost impossible to sterilize bone products and it would be a costly, indeed uneconomic, process. At a symposium at the Veterinary Public Health Association meeting in 1964 it was concluded that considering the widespread distribution of anthrax spores in imported animal products, coupled with the small number of cases in man, then man's resistance must be considerable. Extensive disinfection processes seem hardly justified since effective immunization is available to those at risk and effective chemotherapy for established cases. Few cases of anthrax among bone meal workers in this area have been seen since anthrax inoculation became routine. The odd case has occurred in those whose inoculation schedules had not been completed. I believe that professional gardeners should also be vaccinated against anthrax and that bone meal fertilizers should be packed in sacks carrying a prominent warning that gloves should be worn.
