Abstract - Eighty-two samples of honey supplied by American and Canadian honey producers were tested by the Hansen method for the presence of American foulbrood (Bacillus larvae) spores. Seven (8.5%) were found to be positive. It was confirmed that the Hansen method is rapid and reliable. We believe it will be useful in screening individual colonies to determine which hives should be carefully inspected and/or treated to prevent potential economic loss from American foulbrood.

Key words: American foulbrood / Bacillus larvae / honey / honey bee colony / Hansen method
