General Comments

A bacterial disease with a wide host range and many sub-species and strains, including those that could thrive in cooler climates, showing different levels of pathogenicity. Although regulated, there is some concern about the risk of introduction. Should an outbreak occur, there would be a need for eradication action which would result in environmental and social impacts.
