Can I collect epizootic ulcerative syndrome (EUS) samples for laboratory examination?

Why and where is epizootic ulcerative syndrome (EUS) a problem today?

EUS is one of the most serious aquatic diseases known to affect finfish. The disease causes high losses to fish farmers and fishermen through mortalities and reduced productivity of all susceptible fish species. Market rejection and public health concerns due to the presence of unsightly lesions provide for further losses.

EUS has been reported from at least 28 countries and from four continents (North America, Africa, Asia and Australia).

More than 160 species of finfish are susceptible to EUS. Almost a third of these occur in Southern and Central Africa.

Other indirect long-term effects include the threat to the environment and aquatic biodiversity through, for example, declining fish numbers and irreversible ecological damage.

EUS has the potential to financially decimate those who rely on fishing for income. In addition, and perhaps more importantly, EUS outbreaks threaten food security for subsistence fishers and fish farmers and consequently people’s physical health, as fish forms an important source of animal protein for people in many affected countries.

The spread of EUS across Asia from Japan and Australia where it was first identified in the early 1970s to Pakistan in 1996 and to southern Africa in 2006 is a major epizootiological phenomenon.

EUS is an OIE-listed disease, and notification to the World Organization for Animal Health (or OIE) is required in the event of an outbreak.
