So far, tilapia lake virus (TiLV) has affected six countries in South America, Asia and the Middle East -- but the United States has, until now, managed to avoid any issues surrounding the disease. 

If the World Organization for Animal Health (OIE) lists TiLV as a "reportable disease" -- which University of Florida's Aquaculture Expert Craig Watson told IntraFish is likely to happen in the next six months to a year -- that could change quickly. 

If TiLV is indeed listed as "reportable," the Canadian Food Inspection Agency (CFIA) will require import health testing for susceptible species coming into Canada as live fish, Watson said.
