Some long term studies may be necessary, as there appears to be a correlation in instances of cancer among butchers and slaughterhouse workers.

It is not known whether this naturally occurring rabbit disease is linked to BLV infection.

Leucosia quote from a USDA fact sheet, “The high individual animal prevalence of BLV reported in the Dairy study suggests that testing and culling seropositive animals may not be a cost effective method to control the disease.
