It is important to the protection of human and animal health to be able to recognize the gross appearance of cyanobacteria. The two photos here are of HABs caused by cyanobacteria at lakes in Minnesota and New York. The blue color of cyanobacterial blooms, which is often most evident at the shoreline, develops as the organisms degenerate. Microscopic examinations of cyanobacterial cells and cyanobacterial toxin analyses by individuals with expertise in this area are also of great value.

The highest possible score is 800. In addition, only one program is on probationary accreditation and falls below a 50 percent, three-year pass rate on the VTNE, not two as originally stated.
