Irrigating food crops with water containing cyanobacteria blooms

Primary inquiry: Small horticulture growers have been watering their crops with surface water containing a cyanobacterial bloom, before selling their crops at local markets.

1. Can irrigation of food crops using surface water affected by cyanobacteria blooms result in bioaccumulation of cyanotoxins in these crops?
2. Can cyanotoxins bioaccumulate to a concentration that might cause a public health concern?
