Blair Wickstrom, publisher of Florida Sportsman magazine, examines the green algae congregating in a boat basin and canal off the South Fork of the St. Lucie River Wednesday near the Florida Sportsman office in Stuart. Despite previous toxic algae outbreaks in Martin County in 2005, 2013 and 2016, this year has been the worst for this location, prompting Wickstrom to close the magazine&#39;s office for the safety of the employees after they began developing respiratory problems. &quot;You have long-term health issues with your exposure to the blue-green algae and microcystin toxins. It&#39;s just not clear (if) the airborne exposure is going to lead to ALS or Alzheimers,&quot; Wickstrom said. &quot;You cannot just bury your head in the sand and wish it away because it&#39;s continuing to get worse.&quot; To see more photos, go to TCPalm.com.
