A red tide may not be harmful to humans who aren’t exposed to its toxins, but it can have a negative impact on marine life. If you eat seafood contaminated with toxins, neurological symptoms may occur and become serious.
What are those neurological symptoms?
Exposure to other neurotoxins can result in harmful effects on the brain in mammals. Memory impairment, epilepsy, dementia, neuropathy, and/or myopathy are common manifestations of neurotoxin exposure.
