- Check with local authorities for which species and waters are safe for harvesting and fishing to prevent harvesting seafood products from areas with high 
concentrations of toxins. 

- Check for toxins in the seafood especially for tropical seafood products for every batch before processing. 

- Cooking the seafood products will remove some of the toxins

- Exercise good hygiene practices during processing

- Practice depuration or the dilution of toxins

A poison can be as basic as an ion or atom that interferes with a cell adversely. The type of complex molecules such as the proteins found in snake venom may also be a toxin.

Puffer fish poisoning toxicity results from consumption of incorrectly prepared puffer soup, fugu chiri, and sometimes from eating raw puffer meat, sashimi fugu. 

Symptoms generally occur 10-45 minutes after eating the pufferfish poison and begin with numbness and tingling around the mouth, salivation, nausea, and vomiting.
Symptoms may progress to paralysis, loss of consciousness, and respiratory failure and can lead to death.

Treatment: 

• Vomitting should be induced so that the toxins can be passed out of the body --> only when the toxin is alert and awake (3 hours after consumption) 
• Almost no known antidote :(

Tetrodotoxin is an extremely potent poison (toxin) found mainly in the liver and sex organs (gonads) of some fish, such as puffer fish, globefish, and toadfish (order Tetraodontiformes) and in some amphibian, octopus, and shellfish species. 

Treatment: 
There is no known antidote. The mainstay of treatment is respiratory support and supportive care until the tetrodotoxin is excreted in the urine. Activated charcoal and/or gastric lavage can be done if the patient presents within 60 minutes of ingestion.]]> 2020-12-03 06:39:26 UTC https://padlet.com/19008858/20vbp7lgnxfk9okp/wish/982708335 19008858 https://padlet.com/19008858/20vbp7lgnxfk9okp/wish/982710338 Histamine poisoning
Tuna is a  scombroid which means they have high levels of histidine in their body. Histidine is converted to histamine by microbes. This can be due to time temperature abuse during handling which results in the proliferation of microbes and result in more histamine produced. Histamine is also resistant to cooking, smoking, canning and freezing which means that the best way to prevent histamine poisoning is to watch out for time temperature abuse, and microbial growth in general.

Symptoms occur with 5 to 30 minutes but some can show after 2 hours. Generally they do not persist for long, a few hours or a day at most. Rarely do they persist for more than a day.

Treatment 
Antihistamine is usually used to treat this. ]]> 2020-12-03 06:40:33 UTC https://padlet.com/19008858/20vbp7lgnxfk9okp/wish/982710338
