What causes ciguatoxin contamination in food?

• A. Fish processing errors
• B. Cross-contamination
• C. Toxin-producing algae
• D. Improper cooking

Answer: (C)

Ciguatoxin contamination in food is primarily caused by toxin-producing algae, particularly dinoflagellates that thrive in certain coral reef environments. These algae produce ciguatoxins, which accumulate in the tissues of fish that feed on them. Larger predatory fish, such as barracuda and grouper, can ingest smaller fish that have consumed these toxic algae, leading to a higher concentration of ciguatoxins in their bodies. When humans consume these contaminated fish, they can experience ciguatera poisoning, which can result in a range of gastrointestinal and neurological symptoms. The bioconcentration of these toxins through the food web makes it crucial for seafood consumers, especially in regions known for ciguatera, to be aware of the risks associated with certain fish species. This highlights the importance of understanding marine ecology and the sources of seafood contamination to prevent foodborne illness.
