A study by researchers at UC San Diego found that 93% of freshwater game fish tested in Southern California were infected with two types of trematodes, which can pose significant health risks if consumed by humans. These parasites, found in various fish species including bluegills and bass, can cause health issues ranging from gastrointestinal distress to severe complications like heart attacks. As this problem extends beyond California to other states, it underscores the importance of fully cooking or properly freezing fish before consumption to eliminate the risk of infection.
Nearly every single freshwater fish in Southern California may be riddled with parasites that could cause serious health issues in humans. Researchers found 93% of examined fish carried trematodes.
The two flatworm species discovered can cause stomach issues, weight loss, and fatigue, but severe infections may lead to heart attacks or strokes in humans.
Ryan Hechinger states, 'These parasites are here in the US, and they're infecting fish that people are eating,' emphasizing the seriousness of the situation.
To eliminate the risk of parasites, cooking any fish caught in affected waters thoroughly or freezing raw fish for a week is recommended.
