Brain Edema Caused by Pig Blood Dishes: Why We Need to Be Alert

A recent case of brain edema in a man in Vietnam serves as a crucial wake-up call for us all. The incident involved a man in his 40s who was rushed to the hospital in critical condition with severe brain edema and coma, all due to a traditional dish he frequently enjoyed. This case highlights just how significant the impact of our food choices can be.

Emergency Treatment and Recovery Process

The man was admitted to the emergency room at the National Hospital for Tropical Diseases in Vietnam, presenting with a high fever and decreased consciousness. Diagnostic tests revealed he had acute bacterial meningitis caused by Streptococcus suis. Medical staff immediately placed him on a ventilator and initiated emergency treatment, including antibiotics to combat the bacteria and medication to reduce brain swelling. Fortunately, after four days of intensive care, the swelling in his brain subsided, and he regained consciousness. He is currently recovering in a general ward.

The Dangers of Streptococcus suis

Streptococcus suis is a bacterium commonly found in the tonsils and respiratory tracts of pigs. When it infects humans, it can lead to severe illnesses. Symptoms of infection include high fever, severe headache, vomiting, decreased consciousness, and seizures. Meningitis, in particular, can be life-threatening if not treated promptly, making it a condition that requires extreme caution.

The Risks of the Traditional Dish 'Tiet Can'

The dish the patient frequently consumed was a Vietnamese traditional delicacy called 'Tiet Can'. This dish is made by coagulating uncooked pig or chicken blood, typically mixed with minced meat, herbs, and peanuts. However, because it uses raw blood, the risk of bacterial infection is extremely high. While cultures like Korea also consume blood products (e.g., 'seonji'), they are usually thoroughly cooked, significantly reducing the risk. In contrast, 'Tiet Can', made with raw blood, poses a substantial risk of exposure to bacteria or parasites in the blood.

Prevention and Response Measures

Experts emphasize that while Streptococcus suis can survive in warm environments, thoroughly cooking food kills the bacteria, making it safe to consume. Therefore, it is crucial to avoid eating raw pig blood or meat, whether traveling abroad or in daily life. Furthermore, if you experience symptoms such as high fever accompanied by severe headache, vomiting, changes in consciousness, or seizures, seek medical attention immediately.

This incident serves as a stark reminder of the importance of our food choices. Maintaining safe eating habits is paramount to protecting our health.
