Key points
- A common bacterium in pigs, Streptococcus suis, can cause severe meningitis in humans by invading the brain.
- Scientists have identified the specific protein, HtpsB, that the bacteria uses as a 'molecular key' to breach the protective blood-brain barrier.
- The primary risk of transmission to humans is through handling or consuming raw or undercooked pork products.
- Thoroughly cooking pork to an internal temperature of at least 145°F and practicing good kitchen hygiene are the most effective ways to prevent infection.
