Is food sickness common?
It can be. You need to ensure that it is freshly cooked and do not eat fruit or vegetables that has been pre cut. Tap water is unsuitable for drinking, restaurants will provide filtered water for free, but you need to be vigilant to brush your teeth with bottled water (bottled water is very cheap) and be aware that salads unless requested are most likely rinsed with tap water. However, your immune system will build resistance as you stay and you may be able to eat more freely. Upon arrival Blood Foundation will point out trusted restaurants with fantastic food to help you thoroughly enjoy your Thai experience.
