Here's some material for Karl. I've only gotten food sick twice in all my trips to Viet Nam. First time I bought some peanuts from vendor while I was sitting at a Cafe. WET PEANUTS, yes Karl wet nuts , not roasted. Made me sick for a day. Second time was just a few weeks ago. Chins Mom gave me these little red berries, had three seeds inside. Never seen them before. No, I didn't eat the seeds. But I ate probably 20 of the berries. Also made me sick for a full day. Other than that....All good in Viet Nam...
