I would not call this a travel warning but just be careful when you eat food right now. Since the tourism is not on its normal peak the restaurants are doing very bad. Some restaurants are keeping the food a bit longer then they should since they have no guest. When you eat make sure the restaurants have many guest and a restaurant packed with Thai people is normally a good sign.
Really smell your sea food if you need to eat it and do not eat salad dishes. Thai food is normally safe since it is very hot but as i said we do not live in normal times right now.
I got food poisoned just two days ago and it knocked me out for one day, i had fever chills and did all kind of nasty things to the toilet. If you do not get better in one day visit a hospital.

Actually not a bad warning, recently I went to a seafood restaurant, tables on the street style which is local to me and I go there many times. I ordered some oysters which i regularly do from this place and never had any trouble but this time they did look a bit sorry for themselves and against my better judgement i ate them regardless… Suffice to say I had some regrets!!
