Not to drive the subject into the ground, but I've been there. While a student a couple of years ago <g> in Spain my friend a teacher from Maryland and I decided to have an ordinary type meal after living on Tapas and Paella and we had a ham sandwich and a bowl of tomato soup. The story was pretty ugly. We fortunately had decided on a splurge as Spain was cheap (OK it was more than a couple of years ago <g>) and we had a room w/private bath. Thank God as we were in sad shape from every orifice possible only being able to crawl from our beds to the lu. I am not sure exactly how long we were in this condition as we both would pass out as in coma I guess. I managed to crawl down to the post office to get a message to my friend I was to meet in Paris that I wouldn't be there. I was standing in line at the Palace of Communications in Madrid and the rest is history--out cold. Emergency medical care for both my friend and I and we survived. It wasn't pretty and a very close call, and we both had severe after affects for years. I remember one thing they had us do was eat lotsa lemons afterwards, don't know why. So be careful and don't take unnecessary chances. I don't can tomatoes or chiles, but I do freeze and pickle and dry. Our theory is if in doubt--don't. I have thrown out all sorts of maybe fine things just to be on the safe side. I must admit we don't refrigerate all our hot sauces after they are opened----they don't in India, Thailand, or China or a host of other places. What to do? Guess we are building up our stamina. You wouldn't believe some of the things I have eaten in China, India, etc., but we won't go there. Mary-Anne
