Last Sunday night I had Mahi-Mahi at a restaurant in Philadelphia. My stomach was churning when I left the restaurant and within 1 hour, I developed the worst case of diarrhea, the need to vomit (but I couldn't), stomach pains similar to labor pains, sweats and then chills from scombroid poisoning. I was sick for at least 12 hours with the same symptoms. I was able to return to my home state of New York the next day and went immediately to my primary doctor who diagnosed scombroid poisoning. One week later, I am still not 100 percent.

About 15 minutes after eating pan seared yellow fin tuna, I got a sudden intense headache, and started to feel flushed from scombroid poisoning. I developed what looked like a sunburn on my upper torso, and felt really crummy. My heart was also racing. After inducing vomiting, I felt much better, with only a slight headache, and the rash disappeared.

I had a headache within minutes of eating tuna. I went very flushed. My heart was racing and I felt very anxious. I had diarrhea for about 2 hours with fever and chills. The whole scombroid poisoning episode lasted about 4 hours.

Tonight I had tuna steak. Within a couple of minutes of my first bite my gums felt sore and inflamed. I had no other symptoms of scombroid poisoning so I continued to eat. But then started to feel hot and itchy and red flushes appeared all over my body. By the time I'd finished, my heart was racing, I felt faint and short of breath so I went for a nap. I awoke around 30 minutes later with awful stomach cramps and tight bloating. My husband felt the same 1 hour after eating the tuna.

Yesterday I went to a restaurant and ate tuna topped with a cheese sauce. I started feeling bloated and gassy shortly after but ignored it because I had to go back to work. Fast forward to that night, I had extreme cramping, watery diarrhea in between large, hard feces (constipation), and a fever. This morning I woke up with hives, and my diarrhea now has a very pungent and odd smell. Obviously feces smells bad but this is an odor I've never smelled before. I have issues staying hydrated normally so after work tonight (couldn't get off so I'll have to just push through it) my doctor recommended I go straight to the hospital for an IV for Benadryl, Zantac, and fluids. Definitely saying something to the restaurant about this scombroid poisoning!

I had all these symptoms of scombroid poisoning after eating ahi tuna this weekend. It went away after a few hours.

After eating a lunch of tuna carpaccio and wahoo, at the end of the lunch I noticed my face, shoulders, neck and arms were going red like sunburn, although I hadn't been outside for long that day and had sunblock on. The flushing from scombroid poisoning went down after around 3 hours thankfully.

I had a racing heart and dizziness about 3 hours after dinner. Dinner was a Scottish farm raised salmon, supposed to be of the highest quality from the local health food store. That was followed by cramping and diarrhea which had me up until 5:30 am. This morning I am flushed and itchy. I did not seek medical attention as symptoms of scombroid poisoning are relatively mild.

I believe I had a scombroid poisoning from shrimp, about 20 to 30 minutes after eating shrimp (prepackaged, from supermarket). I have never had any allergies. I later discovered it was past its use by date, but as it was in a spicy sauce, I didn't notice any odd taste. I started feeling hot and flushed, developed urticaria and some swelling, mostly noticeable on lips and fingers. I decided to go to the hospital, on the way there blood pressure dropped and I was very dizzy, also vision went blurry. I was treated with steroids, and possibly antihistamines. Subsequent allergy testing has not found any allergies, neither by blood test or skin prick. I have not eaten any shellfish since then to confirm though.

I ate an imitation crab dip that was normally served heated. I ate three bites and suddenly got ill and my throat and nasal passage closed up. My face started swelling and I had to be rushed to the emergency room. I was given an anti-histamine in the ambulance for scombroid poisoning and after several hours I started feeling more like myself. It was a scary reaction to a dip that I normally love.
