I had enjoyed escargot several times on one Celebrity cruise, and I had never had an allergic reaction. The escargot were served with really pungent garlic butter. When I went on a Princess cruise, I had escargot again and the garlic was barely detectable. About 3 hours later, I had a severe allergic reaction and was rushed to the medical facility on board. I was hooked up to an IV, had an electrocardiogram, shots of decadron and prednisone, and had a nurse at my side all night. My face was swollen to the shape of a soccer ball, my lips enormous, the interior of my mouth cracked and oozing. This was totaly unexpected, and I haven't risked escargot again. The bill at the infirmary was over $1400. Nobody else at our table suffered from ill effects. On the menu, the escargot were described as mountain escargot. On Celebrity, just escargot. Wonder if there is a difference, and if heavy garlic somehow prevents allergies.
