Hi, You may be experiencing an allergic reaction to corned beef. Allergic reactions occur when the immune system overreacts to a particular substance and can cause a range of symptoms. Some people can develop an allergic reaction to a specific food, and corned beef is one such food that can cause an allergic reaction in some people. The symptoms of an allergic reaction to corned beef can include swelling of the face, lips, tongue, or throat, as well as itching or tingling in the mouth. Other symptoms may include difficulty breathing, nausea, vomiting, diarrhea, and abdominal pain. It is important to seek medical attention if you experience any symptoms of an allergic reaction after eating corned beef, especially if they are severe or if you have difficulty breathing. In some cases, a severe allergic reaction known as anaphylaxis can occur, which can be life-threatening if not treated promptly. If you have a known allergy to corned beef or any other food, it is important to avoid eating it and to carry an epinephrine auto-injector with you at all times in case of an emergency. Take care.
