This initiates an immune response to release antibodies to attack the protein. The next encounter of the individual to the shrimp protein, the immune system releases histamine which is the substance responsible for the development of skin rashes along with other symptoms.

Remember that this is a serious reaction that entails immediate medical care. In case the individual ends up with skin rashes right after eating shrimps, he/she must not eat it again until the allergy is confirmed. Allergic reactions can progressively worsen after every exposure.

  • Abdominal cramps
  • Slurred speech
  • Severe wheezing
  • Vomiting
  • Difficulty breathing
