What could be the cause of throat and ear pain?

My first thought is ear infection. After a rough cold of 2 weeks cleared up, 3 days later I went to the Urgent Care because my ear/throat pain was so bad and it was an ear infection. They can be common with colds, you should go to the doctor and antibiotics should do the trick. If it isn't very painful it could just be a dry, agitated throat. I doubt its a food poisoning, but maybe its an allergy. Spicy food can definitely cause normal irritation in your throat though- so just keep track of if it happens every time you eat spicy food (or shrimp). Either way, you should be just fine. Good luck
