I'm not aware of any direct relationship between shrimp allergy (a food allergy) and penicillin allergy (medication allergy), although it could be possible that farm-raised shrimp are treated preventively with penicillin. Whether that would still be present by the time you eat the shrimp, however, I don't know.
If you are concerned, please discuss this with your doctor.
Best,
Kathi
