Likely not: It really depends on the amount of bacteria getting into your system if the item you ate has it. Please remember: 1. Abx are NT to be considered preventative medicine. 2) Not every food item will have Listeria. 3) Go see the doctor if you think you have Listeria. Unpasteurized cheese, deli meats, and milk products are considered at risk foods.

Listeria and amox: Listeria is typically sensitive to amoxicillin. Though not recommended, having amoxillicin in your system can limit your risk of developing an internal infection. So, the antibiotics will likely work to prevent infection in you.

I agree that prophylactic antibiotics is not a recommend practice, especially in a young patient. The antibiotic received just so happens to cover Listeria.
