Three weeks ago, my baby, a 21-month-old boy, drank pasteurized milk but it had expired several days ago and unfortunately we realized it later.
within the next 5 days of the incident he underwent a stool mayer test and a stool culture and no germs were found in either test.
We also did a blood test for listeria twice. these tests were negative too.
To date he has not shown any symptoms of infection from the incident.
Is there a case nevertheless to have listeria?
I ask because I read that the symptoms of this bacterium appear up to 2 months after infection in some cases. but we had 2 negative blood tests!
Does anyone know anything?
Thank you very much.
