My stomach started to hurt last night and kinda subsided. I woke up extra early today because I could not stop sneezing. Had a few cups of coffee and have been hungry all day but then my stomach started to hurt again. I was bored and got on the FDA website just to see the recent recalls. Well turns out the shredded lettuce I bought was on there for listeria. We ate some I believe Friday night with tacos. I looked up listeria and it causes v*. And it says symptoms can last 7-10 days. I'm freaked out about it. I didn't eat much just 1 taco but I ate the lettuce and I don't know how much you need to ingest to become ill with it. I'm freaking out right now and need advice.
