Salad bars?

I ate a salad from a salad bar today and I just read online that salad bars aren't the best option so I'm kinda freaking out now. The romaine lettuce was bagged and I watched the lady re-fill it so it was freshly put out. I also put spinach on it but the spinach looked pretty good and washed. I put carrots and cucumber, croutons and balsamic dressing. Just want to make sure this all sounds okay and I don't run the risk of losing my peanut :(
