technically, yes, but the danger lies more in that food can get stuck between layer lines and develop naughty bacteria
This guy on YouTube explains it great
I think even technically that only applies to pure PLA, and most filaments will have at least some additive for colour. Usually filaments blended with some other plastic are marketed as PLA+, but I don't think there's any regulation at all regarding 3d printing filament so I wouldn't take for granted that regular PLA doesn't contain other plastics/additives/contaminants. Though even if the filament contains other stuff it still might not be harmful of course.
