Halle Berry is constantly on the lookout for possible threats to her daughter's safety ... stalkers, abusers, etc. ... but this weekend, one thing got past Halle ... a GERM-RIDDEN STEEL POLE!
Halle and Nahla were hanging out on a ride at Knott's Berry Farm amusement park in Southern California when Nahla decided she wanted a taste of the unknown ... and plopped her tongue out on the safety bar.
Nothing a mouthful of Scope can't handle ... but seriously, GROSS!
