FITCHBURG, Wis. -- A 2-year-old child in Fitchburg went to St. Mary's Hospital after drinking a small amount of bleach.

The incident happened on King James Court when the child's mother borrowed a cup of bleach from a neighbor and set it on the counter, WISC-TV reported.

Fitchburg police said that it appears to be an accident.

Poison control experts said that cases like this are the most common, WISC-TV reported.

In fact, most childhood poisonings happen while a product is being used by an adult. In these cases, experts said that even the best child-resistant lids don't help because they're usually not on or not on securely.

Even when these lids are on containers and meet federal standards, Donna Lotzer, poison education coordinator at the University of Wisconsin Hospital Poison Prevention Education Center, said that the lids aren't absolute protection.

"It's supposed to take enough time so that the adult, who is hopefully nearby, can find out what's going on and stop them from gaining access to the container," Lotzer said.
