An employee of a Ferndale, Washington, Dairy Queen says she “accidentally” poured Ajax into the malt dispenser, sickening two customers, according to court documents.

Detectives obtained surveillance video and saw the employee, Dale, pouring the Ajax into the malt dispenser, documents said.

Meanwhile, officials at an Arkansas hospital reported Friday that 10 children drank windshield wiper fluid after a staffer at an Arkansas day care mistakenly put the liquid in a refrigerator and served it.

A hospital toxicologist said,

"All we know was that the individual at the day care had recently shopped and had come back to the day care with a lot of different products. This product was mistakenly grabbed and thought to be Kool-Aid and put in the refrigerator."
