A two-year-old girl who found a used condom in the eating area of a McDonald's will have to undergo STD testing.
A Perth couple were "sickened" to find their toddler had picked up the black item about 6pm Friday night at the fast-food outlet in Warnbro in the city's outer-south.
The mother, who only wanted to be known as Wendy, told 10 daily she went back to the counter to order something when her husband spotted their daughter sucking on the condom.
"I ran into the bathrooms, washed her mouth and hands and came out and gave her a drink. We were terrified," she said.
"I am really angry and sickened ... I haven't slept. I have been feeling overwhelmingly guilty for taking her there in the first place."
