A Regina woman claims she became violently ill last fall after drinking a cup of McDonald's coffee that she claims was contaminated by "human feces."

She's suing both the restaurant chain and Saputo Foods Ltd., the company that supplies its coffee creamers, according to a statement of claim filed with the Court of Queen's Bench in Regina.

Cheryl Mandziak said she made a disturbing discovery in August, 2008, after picking up her morning coffee at the McDonald's outlet at 924 Victoria Ave. East in the east end of the city.

After adding cream and drinking more than half the coffee, she found something "round" floating in it, she said in the statement of claim. She said she subsequently came down with diarrhea and severe abdominal pain that required medical attention.

Mandziak said she had the remains of the coffee tested by a lab, which indicated several contaminants, including "human feces." She's seeking money for loss of income, health expenses and other damages, although no sum was mentioned.

None of her claims have been proven in court.

Both McDonald's Restaurants of Canada Ltd. and Saputo Foods have denied the claims.

"We believe the allegations are totally without merit and we completely dismiss this claim," McDonald's said Tuesday in a news release. "McDonald's will vigorously defend its position in court."
