Ten people have been charged after $3 million in knock-off prescription drugs such as fake Viagra and plush toys stuffed with dog fur were seized in raids in Toronto-area raids.

Project Consumer Safety is one of the largest raids in the history of Toronto police, who were aided in the investigation by Peel and York region police, and the RCMP.

Beauty products, cigars and auto parts were also among the wide variety of items seized in the past two weeks.

"The success of this investigation included the arrest of 10 persons," said Staff Insp. Bryce Evans.

The public is being warned to check products, looking for labels that are missing or spelled incorrectly.

The vast majority of the seized items were made in China, police said during a Monday morning news conference.

Along with counterfeit Viagra, other knock-off erectile dysfunction drugs recovered by police are fake Levitra and Cialis.

"I don't know anyone who can condone the sale of counterfeit medication. This can and will make you ill and possibly kill you," said Det. Rob Whelan.

The seizures also uncovered plush Angry Birds toys containing rat droppings and dog fur.

Ten people have been charged with several offences, including:

Fraud over $5,000.

Possession of property obtained by crime.

Trafficking-related charges.

Police said about a third of counterfeit goods pose a serious safety risk, from poorly built electronics that could be a fire hazard to plush toys stuffed with everything from dog hair to rat droppings.

Det. Const. Andrea Chedas offered a plan for anyone wondering if a product is the real thing.

"How do I know? If that's the question, the answer is: 'If you've gone to a place, and the deal is too good to be true.'"
