A woman charged in connection to a food-tampering incident will plead not guilty.

Tatyana Granada was in court on Wednesday morning.

She is charged with one count of mischief in connection to one of the food tampering incidents at the Oakridge Co-op.

"She is very unhappy and very distraught about being accused of this. It's created a lot of havoc within her neighbourhood so it's been hard for her," says Mark Takada, the lawyer representing Granada.

The 43-year-old was charged in March after the third incident of food tampering at the Oakridge Co-op.

In that case, metal pins were found with in deli cheese items and flatbread packages.

Takada says the Crown's case is relying on video surveillance of his client.

While the Crown will argue the video shows Granada tampering with the food, Takada will argue his client was just shopping.

"Quite frankly, the quality of the surveillance video is so-so. At least the stuff I have seen. It's certainly not the smoking gun like in other cases where video is conclusive," says Takada. "It shows my client shopping in a Co-op, handling items, putting some in her cart, then paying. It's really hard to say what it depicts."

Granada's release conditions were also amended on Wednesday. She is now banned from going near any Co-op store in Alberta. Originally she was not allowed near the Oakridge Co-op in Calgary.

Meanwhile, police are still investigating the 15 other incidents of food tampering that have happened in grocery stores in every quadrant of the city.
