A woman who was accused of tampering with food at a Calgary grocery store has been found guilty.

Tatyana Granada was charged with mischief and trespassing after metal pins were found in bakery items at the Oakridge Centre Co-op store back in 2010.

The incident sparked fear in the city and made consumers question food safety.

Before the tampering incidents, Granada, 44, was banned from the store for allegedly shoplifting.

Granada was found guilty of four counts each of trespassing and mischief.
