I assume she got 'caught' when her bags were sent thru the agriculture x-ray machine.
I general, if a passenger declares no food and happens to get sent to 'green light' and food shows up on the screen, the customs agent will ask the passenger if they have any food. If the passenger suddenly 'remembers' and says 'yes', they will not get fined. This is considered like a verbal amendment to the customs form. If they still do not remember the food, they probably will get fined.
