Could the pet food tainting be food terrorism?

This was a Canadian company which removes it somewhat but not entirely from terrorism. No one is exempt from the terrorists tho. This reminds me of the tainted produce a few months back in California. Could be a disgruntled worker or someone seeking 15 seconds of fame. Or testing for our response. With the California cases they tracked it back to the field the tainted produce was from. That says something for all the regulation.
