I think so.

As I understand the problem, one ingests live enteric bacteria to which one's particular intestinal tract is unacclimated. The new kids on the block grow unrestrained and release substances toxic to the new habitation. The toxins stimulate the bowel to evacuate the digestive tract and raise the body temp to kill the unwelcome guest. After a few generations of natural selection (under ideal circumstances, bacteria can divide a couple of times a day) the invaders set-up permanent residence by being less obnoxious.

Those original bacteria were probably very happy and causing no symptoms in their original host. The host went to make poopie in the rest room and failed to do as his mommy taught him -- scrub hands with soap & warm water covering both entire hands for at least 15 seconds and rinse thoroughly with warm water.

The poopie-handed guy went back into the plant and did something like ... oh reassemble a recently, properly, and thoroughly cleaned meat grinder using his poopie hands.

Extremely Important! Not all pathogenic bacteria are rendered harmless by cooking.

This is why we should never, ever eat food from swollen cans or from jars of food that give-off gas when opened. Also sniff freshly opened cans & jars. If it fails the sniff test, discard it. Cooking will NOT render it harmless because the anaerobic bacteria have been busily at work in the can or jar, producing extremely toxic substances as a biproduct.
