That is the approximate number of cases of food borne illness, a good majority of them from meat/sea food products. The numbers are determined (in some cases) by feeding paid volunteers a given number of bugs and then watching their responses (fever, nausea, vomiting, diarrhea, cramps, etc.) both clinical and biochemically. By using these techniques, we have achieved the high standard of living that we enjoy. As far as risk goes, until December of 2020, I was told over and over again that there was no risk to a global pandemic happening again. Guess what?
