Having spent some time in the food industry, the possibility of having a finger in the chili is truly remote. I suspect she put it there and will be sued by Wendy's.
Food processing is the domain of truly paranoid people. everything is tested, looked at, sealed, measured, etc.
This woman is in for a world of hurt.
Being an attorney and having seen some ingenious and not-so-ingenious methods con artists will use to try to extort money from a deep-pocket, I am hard to convince that a claimant like this has a legitimate claim. I am admittedly biased against them.
In my earlier years as an attorney I had shady claimants try to retain me for similar, though not nearly so lurid, claims. I send them right back out the door. I passed up easy money in some cases, but that's okay.
