I know this isn’t food illness related but Odor is big business. In the solid waste management business lawsuits over odor have been filed across many states for multimillion dollar settlements. Subjectivity is high and devices like “Scentometer” and “Nasal-Ranger”(I could be mistaken with this particular name) exist to help detect and quantify odors.

If it can “sniff out” the food poisoning like the ppb of a VOC generated from one bacteria, that could be amazing. I’m sure most of us have had a food poisoning incident and I would certainly have loved to avoided that event. 🤢
