Comment on Do you toss food once the date on the label has passed? Experts say that's often a waste

This is where info seems to be scant. My mother often told me: if there is mold in something with tomatoes → death… toss it. I’m sure there is a grain of truth to that but I recently tested this. I scooped out a bit of mold from tomato sauce in left-overs, and ate the rest w/out issues. I probably reheated the left-overs but don’t exactly recall.
Heard stories about some granny unwittingly using spoiled mayonaise in potato salad served to her church which killed people. Bacteria/virus/pathogens love eggs (hence why it’s used for vaccine making). So I don’t fuck w/mayonnaise but fries vendors often have big tanks of unrefrigerated mayonnaise with hand pumps. Not quite sure why that has no issues.
In any case, it would be useful to find a reliable source on what kinds of bacteria are common in what foods, and ultimately which spoiled foods are more or less likely to cause serious issues.

How you react to eating unsafe food can depend as much on you as it does on the food. What you could eat without noticing any issue might make some other person very sick and kill yet another person. It can depend on factors like how good your immune system is feeling that day, what it has experience dealing with, how good your overall health is, and what specific species makes up your gut biome. Or, counter-intuitively, sometimes if you are less healthy overall, it can mean that something doesn’t affect you as much, eg if you have gut issues that prevent you from absorbing toxins related to some pathogen, you could pass it fine while it knocks a healthier friend of yours on their ass.
For the mayo, my guess would be the ones usually not kept in a fridge likely use more preservatives, though I’d bet they also have a shorter shelf-life than the ketchup and mustard pumps. Another possibility is that it isn’t really mayo but just something that looks and tastes like it but was made very differently.
For which bacteria is present on foods, I believe that this is very region-dependent and that the supply chain will play a bigger role than the food type (though food type will affect which bacteria and fungus species thrive on it). Might see different microbe profiles based on time of year and all of them will be evolving new clades and going extinct over time. Not sure how much of an impact survival of the fittest has on what this actually looks like from year to year or decade to decade, but understanding what microbes are doing what to your food could be a moving target similar to trying to keep track of what covid clades are associated with what symptoms or traits.
