Is Your Nose a Reliable Detector for Food Safety?

AI Thread Summary
The discussion centers around the reliability of using one's sense of smell to assess food safety, particularly in relation to expiration dates. Participants express a general skepticism towards these dates, noting that they often err on the conservative side and that food can sometimes be safe to eat even if it has a slight odor. The conversation highlights the importance of caution, especially considering the risks of food poisoning. It is acknowledged that individual sensitivity to smell varies, and while humans may not compare favorably to other animals in this regard, a developed sense of smell can still be a valuable tool. Concerns are raised about contamination, as food that appears fine can still harbor pathogens like E. coli. The discussion also touches on the sensory capabilities of aquatic animals, suggesting that they too have mechanisms for detecting food safety, albeit differently from humans.

Wow. Ever since survival school, I've been somewhat ignoring the dates on various items, trusting my nose, but have still erred on the side of science (if it's past the due date, it's out). Over the years, my nose has confirmed the fact the dates usually err on the conservative side, and on a few occasions, my nose has failed to err on the side of trouble (meaning I didn't see things coming). Now modern science is confirming that my multi-million-year-developed sense of smell is worth something after all?

This morning, I threw out six fantastic-looking breakfast steaks which had but the slightest whiff of "eh..?" After all - what's $18 among friends? Thankfully, we grillled new steaks instead. The eggs were just fine

Yep, the nose is an impressive little nubbin of brain, but I agree that to err on the side of caution is wise. Short of actually dying, food poisoning is the worst... I mean... the one time I had it I thought, "I don't want to die, but if this is going to kill me let me die NOW, and not have this go on!

The sense of smell can vary a lot with genetics. Some people are much better smellers than others, and we're all pretty terrible compared to most other animals. I would agree that it's better to err on the side of caution, unless you're about to die of starvation.

Expiration dates should be viewed with some healthy skepticism. They're based on the average time it takes for the food to spoil since the date it was packaged. This is also assuming the lot wasn't contaminated in the first place. Food that doesn't smell bad can still make you sick, like ground beef contaminated with E. coli. Other foods that do smell a bit ripe may be perfectly fine to eat, like many cheeses.

In regards to the gulf, don't many of the animals also have a sense of smell? Humans aren't the only picky eaters of the animal kingdom.

Edit: It would probably be better to say "sense of taste" when referring to aquatic animals.

They certainly do, but they may well not say to themselves, "that smells like aromatic hydrocarbons, I'm not eating that crab!"
 
https://www.nhs.uk/mental-health/conditions/body-dysmorphia/ Most people have some mild apprehension about their body, such as one thinks their nose is too big, hair too straight or curvy. At the extreme, cases such as this, are difficult to completely understand. https://www.msn.com/en-ca/health/other/why-would-someone-want-to-amputate-healthy-limbs/ar-AA1MrQK7?ocid=msedgntp&cvid=68ce4014b1fe4953b0b4bd22ef471ab9&ei=78 they feel like they're an amputee in the body of a regular person "For...
Thread 'Did they discover another descendant of homo erectus?'
The study provides critical new insights into the African Humid Period, a time between 14,500 and 5,000 years ago when the Sahara desert was a green savanna, rich in water bodies that facilitated human habitation and the spread of pastoralism. Later aridification turned this region into the world's largest desert. Due to the extreme aridity of the region today, DNA preservation is poor, making this pioneering ancient DNA study all the more significant. Genomic analyses reveal that the...
Whenever these opiods are mentioned they usually mention that e.g. fentanyl is "50 times stronger than heroin" and "100 times stronger than morphine". Now it's nitazene which the public is told is everything from "much stronger than heroin" and "200 times stronger than fentany"! Do these numbers make sense at all? How do they arrive at them? Kill thousands of mice? En passant: nitazene have already been found in both Oxycontin pills and in street "heroin" here, so Naloxone is more...
