This was explained to me by a family member who works in the food industry for a smaller company that sells all sorts of canned goods. Part of her job was to figure out the expiration dates, and that was a completely arbitrary process that is completely unrelated to any kind of statistical chance of the product going bad before, after or around that date. She said that if it wasn't for the law it would make more sense not to have any date on the can, but because of the law, they had to put some kind of date on there.
That's not completely true. Different canned goods have best buy or shelf life dates due to many reasons. If there are spices or herbs in the product then there are inherently micro counts in the canned good, especially in nuts which dont go thru anything more than a cook of the nut itself to roast it. If its in a canned or retorted product depending upon whether the herb/spice/onion/garlic/tomato... was treated will depend upon how long it can last in a can. If the canned good goes into the can raw and cooked in the can as part of the retort there is a VERY good chance that in 18-24 months the product will start to spoil. If the product is cooked, cooled, canned and then retorted(recooked) then the shelf life will be much longer since its been thru a kill step, and then all the oxygen has been removed and a 2nd kill step has been put in process.
The thing to remember is Garlic, Onion and all spices and herbs need to be treated somehow and Steam treatment isnt a very effective way of killing most of the harmful micro organisms that make us sick. Right now, today I am on a wild goose chase for Organic spices and herbs that meet certain micro counts for topical applications. There has been a Salmonella warning issued by the FDA and a recall of MANY Organic herbs, spices and dehydrated veggies because of the lack of treatment allowed to maintain the Organic status. And to think its only Tuesday...

Its not the water than goes bad, its the leeching of the plastic that makes the water bad. Harmful chemicals thru heating and cooling will turn the water brown, make it have an off taste and aroma or just infuse carcinogens into the water itself.
Edit: Didnt mean to derail the thread, and to answer some questions, eating nuts after the best buy date or past the manufacturers date can be worse than you think depending upon what is on the nuts. If its just some Sea Salt then I wouldnt be as worried, just some rancid toppical or nut oils, they wont taste good and you will know generally from the smell. If they have something like a BBQ, Cheese, or garlic/onion seasoning just throw it away. Those all have high micro counts and depending upon who the nut company is will depend upon what type of treatment they allow on the seasoning that goes on the nuts. I have and will always use my old restaurant expression, WHEN IN DOUBT THROW IT OUT!!!
