When I was working at a gas station, someone brought in a propane tank which had expired in 1963 (or so). If 1963 and using this scheme, my score would be 96.6. | When I was working at a gas station, someone brought in a propane tank which had expired in 1963 (or so).

Propane tanks do not "expire", that is they do not go bad with time, and you do not need to throw them out after the date. The date on these tanks is when they need to be inspected for damage, as mandated by Federal and state laws. If the tank passes inspection a new date in put on and you can keep using the tank (propane suppliers can legally keep refilling it.)

:Perishable foods had expiration dates in the 1970s at least (maybe earlier in some countries and some stores). But non-perishable foods did NOT had dates until the 2000's or later. A home canned jar of pickles could have a hand written date, but this would be the date it was canned, not an expiration date. Because anyone in the 1970s who knew how to can would know if they did it right the food would not go bad. If they did the canning wrong they would not need a expiration date to know this, they would know in a few weeks, by looking through the mason jar at the food inside. Or by looking at the food and glass spread around the pantry after the jar exploded. So Megan's mom could have a loaf of bread with a 1978 date, but not a jar of pickles.

:To be fair, many items are labelled "Best Before" or "Sell By" - implying that the food item will be edible for at least some time beyond that date. Actual expiration dates on preserved food items do seem to be rarer. There are cases of canned food items from the early 1900's still being in good shape after 100+ years - and those would not have had any expiration date. But one issue is that back then, cans were made by soldering sheets of tin together - and the lead in the solder slowly leaches into the food making it unsafe to eat even though the food itself seems well-preserved. So for potential high scores, we should look to: [http://mentalfloss.com/article/555075/11-oldest-foods-and-beverages-ever-discovered The 11 oldest foods and beverages ever discovered] - except that they'd not have any kind of formal expiration date.

− | + | The legal requirements of "expiration dates" for food are less stringent than many believe. In the USA, under FDA regulations, only baby formula cannot legally be sold after its expiration date. Wording like "use by" and "sell by" is not legally binding... more like "guidelines", as Capt. Barbossa would say. [[Special:Contributions/172.68.34.64|172.68.34.64]] 15:57, 19 July 2019 (UTC) | |

I think the point that needs to be made in the explanation is both the items in the comic (a can of beans and a jar of pickles) do not go bad with time but in fact remain edible indefinitely. | I think the point that needs to be made in the explanation is both the items in the comic (a can of beans and a jar of pickles) do not go bad with time but in fact remain edible indefinitely. | ||

Canned food is first put into the can and sealed and then heated up to around 60~80 degrees Celsius. After it cools down, the label is placed on it. - sirKitKat | Canned food is first put into the can and sealed and then heated up to around 60~80 degrees Celsius.
