Old Tinned Food

A man celebrated his golden wedding anniversary by eating a 50-year-old tin of chicken.

So whats the oldest food you've ever eaten?

I have a friend in South Africa who makes what she calls "hundred year old bread" and uses yeast that has been in her family for generations now. So I guess technically that there are still living organisms within that mixture that would be around a hundred years.

I wouldn't eat tinned chicken even if I watched it get canned.
I used to eat that awful "chicken spread" in a can. Ugghh. What were my parents thinking?

Can you imagine the preservatives engaged in an operation like that?

Here's an article about 150-year-old sourdough bread -- it even survived the 1906 earthquake!

Have you all heard of the yeast found aboard an 1825 shipwreck that was used to recreate an authentic old style porter?

Or the Norwegian brewer whose stirring stick supposedly still contained yeast from the age of the Vikings?

Or the yeast recovered from a submarine sunk in 1915?

I thought I read some living yeast was recovered from an ancient Roman shipwreck, and used to recreate their beer, too, but I can't find any online references for that.
