Spam, Specially Processed American Meat Hormel introduced Spam on July 5 1937 and entered modern markets. Spam consists of Pork shoulder,Ham salt,water,potato starch,sugar and sodium nittrrate. Shoulder of pork never sold well so the inception of a canned meat was created and used thru all conflicts WW2 Korea Vietnam and Persian Gulf wars and even the Cold War. Due to the high salt content SPAM should not be consumed regularly as it can lead to health problems such as high blood pressure and cardiovascular disease. SPAM can be left on the pantry shelf for up to 5 years but once opened it needs to be eaten within 4 days and can be kept fresh in an airtight container for a week. Spam is not the same as corned beef as that contains Beef Brisket. Spam can be used all sorts of ways and in Japan it used to be only available in Import stores and can now be found as in Spam rice balls and is a regular food in that country. Spam is a staple food since WW2 and Hawaii consumes 7,000,000 cans of the meat averaging 5 cans per person a year. Hormel has made 9,000,000,000 cans of Spam and the USA eats more Spam followed by Korea. I like to make Hawaiin Pizza with Spam and frying with eggs to make a sammie is good too. Peace,BigT
