How are anti biotic resistant super bugs created?

    There are a number of ways that super bugs evolve.  The first occurs in a hospital setting.  Bacteria that live in hospitals are constantly exposed to antibacterial soaps, antibiotics and other chemicals.  Bacteria are able to grow, reproduce, and thereby evolve very quickly.  Essential we are selecting for bacteria that are most tolerant to these medicines and cleaners.  Another source is feedlots.  Here cows are kept in pens filled with feces.  These feces are heavily contaminated with ecoli from the cow’s unnatural diet of corn and artificial silage.  The meat is easily contaminated by ecoli in the on site slaughter house.  Ground beef amplifies the problem as meat from many sources is combined increasing the risk for contamination.  This problem is the reason that the government has initialized the irradiation of beef. Contaminated cow feces are also used on crops.  This is likely the cause of the recent Listeria outbreak in cantalope.

    As bialowieza mentioned, antibiotic-resistant bacteria will develop in an environment with lots of antibiotics such as hospitals or feedlots. It is also necessary for them to undergo some sort of genetic mutation. Genetic mutations happen randomly when a bacteria copies its DNA for reproduction, and some genes can be copied and shared with other bacteria. Bacteria do some very strange things with their genes, and I recommend reading this web-page to find out more:
