<li>The U.S. Food and Drug Administration approves the first genetically engineered drug Humulin, a form of human insulin produced by recombinant E. coli bacteria. Prior to the development of synthesized human insulin, patients were dependent on animal insulin, which was more costly, less accessible, and sometimes caused infection. Humulin is identical in chemical structure to human insulin.

<li>GloFish, a GM fluorescent fish first developed in 1999, is introduce to the U.S. market after being available in Taiwan earlier in 2003. Since their introduction, there have been no reports of any ecological concerns associated with their sale, though they are illegal in California due to a regulation that bans all genetically modified fish. They are also banned in Canada and within the EU.

<li>The FDA receives an application for the first genetically modified animal for human consumption. The AquAdvantage Salmon, created by AquaBounty Technologies, has a gene from the ocean pout and a growth hormone from a Chinook salmon, which allows it to “reach market size twice as fast as a traditional salmon”. The FDA determines more research is necessary to assess the safety of genetically engineered animals intended for human consumption.
