He performed other experiments with maggots, including one where he placed dead flies or maggots in sealed jars with meat and observed living maggots did not appear. His most famous contribution to science was the "meat in a jar" experiment which disproved "spontaneous generation". Spontaneous generation, a theory that maggots, fleas, worms and other living organisms developed from inorganic or dead organic matter, was the prevalent viewpoint of scientists for around 2,000 years, since Aristotle first posited a description of the phenomenon. In addition to his refutation of spontaneous generation, Experiments on the Generation of Insects contained Redis detailed drawings of a large variety of insects, eggs, and maggots, such as these below. Francesco Redi, (born Feb. 18, 1626, Arezzo, Italydied March 1, 1697, Pisa), Italian physician and poet who demonstrated that the presence of maggots in putrefying meat does not result from spontaneous generation but from eggs laid on the meat by flies. Although the meat in all of the flasks putrefied, he found that only in the open and uncovered flasks, which flies had entered freely, did the meat contain maggots. -. The first serious attack on the idea of spontaneous generation was made in 1668 by Francesco Redi, an Italian physician and poet. Within a century of its invention in 1595, .

He proposed a toxin-antitoxin interaction called an Ehrlich phenomenon and also introduced methods of standardizing toxin and antitoxin. In 1837, Italian zoologist Filippo de Filippi named the larval stage of the parasitic fluke "redia" in honor of Redi.
