Born in 1943, Larry R. Beuchat was raised by Ella Jayne (d. May 6, 2019) and Raphael Beuchat (d. April 1, 2014) in Guys Mills, Pennsylvania. [5] [6] [4] He graduated from Penn State University in 1965 with an undergraduate degree from the College of Agricultural Sciences. He attributes his education at Penn State as inspiring him to pursue a career as a food science researcher. He completed master's and doctoral degrees from Michigan State University. [4]
Beuchat's career as a researcher began at Quaker Oats, but his work as an academic began at the University of Georgia. According to Penn State, he was the third most-cited agricultural scientist in 2005. [4] At the University of Georgia, Beuchat has focused on the microbiology of plant-based foods, molds and pathogens, and food safety. He has authored five books and 530 journal articles. Beuchat has received many recognitions and awards. In 2001 he received the Partners in Public Health Award from the Centers for Disease Control and Prevention for his work on Salmonella outbreaks associated with raw tomatoes. [7] In 2002, the Department of Food Science at Penn State University honored him with the "Outstanding Alumni" award for his research and service. [8] In 2008, International Association for Food Protection (IAFP) recognized Beuchat's contributions to research by creating the annual Larry Beuchat Young Research Award. [2] In 2019 Beuchat received the Maurice Weber Laboratorian Award from IAFP. [2]
Salmonella is a genus of rod-shaped (bacillus) gram-negative bacteria of the family Enterobacteriaceae. The two known species of Salmonella are Salmonella enterica and Salmonella bongori. S. enterica is the type species and is further divided into six subspecies that include over 2,650 serotypes. Salmonella was named after Daniel Elmer Salmon (1850–1914), an American veterinary surgeon.
Salsa encompasses a variety of sauces used as condiments for tacos and other Mexican and Mexican-American foods, and as dips for tortilla chips. They may be raw or cooked, and are generally served at room temperature.
Listeria is a genus of bacteria that acts as an intracellular parasite in mammals. As of 2024, 28 species have been identified. The genus is named in honour of the British pioneer of sterile surgery Joseph Lister. Listeria species are Gram-positive, rod-shaped, and facultatively anaerobic, and do not produce endospores.
Plesiomonas shigelloides is a species of bacteria and the only member of its genus. It is a Gram-negative, rod-shaped bacterium which has been isolated from freshwater, freshwater fish, shellfish, cattle, goats, swine, cats, dogs, monkeys, vultures, snakes, toads and humans. It is considered a fecal coliform. P. shigelloides is a global distributed species, found globally outside of the polar ice caps.
Lebanon bologna is a type of cured, smoked, and fermented semidry beef sausage; it is not, in spite of its name, a pork-based bologna. Similar in appearance and texture to salami, it is somewhat darker in color, and is typically served as a cold cut or appetizer.
Penicillium roqueforti is a common saprotrophic fungus in the genus Penicillium. Widespread in nature, it can be isolated from soil, decaying organic matter, and plants.
Penicillium expansum is a psychrophilic blue mold that is common throughout the world in soil. It causes Blue Mold of apples, one of the most prevalent and economically damaging post-harvest diseases of apples.
Alicyclobacillus is a genus of Gram-variable, rod-shaped, spore-forming bacteria. The bacteria are able to grow in acidic conditions, while the spores are able to survive typical pasteurization procedures.
Michael Patrick Doyle is an microbiologist. He is an emeritus Regents Professor of Food Microbiology at the University of Georgia's College of Agricultural and Environmental Sciences and the former director of the college's Center for Food Safety, where he researched foodborne bacterial pathogens. Doyle was the first food microbiologist to study E. coli. He developed patents for several food safety interventions, including one used as a meat wash.
Food spoilage is the process where a food product becomes unsuitable to ingest by the consumer. The cause of such a process is due to many outside factors as a side-effect of the type of product it is, as well as how the product is packaged and stored. Due to food spoilage, one-third of the world's food produced for the consumption of humans is lost every year. Bacteria and various fungi are the cause of spoilage and can create serious consequences for the consumers, but there are preventive measures that can be taken.
Arcobacter skirrowii is a species of bacteria. It can be pathogenic.
Impedance microbiology is a microbiological technique used to measure the microbial number density of a sample by monitoring the electrical parameters of the growth medium. The ability of microbial metabolism to change the electrical conductivity of the growth medium was discovered by Stewart and further studied by other scientists such as Oker-Blom, Parson and Allison in the first half of 20th century. However, it was only in the late 1970s that, thanks to computer-controlled systems used to monitor impedance, the technique showed its full potential, as discussed in the works of Fistenberg-Eden & Eden, Ur & Brown and Cady.
Proteobiotics are natural metabolites which are produced by fermentation process of specific probiotic strains. These small oligopeptides were originally discovered in and isolated from culture media used to grow probiotic bacteria and may account for some of the health benefits of probiotics.
Case-ready meat, retail-ready meat, or pre-packaged meat refers to fresh meat that is processed and packaged at a central facility and delivered to the store ready to be put directly into the meat case.
Listeria innocua is a species of Gram-positive, rod-shaped bacteria. It is motile, facultatively anaerobic, and non-spore-forming. L. innocua was named innocua (innocuous) because, in contrast to Listeria monocytogenes, it does not readily cause disease in mammals. Another Listeria species, L. seeligeri, was named after one of the discoverers of L. innocua.
Millicent "Mimi" Edna Goldschmidt is an American microbiologist. Goldschmidt is known for her pioneering work in the field of astrobiology in addition to her medical research and her contributions to rapid testing methods for detecting microbial contaminants. Goldschmidt is a professor emerita at the University of Texas.
Lawrence Goodridge is the Leung Family Professor of Food Safety at the University of Guelph and Director of Guelph's Canadian Research Institute for Food Safety. Goodridge studies detection of and protection from food- and water-borne pathogens such as escherichia coli, salmonella and listeria. He uses wastewater testing to study the spread of COVID-19 and other diseases.
Edwin Michael Foster was an American microbiologist, specializing in food microbiology. He was the president of the American Society for Microbiology (ASM) in 1970.
Ann Marie McNamara is an American microbiologist and was formerly Vice President for Food Safety and Quality for the Supply Chain at US Foods. She has received a Distinguished Service Award from the United States Department of Agriculture, and received the International Association for Food Protection Fellow Award in 2012 and Food Safety Award in 2022.
