caramel apples
After caramel-coated apples were linked to a listeriosis outbreak in 2014, Dr. Kathy Glass and the FRI Applied Food Safety Lab conducted a study that demonstrated the insertion of a stick into a caramel-coated apple accelerates the transfer of juice from the interior of the apple to its surface, creating a microenvironment at the apple-caramel interface where L. monocytogenes can rapidly grow to levels sufficient to cause disease when stored at room temperature.
2010

Stable, mutant strains of C. botulinum developed in which the botulinal neurotoxin gene has been inactivated.

Dr. Eric Johnson developed stable, mutant strains of C. botulinum in which the botulinal neurotoxin gene has been inactivated. These strains could be used for challenge studies to validate different food processing conditions and testing new food formulations.

Dr. Chuck Czuprynski became FRI director.

2008

CLA approved as a food ingredient.

On July 24, 2008, the FDA announced that conjugated linoleic acid is generally regarded as safe for use in foods. Read more
Dr. Michael Pariza discovered a number of health-promoting properties in CLA, including the ability to fight cancer and reduce heart disease. Along with animal sciences professor Dr. Mark Cook, Dr. Pariza found that CLA can help reduce body fat. Drs. Pariza and Cook have been awarded several patents on CLA technology, which are among the highest income-generating patents held by the Wisconsin Alumni Research Foundation.
2008

A key mechanism bridging mycotoxin biosynthesis and spore formation in molds was revealed.

Drs. Nancy Keller and Jae-Hyuk Yu, in collaboration with a German research group led by Dr. Gerhard Braus, revealed that certain light-responding velvet developmental regulators also govern biosynthesis of the aflatoxin-group mycotoxins in Aspergillus. This groundbreaking discovery was published in Science and opened a new research field. Read more
This important work was highly appraised by the research community and led fungal scientists to investigate the mechanisms further in other fungi. A tremendous amount of work in diverse fungi has uncovered that the velvet-mediated control of sporulation and mycotoxin biosynthesis is largely conserved in filamentous and dimorphic fungi.
2007

FRI moved into the new Microbial Sciences Building.

Microbial Sciences Building
As part of the Wisconsin BioStar Initiative, the Microbial Sciences Building was completed, and FRI joined MMI and Bacteriology faculty in the new building.






2007

2004

Dr. Kathy Glass expanded the FRI cheese spread safe processing strategy to include no-fat cheese spreads.

2001

Cold plasma engineering applied to food safety issues.

FRI scientist Dr. Ferencz Denes applied his pioneering work with plasmas to a variety of food safety issues. Dr. Denes obtained a patent through WARF that employs cold plasma technology to modify the surfaces of food-industry materials, such as processing machines, preparation surfaces, and packaging, to prevent bacterial attachment and biofilm formation. Read more
Techniques developed by Dr. Denes and Dr. Amy Wong, involved two steps. The first changed the surface of materials to incorporate anti-microbial agents in extremely thin layers. The second fused a protective film over the surface to make bacteria incapable of sticking and forming colonies.
2001

Sesquiterpenoids used to keep microbes vulnerable to antibacterial agents.

Dr. Eric Johnson and Dr. Byron Brehm-Stecher devised a way to keep microbes vulnerable to antibacterial agents by using sesquiterpenoids. Read more
When teamed with small amounts of sesquiterpenoids, antibiotics and other antibacterial agents became much better at killing bacteria, including some pathogenic strains. Sesquiterpenoids could also extend the life of antibiotics and antiseptics that might otherwise be vanquished by resistant microbes — a concern that keeps the pharmaceutical, food and sanitation industries constantly searching for new germ-killing agents.
2000

Food safety cluster hire expanded FRI expertise in mycotoxins, food safety engineering, and parasitology.

Dr. Jae-Hyuk Yu, Dr. Nancy Keller, Dr. Frank Denes, and Dr. Laura Knoll were brought on as part of FRI's food safety cluster hire. Drs.

1970

Sodium nitrite confirmed effective in preventing growth of C. botulinum in hot dogs.

In the early 1970s, Dr. Bob Deibel conducted a study to determine the effect of sodium nitrite, both alone and in combination with sodium ascorbate, on the growth of and toxin formation by Clostridium botulinum in inoculated, temperature-abused hot dogs. Read more
The results of this study confirmed that sodium nitrite was effective in preventing the growth of this pathogen in temperature-abused hot dogs. This information was used by the USDA to defend the continued use of sodium nitrite in cured meat products. Dr. Deibel also conducted important research into the problems with Staphylococcus aureus in fermented sausages.
1969

Food virology program was established by Dr. Dean Cliver in conjunction with the World Health Organization.

1969

Dr. Foster investigated Clostridium botulinum in Great Lakes fish.

Dr. Foster's research was in response to a 1963 outbreak of botulism in smoked Great Lakes fish that was vacuum-packed. Read more
At the time, vacuum packaging was a new technology for smoked fish, and people did not understand that C. botulinum was fairly common in fish, smoking did not kill the spores but did kill spoilage organisms, and if vacuum-packed smoked fish was not refrigerated carefully, spores could grow and produce toxin even if the fish still appeared safe. Dr. Foster's research demonstrated why the 1963 outbreak occurred.
1967

Enterotoxins isolated from Staphylococcus aureus.

Dr. Merlin Bergdoll isolated, identified, and purified enterotoxins A, B, C, and E from Staphylococcus aureus. This led to the development of tests to detect enterotoxins in food.
