Listeria Control in Consumer Protein Products

02.07.2008
Most cases of Listeria occur at the deli counter rather than at the manufacturer, yet most of the federal government’s sanitary guidelines are geared toward plants.

At this year’s Institute of Food Technologists Annual Conference and Food Expo, experts from the U.S. government, academia and food industry discussed how to minimize Listeria in facilities that process consumer protein products.

Some 80 percent of Listeria-related deaths occurred in people who bought sliced meat at a deli counter rather than packaged meat. But the primary regulators for retail establishments, such as delis and restaurants, are state-level inspectors. Much to the frustration of some retailers, the federal government has provided little guidance as to how to combat the dangerous pathogen.

“I can’t design a cleaning procedure until someone tells me what the rules are,” said O. Peter Snyder Jr., president of Hospitality Institute of Technology and Management. “If you think these things need to be washed, I’ll wash it, but tell me how to wash it.”

Snyder said the government has failed to provide retailers with specific standards they must achieve. So it is left to state inspectors, who conduct periodic inspections and either pass or fail the establishment based on their individual interpretations of cleanliness.

Most establishments have at least some presence of Listeria, whether it’s in a floor drain or on a meat slicer. Snyder said that it’s almost impossible to eradicate the facility entirely. Manufacturing plants are specifically designed to eliminate pathogens, but retail establishments are not, he said. Indeed, a 2006 study by New York’s Department of Agriculture found Listeria in 58 percent of the retail establishments they tested.

“I don’t know if it’s politics, but no one will come up with specific procedures,” Snyder said.

U.S. Department of Agriculture (USDA) officials say they are working to develop better data for the industry, but until then, retailers should decide for themselves how often and what methods to use to sanitize their facilities.

“Based on the data, they have found that about 80 percent of deaths related to deli meats are those packaged at the retail level,” said Janell Kause, director of the Office of Public Health Science, Food Safety and Inspection Service at the USDA. “If the problem is unsanitary conditions at processors, we need to figure out how we’re going to address that.”

One area of concern should be the deli’s drainage system. Most retailers don’t clean their drains properly, and part of the problem is that workers either don’t know better or simply won’t do better. Larry Kohl, a senior director of food safety programs at the Food Marketing Institute, said he once asked a chemical supplier to create a product that would essentially clean the drain itself. He asked for an alka-seltzer-type formula that would run down the drain, scrubbing along the way, using a tough ingredient that could break through the bacteria-laden biofilms and grease.

“Cleaning the drain is a nasty thing, that no one wants to do,” Kohl said.

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
