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: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
