Those sealed glossy packs of cheeses and lunchmeat on your grocer's shelf can provide a particularly friendly home for nasty bugs that cause food poisoning, new research shows.

Vacuum-packed foods are deprived of oxygen to keep them fresh and boost their shelf life, but the same strategy is a boon for Listeria monocytogenes, a bacterium responsible for a kind of food poisoning that kills 25 percent of the people it infects.

Unlike many other food-borne germs, Listeria can grow even in the cold temperatures of refrigerators. The U.S. Food and Drug Administration notes that the microbe has been linked with foods such as raw milk; ice cream; soft-ripened cheeses such as feta, Brie and Camembert; hot dogs; raw and deli meats; raw vegetables; raw and cooked poultry; and raw and smoked fish.

In experiments with guinea pigs, Technical University of Denmark researchers found oxygen-deprived Listeria gets mean—up to 100 times more invasive than when grown with ample supplies of oxygen, findings which are detailed June 14 in the online journal BMC Microbiology.

The germ normally likes to live inside the oxygen-deprived gut, so it makes sense that it becomes more invasive under similar conditions, Licht said.

Avoiding vacuum packaging would lead to other problems with bacterial growth, so I'm not advocating that," food microbiologist Tine Licht told LiveScience. "But our work does help devise models predicting risk of food-borne disease."

Future research can determine genes key to the invasiveness of oxygen-deprived Listeria, Licht added. This in turn could help devise new methods to fight the germ.

Does SQ still serve vacuum packed food?? If lidat next time you take airplane please eat full full or bring snacks before you go onboard...

the best is to finish them once off, since less contact time with air = less time for bacteria to grow

wait... wait... does this mean that we are in a catch 22 situation... no matter what we do, we will always lose... vacuum packed, still has bacteria, no vacuum packed, even more bacteria... haiz

eat so many years also didnt die.
no big deal, serious -.-

AAAAAAAAAAAAAAAAAAA
