light can increase danger of bacterial infections in foods

Certain bacteria in food can multiply significantly as to contaminate individuals if the food is exposed to light.

The bacterium actuates defensive mechanisms when exposed to light, scientists have now found this property particularly in Listeria; . This disclosure can, in future, be utilized by the food business to keep the spread of Listeria.

Listeria is a serious health hazard for pregnant women and for individuals with weak immune system. It is a bacterium found in food, which can contaminate individuals and cause immediate gastro-intestinal discomforts. The bacterium initiates defensive strategies when exposed to light and can cause deadly disease called listeriosis.

The bacterium, which once in a while causes the deadly disease listeriosis, responds to light by initiating safeguard systems according to the dissertation from Umeå College in Sweden.

Listeria bacterium can be risky for pregnant women and persons with weak immune system

The Listeria bacterium ordinarily causes no great damage separated from a couple of days of stomach issues for healthy people. The bacterium can be extremely hazardous in any case for people with a weak immune system or for pregnant women. Listeria can advance into “listeriosis” which has a death rate of 20-30 percent, in the event that the bacterial contamination spread to the brain. The microorganisms can spread to the baby and cause premature delivery on the off-chance that a pregnant woman is infected.

Named after the English specialist Joseph Lister, Listeria monocytogenes, is universal in nature yet can here and there spread to food, particularly to unpasteurized dairy items and charcuterie.

The Listeria bacterium can develop in food stored and can bring about contamination in the refrigerator, and if the infected food is consumed without being properly heated.

A new method found to fight treat the bacterium

A doctoral student at the Department of Molecular Biology at Umeå University, Christopher Anderson, in his paper, proposed how to combat the pathogenicity of the Listeria bacterium with two new atoms. The analysts additionally concentrated how the particles can be utilized to keep the bacterium from bringing about illness.

Christopher Anderson says, “Ideally, this new learning on how light and these little atoms influence the bacterium can, in future, be utilized to keep the spread of Listeria and treat listeriosis.”

To avoid contamination of food, eat them immediately after opening. Store the leftovers in refrigerator and away from direct source of light.
