If you are not familiar with food irradiation you will need to know that is developed in
early 1940 and is a radiation process meant to kill bacteria in food. This process in USA is being approved by FDA . Basically most food is irradiated like chicken , pork, beef , eggs , plants , spices, flours etc. Other countries and in special EU do not approve irradiation of foods for different reasons and one of it is that irradiation of food modify the genetics of foods and in test showed since early 1950 of irradiated food is of a fact showed that irradiated food increase the risks of cancers in lab rats. Another low point in irradiation is that of food is left after radiation with a metallic or unpleasant sulfurous taste.
As is true and undeniable that irradiation of food kills bacteria like E.coli , Salmonella , Trichinosis and other bacteria that cause food born viruses, irradiation modify the cell structure of food as well .
Irradiation of food is not 100% safe as studies showed that bacteria found in fecal matter like E.coli are present even after the irradiation processed is completed and food is still infected.
Irradiation is used in large productivity of foods but recently large amounts of ground beef has been recalled from USA market and probably that irradiation process wasn’t safe enough or we may need to adhere to higher standers of food safety.
