SAY NO TO IRRADIATED FOODS – REQUIRE LABELING! By Neil E. Levin, CCN, DANLA I do not want to eat irradiated foods. I should be able to obtain information on how my food is produced and processed so that I can make educated dietary choices, as is my right. But the FDA wants to allow irradiated foods to be labeled as “pasteurized”, without requiring them to bear the irradiation symbol (the radura logo). That would eliminate my ability to ‘vote with my pocketbook’ by making informed choices. If there is a demonstrated benefit to eating irradiated foods that outweighs the known and suspected risks, let the manufacturers sell us on the safety and benefit of their products, using the free market. If they can convince us that there are benefits, then the irradiation symbol will be a positive in the marketplace. If not, if may be a negative. But that’s up to them to make their best case. At least that would be true in a free market, if we were told which foods are irradiated and why. By allowing manufacturers to hide their questionable practices (whether irradiation, chemicals or genetic engineering) the FDA is artificially subsidizing businesses at the expense of consumers’ freedom of choice. That is not free market economics and eliminates any possibility of consumers being able to make their own decisions. We deserve more respect. Moreover, there are known, detectable changes to foods treated with radiation, making them measurably different from all other foods (see the quotes and references below). This proves that the FDA’s proposal of labeling them as merely “pasteurized” is actually misleading. Send your comments to the FDA to insist that irradiated foods be labeled, since they are clearly different from other foods. You can do this at: REFERENCES: “The 2-alkylcyclobutanones (2-ACBs) are formed from triglycerides by irradiation treatment and may be used as markers for this type of food processing.” (Horvatovich P, et al. Determination of monounsaturated alkyl side chain 2-alkylcyclobutanones in irradiated foods. J Agric Food Chem. 2005 Jul 27;53(15):5836-41. PMID: 16028962) “Both the free radicals and the alkylcyclobutanones were found to increase with irradiation dose. In general, linear relationships between the amount of radicals and irradiation dosage could be established.” (Sin DW, Wong YC, Yao WY. Analysis of gamma-irradiated melon, pumpkin, and sunflower seeds by electron paramagnetic resonance spectroscopy and gas chromatography-mass spectrometry. J Agric Food Chem. 2006 Sep 20;54(19):7159-66. PMID: 16968077) “The irradiation of fat results in the formation of 2-alkylcyclobutanones, a new class of food contaminants. Results of previous in vitro studies with primary human colon cells and in vivo experiments with rats fed with 2-alkylcyclobutanones indicated that these radiolytic derivatives may be genotoxic and enhance the progression of colon tumors…In summary, 2dDCB [2-dodecylcyclobutanone] was clearly genotoxic in healthy human colon epithelial cells and in cells representing preneoplastic colon adenoma. These findings provide additional evidence that this compound may be regarded as a possible risk factor for processes in colon carcinogenesis related to initiation and progression.” (Knoll N, et al. 2-Dodecylcyclobutanone, a radiolytic product of palmitic acid, is genotoxic in primary human colon cells and in cells from preneoplastic lesions.

PMID: 16153665) “Alkylcyclobutanones (2-ACBs) are suspected cancer promoters and clastogens, which have raised concerns about the safety of irradiated foods.” (Gadgil P, Smith JS.

PMID: 16787045) “This is the first demonstration that a compound found exclusively in irradiated dietary fats may promote colon carcinogenesis in animals treated with a chemical carcinogen.” (Raul F, et al. Food-borne radiolytic compounds (2-alkylcyclobutanones) may promote experimental colon carcinogenesis. Nutr Cancer. 2002;44(2):189-91. PMID: 12734067)
