Prevention of poultry-borne salmonellosis by irradiation: costs and benefits in Scotland.

Poultry-borne salmonellosis is the most common foodborne infection in Scotland for which the vehicle can be identified. The cost of the disease to society in terms of health service use, absence from work, morbidity, and mortality is substantial. The study estimates the total cost of poultry-borne salmonellosis in Scotland and compares it with the cost of a single preventive measure: the irradiation of poultry meat. The results suggest that the public health benefits exceed irradiation costs. This conclusion is, however, sensitive to assumptions made in the analysis, particularly those related to the cost of unreported cases of salmonellosis.

Physiological activity of irradiated green tea polyphenol on the human skin.

Physiological activity of irradiated green tea polyphenol on the human skin was investigated for further industrial application. The green tea polyphenol was separated and irradiated at 40 kGy by y-ray. For an anti-wrinkle effect, the collagenase inhibition effect was higher in the irradiated sample (65.3%) than that of the non-irradiated control (56.8%) at 200 ppm of the concentration (p < 0.05). Collagen biosynthesis rates using a human fibroblast were 19.4% and 16.3% in the irradiated and the non-irradiated polyphenols, respectively. The tyrosinase inhibition effect, which is related to the skin-whitening effect, showed a 45.2% and 42.9% in the irradiated and the non-irradiated polyphenols, respectively, at a 100 ppm level. A higher than 90% growth inhibition on skin cancer cells (SK-MEL-2 and G361) was demonstrated in both the irradiated and the non-irradiated polyphenols. Thus, the irradiation of green tea polyphenol did not change and even increased its anti-wrinkle, skin-whitening and anticancer effects on the human skin. The results indicated that irradiated green tea polyphenol can be used as a natural ingredient with excellent physiological functions for the human skin through cosmetic or food composition.

ESR analysis of irradiated frogs' legs and fishes.

Electron spin resonance (ESR) spectral analysis of different parts (bones, scales, jaw, etc.) from ionized (irradiated) frozen frogs' legs and fishes (brown trout and sardine) were recorded. There is always present, after treatment, a signal due to the irradiation. ESR and ENDOR experiments lead us to assign it to h1 centers from hydroxyapatite, as in the case of other irradiated meat bones. The use of ESR to prove whether one of these foods has been irradiated or not is discussed.
