SUMMARY– Growth of freshly harvested mushrooms subjected to 100 krad of gamma irradiation is markedly inhibited, as measured by the small number of broken veils. This could significantly increase the storage life of mushrooms even under suboptimal conditions. Untreated mushrooms were preferred to the treated, but hedonic scores indicated that the treated mushrooms would be acceptable. There was no significant change in rate of moisture loss, or in reducing sugar or dry matter content of the irradiated mushrooms. Respiration of irradiated mushrooms is accelerated up to about 3 days after treatment and then slows markedly. The inclusion of 20% irradiated mushrooms in mouse diets fed in late pregnancy and lactation had no significant effects on the average mouse weight of the offspring 40 days old or on their daily food intake and weight gain in a subsequent 6‐wk feeding period.
