326. Fattened Geese, Preserving Fruit

46:29 In some places, non-Jews who raise geese pierce them under their wings so that the flesh will swell and the birds will appear fatter. In such a case, an authority must be consulted in order to determine whether or not the bird is kosher. Similarly, if an animal becomes ill from overeating, it might be pierced with an awl opposite one of its stomachs. An authority must also be consulted in cases such as this. 46:30 It was common, when preserving fruit, to seal the jar with an animal bladder. The jar was then heated in an oven. If this is done, one must make sure that the bladder is from a kosher animal, properly soaked and salted as required by halacha.
