The favorite starting p for skipper infestation is at the butl end of newly smoked ham- and shoulders. Here, when- the soft muscles and the connectiv< are exposed in cross section, are ideal feeding areas, 111 * - muscl< being somewhat separated, a condition which encourages penetra- tion by the maggots. In ham- entrance is effected frequently. Fig. 1.âC'ros section thrciu^h middle of a dry-cured ham badly Injured i>\ feeding of larvae of 1'iophibi tutaei. The uier layer of fat at the upper left lias collapsed o*ei the eaten-out cavities. Much reduced around the exposed bone on the inside, and less often at the hock end where the string passes through, in the small but deep holes hit by the inspector's trier, and in small cuts. In the usual well-advanced infestation the insects are found at the center of the meat, in the vicinity of the joint of the bones. In cured meat, putridity doe- not usually become marked until the infestation is rather old and consequently fouled by larval excreta. New colonies of the larva?, even though extensive, have little offensive odor, but the cavities of hams infested tor some time give off a strong moldy-sour odor similar to that of old brood comb. Miirtfeldt {53. p. 172) noted the lack of putrefaction in infested hams, but Sakharov {67) has given data to show that in infested fish the skipper maggots have a symbiotic relationship with an un- determined putrefactive Please note that these images are extracted from scanned page image
