One hundred and twenty-five of 173 people who ate at a picnic and/or a smorgasbord prepared by a bar-restaurant in a Midwestern town in September 1973 developed diarrhea, abdominal cramps, and other symptoms 23 hours (median time) later. Eleven were hospitalized. Stool cultures from 18 ill individuals grew Salmonella infantis, Salmonella agona, and Salmonella schwarzengrund. Stool cultures from 5 of 8 restaurant employees grew S. infantis or S. agona. Cultures of remaining foods and food-contact surfaces were negative. Food-specific attack rates, based on interviews with 121 eaters, implicated potato salad and chicken dressing as vehicles of transmission, both likely contaminated when prepared in pans that shortly before contained uncooked, chicken pieces suspected to have harbored salmonellae. Chickens were eventually traced to 3 farms where feed samples were found to contain Salmonella typhimurium and Salmonella cubana, raising the possibility that other feed samples may have contained the serotypes responsible for the outbreak. The main control measure was temporarily closing the food service, which was to have catered a large church picnic the next day. The outbreak had an economic impact estimated at $28,733.
RESUMOO cascudinho (Alphitobius diaperinus) é um inseto considerado como uma das maiores pragas da indústria avícola no Brasil e em diversos países no mundo. A presença dele nos aviários gera diversos transtornos, pois sua ingestão pelas aves, prejudica o ganho de peso e também podem albergar e disseminar entre as aves diversos patógenos. Coletaram-se cascudinhos em seis empresas avícolas dos Estados do Rio Grande do Sul e Santa Catarina, constando de aviários de frangos de corte 54 amostras e de aviários de perus, 10 amostras. Através de métodos de bacteriologia convencional, foram isoladas 14 espécies de 10 gêneros de bactérias da família Enterobacteriaceae das superfícies externa e interna do cascudinho, sendo as quais: Cedecea sp. (6,89%), Citrobacter freundii (6,89%), Edwardsiella ictaluri (6,89%), Enterobacter aerogenes (5,07%), Enterobacter (Pantoea) agglomerans (0,37%), Enterobacter gergoviae (2,53%), Escherichia coli (36,96%), Klebsiella oxytoca (4,34%), Klebsiella pneumoniae (18,11%), Proteus mirabilis (8,34%), Proteus vulgaris (1,44%), Salmonella sp. (0,37%), Serratia marcescens (1,44%) e Yersinia enterocolitica (0,37%). A maior freqüência de isolados bacterianos e da diversidade de espécies isoladas foi observada na superfície externa do inseto quando comparado com a superfície interna. A presença destas enterobactérias nos cascudinhos demonstra que os mesmos são reservatórios potenciais de bactérias patogênicas para as aves.Descritores: cascudinho, enterobactérias, frangos de corte, perus, patologia aviária. ABSTRACTThe lesser mealworm (Alphitobius diaperinus) is an insect considered the great plague of the poultry raising in Brazil and many countries. The present of this insect in poultry farms produce several perturbations, its ingestion by poultry cause lower weight and to protect and to disseminate among poultry several pathogens. The lesser mealworm were harvested from six poultry farms in the states of Rio Grande do Sul and Santa Catarina. Fifty-four samples were harvested from broiler farms, whilst ten samples were harvested from turkey farms. Using the bacteriological analyze, was possible to isolate fourteen species from ten genus of bacteria from the Enterobacteriaceae family on the external and internal surfaces of the lesser mealworm: Cedecea sp. (6.89%), Citrobacter freundii (6.89%), Edwardsiella ictaluri (6.89%), Enterobacter aerogenes (5.07%), Enterobacter (Pantoea) agglomerans (0.37%), Enterobacter gergoviae (2.53%), Escherichia coli (36.96%), Klebsiella oxytoca (4.34%), Klebsiella pneumoniae (18.11%), Proteus miriabilis (8.34%), Proteus vulgaris (1.44%), Salmonella sp. (0.37%), Serratia marcescens (1.44%) and Yersinia enterocolitica (0.37%). The greater bacterial isolations frequency and the greater species diversity was observed in the external surface of the insect than in the internal surface. The presence of these bacteria on the lesser mealworm shows that it can work as a carrier of infectious agents for the poultry.
