| common-source outbreak of trichinosis associated with eating raw home-butchered pork. | four patients had trichinosis after consuming raw home-butchered pork. the patients had fever, myalgias, periorbital edema, and conjunctivitis. all of the patients had nausea, vomiting, or diarrhea (corresponding to the intestinal phase of the infection) seven to ten days before the onset of fever and myalgias. laboratory findings included eosinophilia, elevated serum cpk and aldolase values, and seroconversion of trichinella serology one month after onset of myalgias. the patients were treated ... | 1988 | 3043686 |
| drug residues in food animals. | a total of 292 field investigative reports of drug residues in food animals for 1983 to 1988 were analyzed. the investigations had been conducted by the food and drug administration (fda) and the virginia state veterinarian's office, in cooperation with the center for veterinary medicine of the fda, to trace residues reported by the usda food safety and inspection service to the source of the animal and the administration of the drug. the analysis disclosed the following. (1) antibiotic residues ... | 1989 | 2753793 |
| trichinosis: common source outbreak related to commercial pork. | fifteen patients had trichinosis after eating raw or undercooked commercial pork sausage produced by a local processing plant. even though it is recommended that all fresh pork be cooked to a temperature of at least 171 degrees f (77 degrees c) to ensure a sufficient margin of safety, this is not always done, and sporadic outbreaks continue to occur. control strategies to prevent human trichinosis should include trichinosis surveillance of all commercial swine, as well as strict compliance with ... | 1992 | 1566149 |
| an evolving pattern of human hydatid disease transmission in the united states. | echinococcus granulosus infection was being acquired in the contiguous united states by virginia sharecroppers and small-holders by the turn of the century. the last recorded human infection from that general area was diagnosed in 1947. by 1920 human infections were also being acquired in the lower mississippi valley. apparently, infection in both of these areas was maintained chiefly in swine. by 1940 a third transmission area definitely existed in the central valley of california, with its res ... | 1977 | 329700 |
| development of an nih consortium for preclinical assessment of cardioprotective therapies (caesar): a paradigm shift in studies of infarct size limitation. | an estimated 935 000 americans suffer a myocardial infarction every year; because their prognosis is determined by the size of the infarct, reducing infarct size is of paramount importance to alleviate morbidity and mortality. for 40 years, the national heart, lung, and blood institute (nhlbi) has invested enormous resources (at least several hundred million dollars) in preclinical studies aimed at developing infarct-sparing therapies, and several hundred (if not thousands) therapies have been c ... | 2011 | 21821536 |
