| assessment of the hazards of polybrominated biphenyls. | during their peak use period, pbbs represented under 1% of the total sales of fire retardant chemicals, and very probably would have escaped intensive study if they had not been mixed accidentally with animal feed preparations. instead, international attention was drawn to pbbs by the state-supervised killing of over 35,000 cattle which had been contaminated with pbbs. interestingly, low doses of pbbs exert a broad spectrum of toxicological, pharmacological, and biochemical effects despite low a ... | 1978 | 209999 |
| health problems in veterinary students after visiting a commercial swine farm. | in october 1993 and 1994, respectively, 77 and 76 third-year veterinary students visited a swine farm to work with pigs for 3 h. on both occasions, a large number of students reported flu-like symptoms after the visit. to further investigate this, the students were presented with a questionnaire modeled after the standard questionnaire used for evaluating organic dust exposure. general and/or respiratory symptoms were reported by 103/142 (72.5%) students. general symptoms, such as eye irritation ... | 1998 | 9442939 |
| wisconsin's "stale calf" issue and a study designed to resolve some of the animal welfare concerns. | a unique law (act 201) requiring livestock markets to place an identifying mark on calves up to 90 kg each time they are sold went into effect in wisconsin in 1993. the intent of the law is to reduce the number of times calves are resold and hence become "stale." the original proponents of the law proposed that calves be ear-notched each time they are sold. ear notching, however, was resisted by wisconsin regulatory agencies partly because of fear of an adverse public reaction. these authors the ... | 1994 | 8002445 |
| airborne contaminants and farmers health in swine farms with high and low prevalence of respiratory diseases in pigs. | the main purpose of this study was to investigate the relationship between prevalence of respiratory disease in swine and respiratory health of swine farmers. fourteen farms were selected based on clinical history and slaughtercheck evidence of respiratory problems in pigs. the farms were divided into two groups with either high (n = 7) or low (n = 7) prevalence of respiratory disease in pigs. airborne dust, endotoxin and peptidoglycan were measured once in farrowing, gestation, nursery and fini ... | 1998 | 9852495 |
