title: Detection of steroid hormone (estrogen) residues in imported red meat.
abstract: 28 immature female albino mice were utilized to clarify if there was a sufficient amount of the hormonal agent used in the production of meat for human consumption, such as estrogen, can remain in meat cut from carcasses of animals administered hormones during finishing to have deletorious effects on human ingestors. The animals were divided into 4 equal groups, group A: control, fed on normal ration, group B: each mouse were injected with 0.2 microgram of estradiol propionate i. p. daily, group C: were fed on normal ration mixed with imported minced meat, 5 g/mouse/day, group D: were fed as in group C, but we used local minced meat. Sera were collected after one week. There were significant increase in both FSH and LH in group B, slight rise in both FSH and LH in groups C and D but group A have the lower level of both FSH and LH. The number of Graafian follicle were significantly higher in group B, also the body weight of group B, were rapidly increased more than other groups. Both of groups C and D nearly inclose to each other, in body weight, indicating that imported meat were free from any estrogenic residues in comparison to our local meat.
