Abstract:

Sunset Yellow FCF was tested for 28-days in male Hsd:SD® rats for its potential effect on sperm quality parameters at dietary concentrations of 6,000, 12,000 and 18,000 ppm, corresponding to target doses of 500, 1000, and 1500 mg/kg bw/day. The measured average daily intake was 490, 944, and 1,475 mg/kg bw/day, based on feed consumption and stability of Sunset Yellow FCF in the diet. The animals fed diets with Sunset Yellow FCF presented no clinical signs of toxicity and no differences in feed consumption, body weights, organ weights, ophthalmology, hematology, clinical chemistry, urinalysis, or coagulation parameters that were considered adverse. No mortality or abnormalities were observed at necropsy, and no microscopic changes were observed in histopathology. Increased testes weights relative to body weight in animals of the middle and high intake groups were not associated with any abnormal findings in histopathology. Sperm quality evaluation presented no adverse effects on sperm motility, epididymal sperm count, homogenization-resistant spermatid count, or sperm morphological development. Therefore, in the absence of any adverse effects under the conditions of this study, the NOAEL for Sunset Yellow FCF was 1,475 mg/kg bw/day in male rats, corresponding to 18,000 ppm in the diet.
