Administration / exposure

Route of administration:
oral: feed
Type of inhalation exposure (if applicable):
not specified
Vehicle:

Details on mating procedure:
No data
Analytical verification of doses or concentrations:
not specified
Duration of treatment / exposure:
2 weeks before the first mating and dosing continued throughout the gestation, lactation, and post-weaning phases for three successive generations.
Frequency of treatment:
Daily
Details on study schedule:
The F0 generation rats were mated twice. The F0 generation rats were mated twice, the F1a litters being necropsied and F1b litters were used for breeding. Animals from the F1b generation were mated 3 times and the offspring of the F2a and F2b generations were treated identically to the F1a and F1b generations.In third mating half of the pregnant dams were sacrificed on day 19 of gestation and other half were allowed to deliver normally (F2c) and sacrificed at weaning. The F2b animals were mated once and allowed to raise their offspring to weaning.

Examinations

Parental animals: Observations and examinations:
Parental animals observation and examinationsCAGE SIDE OBSERVATIONS: Yes - Time schedule: No data available- Cage side observations checked in table [No.?] were included.: Observations were also done to record any adult mortality.
Litter observations:
Survival, weights and sex were observed
Postmortem examinations (parental animals):
Postmortem examinations (Parent Animal)SACRIFICEThe F1a and F2c litters being necropsied at weaning.F1a and F1b, Following the third mating, half of the pregnant dams were sacrificed on day 19 of gestation.The F2b animals were mated once and allowed to raise their offspring to weaning when both parents and offspring were culled.GROSS NECROPSY- Gross necropsies were performed on F1a, F2a, and F2c
Postmortem examinations (offspring):
SACRIFICEF3a generation at weaning was fixed at necropsy.GROSS NECROPSY- Gross necropsies were performed on F3a offspring at weaning. HISTOPATHOLOGY were performed on all parent animals. Selected tissues from 5 animals of each sex/dose from the F1b parents were fixed at necropsy and tissues examined histologically from the control group and high-dose group.Organ examined: Stomach, ileum, jejunum, colon, liver, spleen, heart, lungs, adrenals, kidneys, urinary bladder, thyroid, ovaries, and uterus or testes were examined. Total embryos/resorption sites, and the corpora lutea per ovary were recorded
Reproductive indices:
Mating performance, pregnancy and fertility rates, gestation length and resorption rates were examined.
Offspring viability indices:
Yes

Applicant's summary and conclusion

Conclusions:
NOAEL was considered to be 1000 mg/kg body weight /day when Long-Evans male and female rat treated with Fast Green FCF.
Executive summary:

In a 3-generation reproductive toxicity study,Long-Evans male and female rat treated with Fast Green FCF in the concentration of 0, 10, 100, 300 and 1,000 mg/kg b.w. /day orally in diet. No effect were observed onsurvival, food consumption and body weight of F1, F2 and F3 generation treated male and female rat. Similarly, no effect were observed on mating performance, pregnancy and fertility rates, gestation length, offspring survival, weights and sex, litter survival and resorption rates of F1, F2 and F3 generation treated male and female rat. In addition,No gross pathological changes and macroscopic or microscopic tissue abnormalitieswere observed inF1, F2 and F3 generation treated male and female rat.

Therefore,NOAEL was considered to be1000 mg/kg body weight /daywhen Long-Evans male and female rat treated with Fast Green FCF orally in diet.
