Litter observation- For F1 generation offspring were weighed individually on PNDs 0, 4, 7, 14, and 21 during the lactation period. The survival indices were calculated as (live offspring at each period)/ (live and dead offspring at birth) ×100%. Negative geotaxis, Cliff avoidance, Swimming behavior and olfactory orientation were observed on PND 4-14 .Food intake and chemical intake was observed during Preconception, mating, gestation and
Lactation.
For F2 generation offspring were weighed individually on PNDs 0, 4, 7, 14, and 21 during the lactation period. The survival indices were calculated as (live offspring at each period)/ (live and dead offspring at birth) ×100%. The offspring were weaned when they were 4 weeks of age, and one male and one female were selected at random from each litter to continue treatment. The animals were weighed individually at 4 weeks, 5 weeks, 6 weeks, 7 weeks, 8 weeks, and 9 weeks of age after weaning.
Animals at 7weeks of age in the F1 and F2 generation each performed 1 trial per day for 3 days in a Biel-type multiple-T water maze adapted for mice. Exploratory behavior of mice was measured in an animal movement analyzing system ANIMATE AT- at 8 weeks of in the F1 and F2. - Statistics:
- Food intake, litter size, litter weight, and body weight were assessed with Bonferroni’s multiple comparison tests after the analysis of variance (ANOVA) or the Kruskal–Wallis test. Sex ratio, survival and behavioural developmental data were assessed with the X2-test or with Fisher’s exact test of frequency analysis. Movement activity data were assessed with the Steel–Dwass test of non-parametric methods. Multiple-T water maze performance data were assessed with the Sign–Wilcoxon test for trials and assessed with the Steel–Dwass test within each treatment group. Dose-response effects were assessed with the Jonckheere test for ordered alternatives or the cumulative -test (multi) for frequency data.

Applicant's summary and conclusion
- Conclusions:
- NOAEL was found to be 642.8 mg/kg/day (0.45%) for Tartrazine in both F1and F 2generation (Crlj: CD1 male and female mice when their dams were exposed to test chemical by oral diet.
- Executive summary:
A three generation reproductive toxicity study was conducted for Tartrazine(1934-21-0) in (Crlj: CD1 male and female mice.The design of the study was based on the guidelines issued by ICH[12]and OECD[13]adapted for mice The test materialwas given to male and female mice in the diet at levels of 0 (control), 0.05%, 0.15%, and 0.45%(0, 71.3, 214.9 and 642.8 mg/kg/day)from 5 weeks of ageof the F0 generation to 9weeks of age of the F2 generation. 10 male and 10 female in each dose group.Clinical sign ,body weight, food consumption,chemical intake ,reproductive and neurobehavioral parameters were measured. Thelitter size or sex ratio at birth,litter weight and viability index of offspring were also observed..No. of females examined, No. of pregnant females, No. of litters No. of offspring, Average litter size, Average litter weight, Total sex ratio (male/female) and Average sex ratio (male %) were also observed.Exploratory behavior of mice was measured in an animal movement analyzing system ANIMATE AT- at 8 weeks of in the F0.
InParents,movement activity of exploratory behavior at 8 weeks of age, no variables of measurement showed a significant adverse effect of tartrazine in male and female mice of treated group compare to contol.No significant change was observed in themale and female mice during the preconception or mating periods in all treated group compare to control.Even the average body weight of dams showed no significant adverse effect during the gestation or lactation period in treated group compare to control.No significant change was observed in the food consumption ofmale and female mice during the preconception, mating periods, gestation and lactation period in all treated group compare 0,0.05%, 0.15%, and 0.45%to control.No significant change was observed in the chemical intake ofmale and female mice during the preconception, mating periods, gestation and lactation period in all treated group compare 0,0.05%, 0.15%, and 0.45%to control. Abortion was observed in four dams, one dam each in the lowdosed(0.05%) and middle-dosed groups(0.15), and two dams in the high-dosed groups (0.45%). One dam in the high-dosed group(0.45%)killed its all offspring during the first week of lactation. One dam in the control(0%) group had not nursed its offspring during the first week of lactation.
In the F1 generation,In the,0.05%dosed group, the average body weight of male and female offspring was increased significantly throughout the lactation period .In the0.15%dosed group, the average body weight of male offspring was increased significantly at PND 7.In the0.45%dosed group, the average body weight of male offspring was increased significantly at PND 21.No significant change was observed in themale and female mice during the preconception or mating periods in all treated group compare to control in F1 generation.
The averagebody weight of dams showed no significant adverse effect during the gestation or lactation period in all treated group0,0.05%, 0.15%, and 0.45% compare to control.No significant change was observed in the food consumption of F1male and female mice during the preconception ,mating periods, gestation and lactation period in all treated group compare 0,0.05%, 0.15%, and 0.45%to control.The development of swimming direction at postnatal day (PND) 7 was accelerated significantly in male offspring in a dose-related manner. Surface righting at PND 7 was affected significantly in female offspring in dose-related manner. Several variables in exploratory behavior showed significant tendencies to be affected in the treatment groups in male offspring at 3 weeksof age.
In the F2 generation, In the 0.05% dosed group, the average body weight of female offspring was affected significantly at birth and was increased significantly at PNDs 14 and 21, and that of male offspring was increased significantly at PNDs 7, 14 and 21. In 0.15% dosed group, the average body weight of male offspring was increased significantly throughout the lactation period, and that of female offspring was increased significantly at PNDs 7, 14 and 21. There was no sex-related difference in average body weight during the lactation period.No significant change was observed in the food consumption of F2male and female mice during the preconception, mating periods, gestation and lactation period in all treated group compare 0,0.05%, 0.15%, and 0.45%to control.No significant change was observed in the chemical intake of F2male and female mice during the preconception, mating periods, gestation and lactation period in all treated group 0,0.05%, 0.15%, and 0.45%compareto control.The development of swimming direction at PND 7was accelerated significantly in the 0.45%dosed group in male offspring. Time taken of olfactory orientation at PND 14 was accelerated significantly in male offspring in a dose-related manner. Several variables in exploratory behavior showed significant tendencies to be affected in the treatment groups in male offspring at 3 weeks of age, and in males at 8 weeks of age. The dose levels of tartrazine in the present study produced a few adverse effects on neurobehavioral parameters throughout generations in mice .But no adverse effect were observed on reproductive parameter in all generations of (Crlj: CD1 male and female mice in all treated group 0,0.05%, 0.15%, and 0.45% compareto control. Therefore NOAEL was considered to be 642.8 mg/kg/day (0.45%) for Tartrazine(1934-21-0) in both F1and F 2 generation (Crlj: CD1 male and female mice for developmental effect.
