FAT 20297/C was weighed on a calibrated Mettler balance. The pulverised diet was then homogeneously mixed with the appropriate concentrations of the compound and about 25% water was added before pelleting to ensure the necessary pellet quality. The pellets were subsequently airdried. The animals in the control group (group 1) were fed with similarly pelleted feed without the test substance..PREPARATION OF DOSING SOLUTIONS: - Analytical verification of doses or concentrations:

OTHER: Hearing test: Animals of the highest dosage group and of the control group were examined before (day -6) and towards the end (day 27) of the treatment period. - Sacrifice and pathology:
- At the end of the test period all control and test animals which survived were bled under ether anaesthesia and subjected to detailed autopsy.
Besides the weight of the exsanguinated body the organs weights were also recorded.
After the fixation organ samples from each control and test rat were taken, embedded in paraplast, sectionned at 3-5 micron, stained with haematoxylin and eosin and subjected to microscopic examination. - Statistics:
- For each time point and parameter a uni-variate statistical analysis was conducted. Due to the routine manner of the analysis system, parameter free methods were applied. Each treated group was compared to the control group in respect of dispersion and displacement. In addition a trend test was applied considering all groups.
Statistical analysis is performed to draw attention to distinct values. A statistically significant difference between two values does not necessarily imply biological relevance of that deviation and is not conclusive for a treatment related effect.
Hence, the responsible scientist may not comment on statistically significant values lying within the physiological range and on the other hand may comment on statistically not significant values, which differ substantially from the expected normal values.
Results and discussion
Results of examinations
- Clinical signs:
- no effects observed
- Description (incidence and severity):
- No clinical symptoms and no signs of local and/or systemic toxicity were observed.
- Mortality:
- no mortality observed
- Description (incidence):
- No death occurred during the course of the study.
- Body weight and weight changes:
- no effects observed
- Description (incidence and severity):
- The mean body weight of all treated male and female groups was similar to that of the respective controls.
- Food consumption and compound intake (if feeding study):
- no effects observed
- Description (incidence and severity):
- The mean food consumption was slightly higher in both treated male and female animals of group 4 (10000 ppm) compared to the respective control. The mean food consumption of the other treated male and female groups was similar to that of the respective control groups.
- Food efficiency:
- no effects observed
- Description (incidence and severity):
- The mean food conversion of female group 4 (10000 ppm) was higher than the respective control ratio, thus indicating spillage of food due to reduced palatability of the medicated diet.
Specific food consumption in relation to body weight - addressed as food conversion ratio - of the other treated animals was similar to the control ratios. - Water consumption and compound intake (if drinking water study):
- effects observed, non-treatment-related
- Description (incidence and severity):
- The mean water consumption showed a tendency to increased intake in both treated male and female groups 3 and 4 (3000 and 10000 ppm). However, since water consumption was measured only by cage, the number of values (n = 2) does not allow for a definite judgement about the relevance of this finding. The toxicological significance of this deflection is however in doubt.
The mean water consumption of treated male and female group 2 (1000 ppm) was similar to that of the respective control groups (the low value of the female control at week 4 is considered unreliable). - Ophthalmological findings:
- no effects observed
- Description (incidence and severity):
- Ophthalmic inspections and hearing examinations performed before (day -6) and towards the end (day 27) of the application period revealed no evidence of a reaction to the treatment.
- Haematological findings:
- no effects observed
- Description (incidence and severity):
- No difference, which could be related to the test compound was found between treated and control animals in the hematological values.
- Clinical biochemistry findings:
- no effects observed
- Description (incidence and severity):
- Throughout the treated groups, no changes were observed, which could be related to the substance administration.
- Urinalysis findings:
- not examined
- Behaviour (functional findings):
- not examined
- Immunological findings:
- not examined
- Organ weight findings including organ / body weight ratios:
- effects observed, treatment-related
- Description (incidence and severity):
- Absolute and relative mean liver weight of both treated male and female groups 4 (10000 ppm) were significantly depressed. Additional statistically significant differences in organ weights, attributed to spontaneous variation rather than to the treatment were also observed.
- Gross pathological findings:
- effects observed, non-treatment-related
- Description (incidence and severity):
- No treatment related gross pathological findings were observed. All other gross and histopathological lesions seen in some control and test animals were only incidental in nature and not due to the application of the tested compound.
- Neuropathological findings:
- not examined
- Histopathological findings: non-neoplastic:
- effects observed, treatment-related
- Description (incidence and severity):
- Microscopical examination revealed slightly more pronounced fatty changes of the hepatocytes in female and male animals of group 4 (10000 ppm).
- Histopathological findings: neoplastic:
- no effects observed

Dosage Levels: The amount of test material in the diet was determined analytically during the study. The results of these analyses revealed a concentration of 96.6 - 104.6% of the nominal value.
According to the analytical results the calculated mean daily intake of FAT 20297/C was approximately 104, 297 and 1050 mg/kg bw. in males and 102, 282 and 1090 mg/kg bw in females.
Applicant's summary and conclusion
- Conclusions:
- "No observed effect level" for FAT 20297/C when offiered to rats continuously in their feed over a period of 28 days is 3000 ppm, corresponding to a mean daily intake of FAT 20297/C of 297 mg/kg body weight for males and 282 mg/kg bw for females.
- Executive summary:
The repeated dose toxicity of Acid Blue 344 was investigated in this study conducted according to OECD Guideline 407. In this study a total of 80 RAIf (SPF) rats, 10 males and 10 females per dose group were used. The test article FAT 20297/C was administered in the diet for 28 days at dosages of 1000, 3000 and 10000 ppm ( = mg/kg feed). According to the analytical results the calculated mean daily intake of FAT 20297/C was approximately 104, 297 and 1050 mg/kg bw in males and 102, 282 and 1090 mg/kg bw in females. After 28 days of daily dose administration, no mortality or clinical symptoms/ systemic toxicity were observed at any dose levels. No treatment related effect on body weights, food and water consumption, food conversion, eyes, hearing capability, hematology and blood chemistry was observed. However, absolute and relative mean liver weights of both treated male and female groups 4 (10000 ppm) were significantly depressed. Microscopical examination revealed slightly more pronounced fatty changes of the hepatocytes in female and male animals of group 4 (10000 ppm). Based on these findings, "No observed effect level" for FAT 20297/C is 3000 ppm, corresponding to a mean daily intake of 297 mg/kg bw for males and 282 mg/kg bw for females.
