- Conclusions:

- Executive summary:
In accordance with OECD guideline 423 (2001) and according to GLP principles the acute oral toxicity of the substance in rats was investigated. MMF was administered by oral gavage to two subsequent groups of three female Wistar rats at 2000 mg/kg body weight. Animals were subjected to daily observations and weekly determination of body weight. Macroscopic examination was performed after terminal sacrifice (Day 15). No mortality occurred. A combination of lethargy, hunched posture, uncoordinated movements, slow breathing, piloerection, watery discharge from the eyes, chromodacryorrhoea (snout) and/or ptosis was noted for all animals. The first set of animals had recovered from all symptoms on Day 5 and the second set of animals had recovered from all symptoms between Days 2 and 3. Two animals of the first set showed slight body weight loss or reduced body weight gain over the first week post-treatment. The mean body weight gain shown by the other animals over the study period was considered to be similar to that expected of normal untreated animals of the same age and strain. No abnormalities were found at macroscopic post mortem examination of the animals. The oral LD50 value of MMF in Wistar rats was established to exceed 2000 mg/kg body weight. Based on the results of this study, the substance does not need to be classified for acute oral toxicity in accordance with Regulation (EC) No 1272/2008.
