Migrated information
Conclusions:
LD50 exceeding the limit dose of 2000 mg/kg bw
Executive summary:

In an acute oral toxicity study according to OECD guideline 423 a group of female CD rats received a limit dose of 2000 mg/kd bw of FeNaEDTA by gavage administration. No adverse effects were noted, no clinical signs, no mortalities, no effect on body weight and no adverse findings at final necropsy after a 14 days observation period. The LD50 (oral,rat) exceeded 2000 mg/kg bw.
