In an acute oral toxicity study (MRID [number]), groups (#/sex) of strain, species (source), (age, weight) were given a single oral dose of (formulation, note a.i. and %) in (name of vehicle or undiluted test article) at doses of , , or   mg/kg bw.  Animals were then observed for (#) days.


Oral LD50 Males =  mg/kg bw (95% C.I. if available)

      Females =  mg/kg bw (95% C.I. if available)

      Combined =  mg/kg  bw (95% C.I. if available)

      [or note if no mortality occurred, note if limit test]


Formulation is of (LOW, SLIGHT, MODERATE, HIGH) Toxicity based on the LD50 in (males or females which ever is lower, or lack of deaths at the limit dose)[include EPA Toxicity Category I, II, III, IV if joint review]. Label comment if applicable.


(Include only major treatment related clinical signs, body weight or necropsy signs including onset and/or duration if any or the following statement:  There were no treatment related clinical signs, necropsy findings or changes in body weight.)


This acute oral study is classified as [acceptable, unacceptable].  It does (not) satisfy the guideline requirement for an acute oral study (OPPTS 870.1100; OECD 401, 420, 423, 425) in the (species).  (If it does not satisfy the requirement, note if upgradable or not - if upgradable concisely list only major deficiencies or refer to deficiency section)
