Section 3: Hazards Identification
Symptoms of Acute Exposure
Ingestion: This product consists of dried, ground Pyrethrum flowers, of the family chrysanthemum
cineraraefolium. While it is extremely unlikely that any individual may ingest sufficient quantities of
this powder to cause illness, symptoms of ingestion may include gastrointestinal effects, such as nausea,
cramps, vomiting and diarrhea, nervous system effects, such as dizziness, loss of coordination, tremors,
and loss of consciousness. Symptoms usually regress with no long lasting effects.
Eyes: May cause temporary eye irritation.
Skin: May be irritating to skin. Because this product is dried, finely ground powder of a flower,
repeated contact may cause dermatitis or other allergenic effects.
Inhalation: Because this product is dried, finely ground powder of a flower, inhalation may cause nasal
and respiratory irritation or other allergenic reactions such as hay fever symptoms.
Medical Conditions Generally Aggravated by Exposure: May cause allergic effects such as hay
fever.

Section 4: First Aid Measures
Ingestion: Call a physician or Poison Control Center immediately.
Inhalation: Remove victim to fresh air. Administer artificial respiration if necessary.

Section 10: Stability and Reactivity
Reactivity:
Stability Stable.
Hazardous Polymerization: Will not occur.
Conditions to avoid: None known.
Hazardous Decomposition Products: None known.

Section 11: Toxicological Information
Acute toxicity/irritation studies:
Pyrethrins (58% manufacturing grade liquid):
Ingestion: Slightly toxic
Oral LD50 (Rat) 2,370 mg/kg (58% pyrethrins)
Dermal: Slightly toxic
Dermal LD50 (Rabbit) >2,000 mg/kg (58% pyrethrins)
Inhalation: Slightly toxic
Inhalation LC50 3.4 mg/L (58% pyrethrins)
Eye Contact: Minimally irritating (Rabbit)
Skin Contact: Minimally irritating (Rabbit)
Skin Sensitization: Not a sensitizer (Guinea Pig)
Mutagenic Potential: Pyrethrins 鈥? none observed.
Reproductive Hazard Potential: Pyrethrins 鈥? none observed.
Chronic/Subchronic Toxicity: Pyrethrins 鈥? none observed.
Carcinogenicity/Oncogenicity - Carcinogenicity/Oncogenicity 鈥? Pyrethrum has been tested in chronic
feeding studies in mice and rats. Slightly elevated incidences of benign tumors of the thyroid and liver
were seen in rats following high doses of Pyrethrum. Further detailed scientific studies into the
mechanism causing these responses indicate that these effects in animals only occur at doses greatly
exceeding the likely human exposure levels. Thus, the effects seen in animals are of little relevance to
humans.
Other toxicity information: Not available.
Target Organs: Central nervous system.
