CRITICAL NOTICE

First aid buys time for professional treatment. It is not a substitute for veterinary care.

---

STEP 1: STOP THE EXPOSURE

  • Move to safe, clean area
  • If source is in pasture—move ALL animals out
  • Remove source from animals
  • Take away contaminated feed
  • Block access to toxic plants
  • Secure chemical containers
  • Prevent additional animals from exposure
  • Close gates
  • Post warning
  • Notify others on property
---

STEP 2: ASSESS THE SITUATION

Rapid Assessment Checklist

  • [ ] Approximately how much?
  • [ ] When did exposure occur?
  • [ ] How many animals affected?
  • [ ] Current symptoms?
  • [ ] Severity level?

Severity Levels

LevelSignsUrgency
CRITICALSeizures, collapse, severe respiratory distress, no pulseImmediate - may not survive transport
SEVEREDown, extreme weakness, bloody discharge, severe symptomsEmergency - vet ASAP
MODERATEStanding but symptomatic, weakness, GI signsUrgent - vet within hours
MILDMinor symptoms, eating/drinking, alertSame-day vet consultation

STEP 3: CALL FOR HELP

Emergency Contacts

  • Phone: _______________
  • Emergency: _______________
  • ASPCA Animal Poison Control

Information to Provide

  • Species, age, weight of affected animals
  • Number of animals affected

STEP 4: SPECIFIC FIRST AID BY TOXIN TYPE

A. PLANT POISONING (General)

  • Provide clean water
  • Keep animal calm and quiet
  • Collect plant sample for identification
  • Monitor vital signs
  • Stress the animal unnecessarily
  • Attempt to induce vomiting (cattle rarely can)
  • Give medications without vet guidance

B. CYANIDE (Prussic Acid) - Sorghum, Cherry, etc.

  • Sudden onset
  • Bright red blood
  • Rapid/difficult breathing
  • Staggering → collapse
  • Cherry red mucous membranes
  • Keep animal calm (stress accelerates death)
  • Call vet - specific antidote available
  • If vet provides sodium thiosulfate/nitrite - follow directions exactly
  • Without antidote, mortality very high
  • Every minute counts

C. NITRATE POISONING

  • Rapid breathing
  • Weakness
  • Staggering
  • Blue/brown mucous membranes
  • Keep calm
  • Call vet immediately
  • Antidote: Methylene blue IV (vet administered)

D. UREA/NPN TOXICITY

  • Bloating (rapid onset)
  • Muscle tremors
  • Frothing at mouth
  • Incoordination
  • Violent struggling → collapse
  • 1-2 quarts (liters) white vinegar
  • Give orally via stomach tube or drench bottle
  • Can repeat in 15-30 minutes
  • Cold water drench
  • 5-10 gallons cold water
  • Dilutes rumen contents
  • If severely bloated:
  • Emergency trocarization may be needed
  • Vet should perform if possible

E. ANTICOAGULANT RODENTICIDE

  • Bloody nose, urine, feces
  • Weakness, pale gums
  • Swelling/hematomas
  • Sudden death
  • Antidote: Vitamin K1 (phytonadione)
  • Give Vitamin K1 if available: 1-2 mg/kg
  • Treatment may be needed for weeks
  • Do NOT use vitamin K3

F. OLEANDER / CARDIAC GLYCOSIDES

  • Sudden death possible
  • Irregular heartbeat
  • Drooling, vomiting attempts
  • Weakness, collapse
  • Diarrhea
  • Keep calm and quiet
  • Activated charcoal if recent ingestion
  • Cardiac monitoring essential
  • Specific antidotes available (Digibind) - vet must administer

G. ORGANOPHOSPHATE / CARBAMATE POISONING

  • Pinpoint pupils
  • Muscle twitching
  • Difficulty breathing
  • Seizures
  • Remove contaminated material from skin (careful - handler exposure risk)
  • Antidote: Atropine (vet administered)
  • 2-PAM may be given (vet)

H. COPPER TOXICITY (Hemolytic Crisis)

  • Dark red-brown urine
  • Jaundice (yellow)
  • Rapid breathing
  • Collapse
  • Supportive care only
  • IV fluids if available
  • Prognosis poor once crisis occurs

I. OAK POISONING

  • Constipation → bloody diarrhea
  • Frequent urination
  • Swelling (edema)
  • Provide calcium supplementation (calcium hydroxide drench)
  • Fresh water
  • Supportive care
  • Kidney damage may be irreversible
---

STEP 5: SUPPORTIVE CARE WHILE WAITING FOR VET

General Supportive Measures

  • [ ] Provide bedding if down
  • [ ] Protect from weather extremes
  • [ ] Keep other animals away
  • [ ] Check heart rate if possible
  • [ ] Monitor for worsening symptoms
  • [ ] Note any changes for vet
  • [ ] Small amounts of clean hay (if eating)
  • Drench animals that can't swallow
  • Give random medications
  • Delay calling veterinarian

If Animal is Down

  • If lateral (on side), switch sides every few hours
  • Keep head elevated if breathing difficulty
  • Pad pressure points if extended time down
  • Respiratory changes
  • Circulation to limbs

STEP 6: SAMPLE COLLECTION

Samples to Collect

|--------|-----------|---------| | Suspected plant | Paper bag (not plastic) | Refrigerate | | Feed/hay | Paper bag | Dry, labeled | | Water | Clean jar | Refrigerate | | Vomitus (if any) | Plastic container | Refrigerate | | Feces | Plastic bag | Refrigerate | | Blood | Vet collects | Follow vet instructions |

  • Keep carcass cool until necropsy
  • Note: Some toxins degrade rapidly

Sample Labeling

  • Location collected
  • Animal ID if applicable
  • Your name and contact
  • Suspected toxin (if known)
---

STEP 7: DOCUMENTATION

Record Immediately

|-------|-------------| | Date/time discovered | | | Date/time exposure estimated | | | Suspected source | | | Animals affected (ID numbers) | | | Initial symptoms | | | Actions taken | | | Time vet called | | | Treatment given | | | Outcome | |

Photography

  • Suspected toxin source
  • Plant specimens
  • Feed/water source
  • Any visible physical evidence
