Pig Swine Dysentery Welfare Impact

Swine dysentery is a devastating enteric disease causing hemorrhagic diarrhea and significant suffering in affected pigs.

Key Facts

Swine dysentery is caused by Brachyspira hyodysenteriae in the large intestine
Characteristic bloody, mucoid diarrhea causes fluid loss, pain, and anemia
Mortality without treatment can reach 30 to 50 percent in severe outbreaks
The disease is endemic in many countries and difficult to eradicate once established
Biosecurity failures including contaminated vehicles and equipment spread infection between farms

Welfare Considerations

Pigs with swine dysentery experience severe abdominal pain, hemorrhagic diarrhea, and systemic illness. The disease causes profound suffering and requires urgent veterinary treatment.

What You Can Do

Support farms with rigorous biosecurity programs to prevent dysentery introduction
Advocate for antibiotic stewardship frameworks that maintain treatment efficacy for severe disease
Choose pork from farms with documented enteric disease monitoring and management
