The UK pig sector has quietly delivered one of the most significant veterinary public health achievements of the last decade, cutting antibiotic usage by 72 per cent. Newly released figures show that in 2025, usage fell once again to 77.2 mg/PCU, cementing the industry's position as a leader in responsible medicine stewardship. Yet, whilst herds are healthier and reliance on critical therapeutics has plummeted, the economic reward for this progress remains frustratingly elusive as producers continue to battle severe supply chain pressures.

A Decade of Veterinary Discipline

Reducing antibiotic use by nearly three-quarters over ten years is no small feat. The drop to 77.2 mg/PCU in 2025 represents a sustained, industry-wide effort involving vets, stockmen, and feed manufacturers. This transition has required substantial capital investment in housing, improved biosecurity protocols, and a fundamental shift in how disease pressure is managed on farm. Rather than relying on routine prophylactic treatments, producers have turned to targeted vaccination, better ventilation, and stricter hygiene to keep herds healthy.

This voluntary progress has been achieved without compromising animal welfare, proving that UK agriculture can self-regulate effectively when given clear targets. However, these structural improvements on farm carry a permanent cost. High-welfare, low-antibiotic systems are more expensive to run, requiring higher labour inputs and more sophisticated management. The tension arises when these rising production costs collide with a retail market unwilling to absorb them.

The Retail Squeeze and the Northern Irish Escalation

The friction between on-farm standards and retail pricing has come to a head in Northern Ireland, where farm unions have escalated pig producer concerns directly to Tesco. This move exposes the vulnerability of domestic producers who adhere to rigorous UK standards but find themselves squeezed by supermarket procurement strategies. When major retailers fail to return a fair price that reflects the true cost of production, the sustainability of the entire domestic supply chain is thrown into jeopardy.

This domestic tension is further complicated by global market movements. With the Food and Agriculture Organization (FAO) reporting that global food prices edged down in June, the pressure on UK supermarkets to keep shelf prices low will only intensify. In a softening global market, the temptation for retailers to source cheaper, lower-standard pork from overseas increases, leaving UK producers who have invested heavily in antibiotic reduction at a distinct competitive disadvantage.

The success of the UK pig sector in reducing antibiotic use demonstrates that British farming can deliver world-class standards of stewardship. However, the ongoing dispute with major retailers like Tesco indicates that high standards cannot be sustained on goodwill alone. If the market fails to reward producers for these achievements, there is a real risk of structural decline in the domestic herd, ultimately forcing the UK to rely on imports from countries with less stringent welfare and antibiotic controls. The industry must watch whether retailers will commit to long-term sourcing agreements that reflect the true cost of responsible production.
