Antibiotic use in livestock farming decreases, but not everywhere

The use of antibiotics in Dutch livestock farming has dropped by 70 percent since 2009. This has led to a reduction in antibiotic resistance among farm animals. However, experts warn that further steps are needed, particularly in tackling farms that consistently use excessive antibiotics.

Effects of reduced antibiotic use

Researchers at Wageningen Bioveterinary Research (WBVR) have observed positive effects from the reduced use of antibiotics. For instance, there has been a significant decrease in resistant bacteria such as ESBL-producing E. coli in broilers, which is crucial for public health. Nevertheless, some bacteria, such as campylobacters, have shown little to no reduction in resistance. According to Kees Veldman, head of the National Resistance Laboratory, long-term research remains necessary to fully understand the impact of reduced usage.

Consistent high users remain a concern

According to Dick Heederik of the Stichting Diergeneesmiddelen Autoriteit (SDa), some farms continue to operate consistently above the established norms. While the average antibiotic use per sector has dropped significantly, certain poultry farms still administer 25 to 35 daily doses per year, compared to a benchmark of 10. Addressing these high users involves quality programs and tailored guidance aimed at further reduction.

Challenges in specific sectors

The veal sector remains problematic due to the so-called crèche effect: young animals from different countries bring various infections, resulting in high antibiotic use. The rabbit and turkey sectors also struggle to stabilize their usage. Coaches are being deployed to support these sectors in achieving lower antibiotic use.
