Poultry roundworms have re-emerged in European countries due to noncaged housing, impacting bird welfare and productivity. The Swedish Egg Association initiated a control program in 2009, but its data have not been fully explored, and understanding of producer perception is inadequate. This study addresses these issues through analyzing program data and conducting an online survey. The findings highlight the need for strategic sampling, appropriate diagnostic tools, and education on anthelmintics use and resistance development.
Poultry roundworms have re-emerged in laying hens in many European countries due to the increase in noncaged housing. This is worrying because, at high parasite loads, Ascaridia galli can impact birds' welfare, health, and productivity. Worm control is therefore an important aspect of the successful management of the egg production industry. In 2009, the Swedish Egg Association initiated a voluntary control program to tackle the problem and reduce the appearance of worms in table eggs by encouraging producers to submit fecal samples for analysis. Since the start of the program, its data have never been thoroughly explored. Moreover, after more than a decade of challenges, our understanding of how egg producers perceive worm infection is still inadequate. This study was therefore designed to address these issues. The research data in the present study are drawn from 2 sources. First, through the control program and second, through an online survey. We have summarized the control program's achievements and discussed its findings and limitations. Although this work contributes to existing knowledge of roundworm control in laying hens in general, it also identifies gaps in knowledge. In conclusion, the control program can be improved by incorporating more strategic sampling and utilizing well-suited diagnostic tools for better assessment of infection status. It is equally important to educate producers on anthelmintics (AH) use and the development of resistance.
