‘Unexpected’ number of AMR genes found on pig farm
This study was carried out during a single produciton cycle on a commercial pig farm.

New study highlights extent of AMR gene ‘pollution’ in livestock production

Researchers from Scotland’s Rural College (SRUC) have discovered a high number of antimicrobial resistance (AMR) genes in pig faeces at a commercial farm.

Antimicrobial agents are used regularly to control disease in livestock, but little is known about how this impacts antimicrobial resistance gene dynamics. This has raised concerns about the possibility of AMR genes being transferred from livestock to humans and into the environment.

Conducted alongside the University of Edinburgh’s Roslin Institute, this was the first longitudinal study of its kind. Carried out during a single production cycle on a commercial pig farm with high antimicrobial usage.

In total, 144 different genes were identified. Individual genes were present in the tens, hundreds and thousands of millions per gram of pig faeces. SRUC states that this unexpected discovery highlights the extent of AMR gene pollution in livestock production and the environment.

The results also suggested that the genes had become integrated into the faecal microbial community, as AMR gene counts remained relatively stable over time.

However, despite these high and somewhat stable levels of AMR genes, the antimicrobials used were still effective in controlling production-limiting diseases on the farm.

Professor Michael Hutchings, head of animal and veterinary sciences at SRUC, commented: “At the start of the study we hoped to find two or three genes to follow their numbers through the pig production cycle. The richness of AMR genes and their numbers were unexpected.”

World Bee Day celebrations begin

News Story 1
 Today (20 May) marks the fifth annual World Bee Day, which raises awareness of the importance of bees and pollinators to people and the planet. Observed on the anniversary of pioneering Slovenian beekeeper Anton Jana's birthday, this year's celebration is themed: 'Bee Engaged: Celebrating the diversity of bees and beekeeping systems'.

Organisations and people celebrating the day will raise awareness of the accelerated decline in pollinator diversity, and highlight the importance of sustainable beekeeping systems and a wide variety of bees. Slovenia, the initiator of World Bee Day, will be focusing on teaching young people about the significance of pollinators.

Further avian flu cases confirmed

Three cases of highly pathogenic avian influenza (HPAI) H5N1 have been confirmed in recent days, bringing the total number of cases in England to 98.

On Thursday, the APHA confirmed two cases of HPAI H5N1 near Redgrave, Mid Suffolk and Market Weston, West Suffolk. A case H5N1 was also confirmed in poultry at a premises near Southwell, Newark and Sherwood, Nottinghamshire.

Protection and surveillance zones are in place around the affected premises. Further details are available at
