Biosecurity is an essential tool for rearing healthy animals. Biosecurity measures (BMs) are well known in poultry production, but it is difficult to assess actual implementation on farms. The aims of this qualitative study were (1) to provide an overview of biosecurity implementation according to poultry farmers in Europe; and (2) to better understand the reported reasons and potential obstacles for not implementing the measures.

Article Synopsis
- A study in France aimed to estimate the seroprevalence of SARS-CoV-2 among the population using blood test samples, but it lacked detailed data on individuals' infection or vaccination status.
- Researchers developed a machine learning model to predict if individuals were infected or vaccinated based solely on serological test results from earlier cohorts.
- The findings revealed a significant increase in the percentage of vaccinated individuals and those infected with SARS-CoV-2 from 2021 to 2022, highlighting that vaccination played a crucial role in decreasing the overall seronegative population.
Enterococci are commensal intestinal bacteria and opportunistic pathogens in humans and animals. Enterococcus-associated diseases are an emerging health issue in poultry. The aim of this retrospective study was to assess the occurrence of enterococci in poultry in France with regard to the manifested diseases and the affected avian species.

Eighty-four flocks of layer hens kept in cages and 142 broiler flocks were included in this study. For each production type, a questionnaire was submitted to farmers and fecal samples were taken to assess the L.
