Farmers in Scotland are investigating the impact of foodborne pathogens on livestock and ways to minimise the risks of these pathogens. A study highlights the need for effective interventions.
Scottish livestock farmers are working to gain more information to better understand the impact of foodborne pathogens on the sector and minimise the risks posed to their animals by these pathogens. Consumer perceptions of foodborne pathogens are also a major concern for farmers. A comprehensive study on this topic aims to provide potential solutions for managing livestock risks on Scottish farms.
Purpose and methodology of the study
The study was conducted by the Moredun Research Institute in collaboration with the Scottish Government, Food Standards Scotland and Sefari. The study aims to comprehensively examine the ways in which foodborne pathogens enter and spread livestock, farmers’ attitudes towards these pathogens and the interventions that should be taken.
The study highlights the need to consider the biological characteristics, transmission routes and environmental conditions of each pathogen in order to understand the processes by which foodborne pathogens spread in animals.
Pathogens usually multiply in the intestines of animals and are excreted from the body with feces. Therefore, hygiene and management practices that minimize contact with animal feces are of great importance. The study revealed that factors such as the types of shelters used on farms, bedding materials and animal density are effective in this regard.
Biosecurity and hygiene practices
Hygiene and biosecurity practices on the farm play a critical role in preventing the spread of pathogens. According to the study, measures such as quarantining newly arrived animals, strict implementation of cleaning procedures and use of personal protective equipment can help prevent the spread of pathogens. In addition, the use of disinfectants and biosecurity measures to reduce the effect of pathogens are also recommended.
Intervention methods to minimize the threat
The research report recommends various intervention methods for farmers to cope with the pathogen risk. These include the use of heat and steam cleaning methods to inactivate pathogens resistant to disinfectants such as Cryptosporidium, storing farm manure in appropriate conditions and using cattle vaccines. In particular, vaccines that prevent the spread of foodborne pathogens such as Salmonella and E. Coli are seen by farmers as a preventive measure against production diseases. Surveys show that a vaccination strategy can not only protect public health but also reduce production losses.
Results of the study and future perspectives
The study has shown that the best way to reduce the risk of pathogens on farms is to fully understand the routes by which pathogens enter, are transmitted, multiply and spread. Furthermore, knowing the prevalence of specific pathogens provides valuable information on which interventions should be prioritized in combating these pathogens. For example, eDNA sampling methods used to monitor pathogens shed in faeces can provide important data on pathogen load on the farm.
In conclusion, biosecurity practices and the use of vaccines on farms stand out as effective solutions in combating foodborne pathogens. The study shows that Scottish farmers need to take more conscious steps to minimise the spread of foodborne pathogens, and that this has reached an important turning point in ensuring the sustainability of the sector.
