In 2011, the European Food Safety Authority (EFSA) introduced harmonised epidemiological indicators (HEIs) for pigs to be utilised as part of the risk-based meat inspection within the meat safety assurance framework. However, the application of HEIs is not regulated by law. HEIs enable risk categorisation of farms regarding the main foodborne biological hazards associated with pigs and pork in Europe: Salmonella, Yersinia enterocolitica, Toxoplasma gondii, Trichinella and Cysticercus cellulosae. A questionnaire was developed to evaluate the current implementation of HEIs for pigs in Europe and was targeted at official veterinarians and food business operators experienced or involved in the official monitoring and surveillance at abattoirs. The study examined which of the HEIs for pigs were applied by asking for i) the corresponding private and/or official monitoring and surveillance systems (MoSSs) in place, ii) the stages at which the testing was conducted, iii) the diagnostic methods and iv) the sample materials used. In general, 88% of the respondents stated monitoring for Salmonella, 10% for Yersinia enterocolitica, 2% for Toxoplasma gondii, 90% for Trichinella and 31% for Cysticercus cellulosae was in place. In most cases, MoSSs for Salmonella, Trichinella and Cysticercus cellulosae were in place at abattoir level. Monitoring for these pathogens at abattoir level is already regulated by EU legislation. When corresponding HEIs for a regulated pathogen existed, they largely overlapped with the testing regime of the MoSSs. HEIs for the same pathogens that focus on a different stage of the food chain were mostly declared by respondents to not have been implemented; the same situation was found with HEIs for the other pig-associated hazards, Yersinia enterocolitica and Toxoplasma gondii. The results also revealed some alarming inconsistencies in the mandatory monitoring prescribed by EU regulations. Some respondents demonstrated a lack of understanding regarding diagnostic procedures, failing to correctly match diagnostic methods with the appropriate sample materials or vice versa. While HEIs provide valuable data, especially in terms of a novel risk-based meat safety assurance system, this survey showed that they are currently underutilised for pigs in Europe.
