“…On the other hand, more sensitive diagnostic methods such as seroepidemiological studies and immunohistochemical tests have proved to be even more reliable and accurate. Eichenberger et al () carried out a seroepidemiological survey of T. saginata cysticercosis and demonstrated prevalences of between 2 and 50 times higher through seroepidemiology than those obtained by routine meat inspection. In another study, Dorny et al () examined 1,164 serum samples collected from 20 export abattoirs in Belgium for circulating parasite antigen using a monoclonal antibody‐based sandwich enzyme‐linked‐immunosorbent assay (Ag‐ELISA) and found 36 (3.09%) serum samples to be positive in the Ag‐ELISA, while meat inspection on the same animals detected cysticerci in only 3 (0.26%) carcasses.…”

Background The aim of this review was to establish the current epidemiology of taeniosis, cysticercosis and trichinellosis among humans and animals in Iran by carrying out a comprehensive assessment of published articles reporting on these foodborne zoonotic diseases across the country. Methods The Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) guideline was used in the search for relevant published articles reporting on cysticercosis, taeniosis and trichinellosis in Iran using a number of appropriate key words. The search was conducted through PubMed, Web of Science, Google Scholar, SpringerLink, SCOPUS, WHOLIS, FAO and CDC. Published scientific articles including journals, books and book chapters reporting on cysticercosis, taeniosis and trichinellosis in Iran for the period between 1967 and 2018 were selected. Results A total of 37 articles met the search criteria and were incorporated in this review. Of these, 10 (27%) reported on human taeniosis, 15 (40.5%) on cysticercosis (10 on Taenia saginata and five on Taenia spp. cysticercosis) and 12 (32.5%) on trichinellosis. T. saginata was implicated in all human taeniosis cases. All Taenia spp. cysticercosis cases were reported among domesticated pigs and wild animals. A case of neurocysticercosis was reported in a male patient at Shohada Hospital in Tehran. Eleven (91.7%) of the 12 studies reported on trichinellosis among wild animals, while one (8.3%) study detected anti‐Trichinella IgG in 8 (2.2%) of the 364 at‐risk human beings tested. Nevertheless, most of these studies were carried out in northern Iran. Conclusion This review found T. saginata to be the most prevalent and of greater economic and public health significance in Iran. However, T. solium and Trichinella spp. were of little significance to human health. More studies should focus on other regions besides northern Iran.

“…Furthermore, the sensitivity of cysticercosis detection at post-mortem inspection also depends, to a certain extent, on the number of incisions made, particularly in the heart, which is a more important predilection site than mastication muscles (Dorny et al, 2000). When additional cuts (more than the mandatory requirement) in the heart were made during meat inspection, approximately a 2.5-fold higher cysticercosis detection rate was achieved (Eichenberger et al, 2011). Due to all these factors, published data suggested that in the EU post-mortem inspection-detected prevalence of bovine cysticercosis is roughly 3 to 10-fold lower than actually present (Dorny and Praet, 2007).…”

“…Alternative options to a change to a visual only system would be to cease incisions of the carcass, but increase inspection of the heart by making additional incisions. There is preliminary evidence that this practice could ameliorate the loss of sensitivity if incisions of carcass muscles were no longer done (Eichenberger et al, 2011).…”

Scientific Opinion on the public health hazards to be covered by inspection of meat (bovine animals)

A risk ranking process identified Salmonella spp. and pathogenic verocytotoxin-producing Escherichia coli (VTEC) as current high-priority biological hazards for meat inspection of bovine animals. As these hazards are not detected by traditional meat inspection, a meat safety assurance system for the farm-to-chilled carcass continuum using a risk-based approach was proposed. Key elements of the system are risk-categorisation of slaughter animals for high-priority biological hazards based on improved food chain information, as well as risk-categorisation of slaughterhouses according to their capability to control those hazards. Omission of palpation and incision during post-mortem inspection for animals subjected to routine slaughter may decrease spreading and cross-contamination with the high-priority biological hazards. For chemical hazards, dioxins and dioxin-like polychlorinated biphenyls were ranked as being of high potential concern; all other substances were SUMMARYFollowing a request from the European Commission, the EFSA Panel on Biological Hazards (BIOHAZ) was asked to deliver a Scientific Opinion on the public health hazards to be covered by inspection of meat from several animal species, with the contribution of the Panel on Contaminants in the Food Chain (CONTAM) and the Panel on Animal Health and Welfare (AHAW). Briefly, the main risks to public health that should be addressed by the meat inspection system were identified and ranked; the strengths and weaknesses of the current meat inspection system were evaluated; recommendations were made for inspection methods addressing hazards not covered by the current meat inspection system; and recommendations for adaptations of inspection methods and/or frequencies of inspection that provide an equivalent level of protection were made. In addition, the implications for animal health and animal welfare of any proposed changes to current inspection methods were assessed. This opinion covers the inspection of meat from bovine animals.The Terms of Reference from the European Commission requested two opinions, one covering bovine animals under six weeks old and the other covering bovine animals over six weeks old. It was determined that within a true risk-based meat inspection concept, it is not necessary to design and apply a separate meat inspection system for individual bovine species or farming systems or animal age categories. Rather, a universal meat inspection framework can be designed and applied that would allow risk categorisation of animals based on individual farm-related food chain information (FCI), which also includes farming system and animal age category components. Furthermore, the available data from the National Residue Control Programmes (NRCPs) do not readily discriminate between the two age groups. Therefore, the assessment did not differentiate between these two age groups in terms of biological hazards, chemical residues and contaminants, and subsequently a single opinion is provided.Decision trees were developed and used for pr...

“…Detection rate of carcases with light infestation (1-10 cysts) of T. saginata cysticerci is believed to be low (27 %), rising to 43 % for animals with 11-20 cysts and 78 % when 20 or more cysts are present (EFSA, 2004). By adding additional cuts to the inspection of the heart, the number of cases detected was increased by twofold (Eichenberger et al, 2011).…”

In this report harmonised epidemiological indicators are proposed for food-borne biological hazards to public health that are related to bovine animals and meat thereof and that can be addressed within meat inspection. These hazards include Salmonella, pathogenic verocytotoxin-producing Escherichia coli, Cysticercus (Taenia saginata) and mycobacteria. An epidemiological indicator is defined as the prevalence or the concentration of the hazard at a certain stage of the food chain or an indirect measure of the hazard that correlates with the human health risk caused by the hazard. The indicators can be used by the European Commission and the Member States to consider when adaptations to meat inspection methods may be required, and to carry out risk analysis to support such decisions. It is foreseen that the indicators will be used in the bovine carcase meat safety assurance system outlined in the EFSA Scientific Opinion, particularly to help categorise farms/herds and slaughterhouses according to the risk related to the hazards as well as setting appropriate specific hazard-based targets in/on bovine carcases and, when appropriate, in bovine farms/herds. Depending on the purpose and the epidemiological situation risk managers should decide on the most appropriate indicator(s) to use, either alone or in combination, at national, regional, slaughterhouse or farm/herd level. It is recommended that risk managers should define the harmonised requirements for controlled husbandry conditions of farms, and the requirements for food chain information. Member States are invited to organise training regarding the implementation of the indicators and the reporting of data generated by the implementation in accordance with Directive 2003/99/EC. The proposed indicators should be regularly reviewed in the light of new information and the data generated by their implementation. © European Food Safety Authority, 2013.
