The European Union One Health 2020 Zoonoses Report
Abstract
This report of the EFSA and the European Centre for Disease Prevention and Control presents the results of zoonoses monitoring activities carried out in 2020 in 27 EU Member States (MS) and nine non-MS. Key statistics on zoonoses and zoonotic agents in humans, food, animals and feed are provided and interpreted historically. Two events impacted 2020 MS data collection and related statistics: the Coronavirus Disease 2019 (COVID-19) pandemic and the withdrawal of the United Kingdom from the EU. In 2020, the first and second most reported zoonoses in humans were campylobacteriosis and salmonellosis, respectively. The EU trend for confirmed human cases of these two diseases was stable (flat) from 2016 to 2020. Fourteen of the 26 MS reporting data on Salmonella control programmes in poultry met the reduction targets for all poultry categories. Salmonella results for carcases of various species performed by competent authorities were more frequently positive than own-checks conducted by food business operators. This was also the case for Campylobacter quantification results from broiler carcases for the MS group that submitted data from both samplers, whereas overall at EU level, those percentages were comparable. Yersiniosis was the third most reported zoonosis in humans, with 10-fold less cases reported than salmonellosis, followed by Shiga toxin-producing Escherichia coli (STEC) and Listeria monocytogenes infections. Illnesses caused by L. monocytogenes and West Nile virus infections were the most severe zoonotic diseases with the highest case fatality. In 2020, 27 MS reported 3,086 foodborne outbreaks (a 47.0% decrease from 2019) and 20,017 human cases (a 61.3% decrease). Salmonella remained the most frequently reported causative agent for foodborne outbreaks. Salmonella in 'eggs and egg products', norovirus in 'crustaceans, shellfish, molluscs and products containing them' and L. monocytogenes in 'fish and fish products' were the agent/food pairs of most concern. This report also provides updates on tuberculosis due to Mycobacterium bovis or Mycobacterium caprae, Brucella, Trichinella, Echinococcus, Toxoplasma, rabies, Coxiella burnetii (Q fever) and tularaemia.

The left side of the diagram shows the five most commonly reported Salmonella serovars involved in human salmonellosis cases acquired in the EU: S. Enteritidis (blue), S. Infantis (green), S. Typhimurium (orange), monophasic S. Typhimurium (
1 ,4,[5],12:i:‐) (violet) and S. Derby (magenta). Animal and food data from the same source were merged: ‘broiler’ includes isolates from broiler flocks and broiler meat, ‘bovine’ includes isolates from bovines for meat production and bovine meat, ‘pig’ includes isolates from fattening pigs and pig meat, ‘turkey’ includes isolates from fattening turkey flocks and turkey meat, and ‘layers’ includes isolates from laying hen flocks and eggs. The right side shows the five sources considered (broiler, bovine, pig, turkey and layers). The width of the coloured bands linking sources and serovars is proportional to the percentage of isolates of each serovar from each source.

These distribution maps have been built based on data from reports (EFSA and ECDC, 2015a, b, 2016, 2017, 2018a, 2019, 2021).



Intermediate hosts included on the map are cattle, deer, goats, horses, moose, mouflons, pigs, reindeer, sheep, water buffalos and wild boars. Because of the co‐endemicity with Echinococcus multilocularis, pigs were excluded from Poland, Romania, Slovakia and Slovenia data when Echinococcus species information was not reported.


Note: the number of MS reporting outbreaks is shown at the bottom (N). Outbreaks reported by the United Kingdom are included for the years 2010–2019.

Note: the number of MS reporting outbreaks is shown at the bottom (N). Cases involved in outbreaks reported by the United Kingdom are included for the years 2010–2019. Cases involved in both strong‐evidence outbreaks and weak‐evidence outbreaks are included in the figure.


Note: * indicates countries with a statistically significant trend (p < 0.05) over the period. Dark red and light red representing strong‐ and weak‐evidence outbreaks, respectively. Blue has been used to show both the trend line and the secondary Y‐axis representing the outbreak reporting rate. This was adopted for Latvia, Lithuania, Malta and Slovakia, in order to highlight a scale that is different to that of the other countries.

Note: Only FBO reported by EU Member States are shown in the figure. Marine biotoxins includes ciguatoxin and other unspecified marine toxins.
Other viruses includes Tick‐borne encephalitis virus (TBE), Hepatitis E and other unspecified viruses. Other bacterial agents includes Vibrio parahaemolyticus, Enteropathogenic Escherichia coli (EPEC) and other unspecified bacteria. Other parasites includes Anisakis, Giardia and Enterocytozoon bieneusi. Other causative agents includes lectin.

Note: The table may be read by column (country) or by row (causative agent). The number at the end of each row is the number of countries that reported for 2020 a given causative agent for outbreaks in 2020 while the number at the top of each column indicates refers to the number of causative agents identified in outbreaks by a given country in 2020.

Causative agents are shown in different colours. The size of each sector is proportional to the number of outbreaks (internal circle) and human cases (external circle) involved in outbreaks. The number of cases is shown inside the circle. The number of outbreaks is shown outside the circle.Information on the number of involved cases was not available for one outbreak in Germany caused by norovirus and for nine outbreaks from Ireland caused by Hepatitis A, Shiga toxin‐producing E. coli and an unknown agent.

Note: The orange line (right axis) in the graphs represents the Salmonella outbreak reporting rate and was measured on the same scale for all MS (except for Slovakia), to allow a direct comparison between countries. The blue bars show the yearly trend in terms of absolute numbers of Salmonella outbreaks (left axis), using the most appropriate scale for each country.Blue has been used to show both the trend line and the secondary Y‐axis representing the outbreak reporting rate. This was adopted for Slovakia to highlight that the scale was different from the other countries.* Indicates countries with a statistically significant trend (p < 0.05) over several years.

Note: only causative agents and countries with statistically significant trends and more than five outbreaks reported per year, on average are shown.

Note: only food vehicles and countries with statistically significant trends and more than five outbreaks reported per year, on average, are shown.
