amending the Annex to Implementing Regulation (EU) 2018/1882 concer ning listed diseases of 
aquatic animals and the list of species and groups of species posing a considerable risk for the spread 
of those listed diseases 
(Text with EEA relevance) 
THE EUR OPEAN COMMISSION,
Havi ng regar d to the Treaty on the Functioning of the European Union,
Havi ng regard to Regulation (EU) 2016/429 of the European Parliament and of the Council of 9 March 2016 on 
transmissible animal diseases and amending and repealing certain acts in the area of animal health (‘Animal Health 
Law’) (1), and in particular Article 8(2), Article 8(3), and Article 8(4), point (b) thereof,
Whereas:
(1) Regulation (EU) 2016/429 lays down rules for the prevention and control of diseases, which are transmissible to 
animals or humans, including rules for the prioritisation and categor isation of liste d diseases that are of concer n at 
Union level. Those rules for the prevention and control of listed diseases apply to species and groups of species, 
which can transmit the liste d diseases, by virtue of either being suscep tible to them or by acting as vect ors. Those 
species and groups of species are liste d in the table in the Annex to Commission Implementing Regulation 
(EU) 2018/1882 (2), in accordance with the criteria laid down in Article 8 of Regulation (EU) 2016/429.
(2) The European Food Safety Author ity (EFSA) has provided scientific advice in its Scientifi c Opinions of 1 August 
2023 , concer ning species of fish (3), molluscs (4), and crustaceans (5), which may act as vectors of diseases falling 
within the scope of Regulation (EU) 2016/429.
(3) It is, theref ore, timely and impor tant, to review the list of vect ors of the aquatic diseases listed in the table set out in 
the Annex to Implementing Regulation (EU) 2018/1882, taking into account the scientific advice provi ded by EFSA , 
as well as the criteria laid down in Article 8 of Regulation (EU) 2016/429 whic h specifi cally stipulates that the list is 
to compris e those animal species, or groups of animal species whic h pose a considerable risk for the spread of 
specifi c liste d diseases. According to the working definition set out in the EFSA Scientific Opinions, vect or species 
are those species which have been demonstrate d to transmit the causative agent of a listed disease to susceptible 
species. Such vector species clearly present a considerable risk for the spread of listed diseases.

control rules to categ ories of listed diseases and establishing a list of species and groups of species posing a considerable risk for the 
spread of those listed diseases (OJ L 308, 4.12.2018, p. 21), ELI: https://eur -lex.europa.eu/eli/reg_impl/2018/1882/oj

2024/216  12.1.2024ELI: http://data.europa.eu/eli/reg_im pl/2024/216/oj 2/4(4) In so far as the risk posed by the vect or species whic h have been identif ied in the EFSA Scientific Opinions can be 
manage d by the compet ent author ities of Members State s, those vector species should be liste d in the fourth 
column of the table set out in the Annex to Implementing Regulation (EU) 2018/1882. In addition, the vect or 
species whic h are currently listed in that column, and which have not been identif ied by EFSA as having 
demonstrated the ability to transmit the causative agent of a listed disease of aquatic animals to suscep tible species, 
should be delet ed from that column. The list of vect or species for the aquatic diseases set out in the Annex to 
Implementing Regulation (EU) 2018/1882 should, theref ore, be amended according ly.
(5) Moreover , the World Org anisation for Animal Health (WOAH) has recently reviewed the aquatic species, which are 
susceptible to infection with Mar teilia refringens. A revised list of species which are susceptible to that disease is set 
out in Article 11.4.2. of the Aquatic Animal Health Code (6). As this disease is also currently liste d in the table set 
out in the Annex to Implementing Regulation (EU) 2018/1882, the Commission has reviewed the Repor t of the 
WOAH ad hoc group on susceptible species to infection with WOAH liste d diseases (7), whic h led to the revised list 
of species, which is set out in the Aquatic Animal Health Code.
(6) Following that review by the Commission, it is appropr iate to amend the list of species and groups of species, whic h 
is set out in the third column of the table in the Annex to Imp lementing Regulation (EU) 2018/1882, concer ning 
infection with Mar teilia refrin gens. This amendment takes the lates t scientifi c knowle dge into account and seeks to 
achi eve an appropr iate level of converg ence with WOAH standards, while still taking previous risk management 
decisions concer ning two species of mussels, namely Mytilus edulis and Mytilus galloprovincialis, into account.
(7) That list should theref ore reflect the list of suscep tible species set out in Article 11.4.2. of the WOAH Aquatic 
Animal Health Code, with the excep tion of the species Mytilus edulis and Mytilus galloprovincialis.
(8) The measures provid ed for in this Regulation are in accordance with the opinion of the Standing Committ ee on 
Plants, Animals, Food and Feed,
HAS ADOPTED THIS REGUL ATION:
Article 1
The Annex to Implementing Regulation (EU) 2018/1882 is amended in accordance with the Annex to this Regulation.
Article 2
This Regulation shall enter into force on the twentieth day followi ng that of its publication in the Official Journal of the 
European Union.
This Regulation shall be binding in its entirety and directly applicable in all Member States.
