Today (2022-07-10)
I am editing handouts of foodborne illness, and I get some useful statistical data from the ECDC
For example
Listeriosis - Annual Epidemiological Report for 2017
Then I check the copyright, and get this:
ECDC Copyright and Limited Reproduction Notices
There are some reminders, however, roughly most are under CC-BY 4.0
Great! Beside the US CDC, here is one more great database for editing my teaching materials.
Listeria infections in the EU in 2015
