Ref.: C.L.20.2023
The World Health Organization (WHO) presents its compliments to Member States and
has the honour to inform them that WHO is updating the estimates on the burden of foodborne
diseases to be published in 2025.
As part of the resolution under the Strengthening efforts on food safety (WHA73.5), WHO
will update the global burden of foodborne diseases estimates, and report incidence, mortality
and burden in terms of disability-adjusted life years (DALYs) at national, regional and
international levels.
Following WHO’s policy for data publication and prior to the official release of the final
estimates, WHO will consult with Member States to provide opportunity for review and input on
(i) national primary data sources where available, and (ii) individual country estimates derived
from the statistical model applied to the national primary data from all countries.
WHO will create a country-specific space within the WHO Country Portal dedicated to
this technical area of work where designated focal point(s) will have access to relevant technical
materials and information about the process, including documents on methodology,
decision-making processes, and country-specific data. Once the first stage is complete, the
official country consultation of WHO comparable estimates will be also conducted via the same
portal space.
Member States are requested to designate a focal point(s) who has relevant qualifications
... (see Annex 1). They may designate multiple focal points to cover a range of technical subjects
(i.e. diseases caused by microbiological hazards, parasites, or chemicals and toxins), and
determine, among them, one coordinator who will streamline communications with WHO as the
primary national focal point and liaise with other national focal points for sharing relevant
information and consolidating feedback.
When a primary accountability of food safety or foodborne diseases falls under a ministry
other than Ministry of Health (i.e. Ministry of Agriculture, National Food Safety Authority),
Member States are requested to share this request with other relevant ministries and identify a
most appropriate focal point(s).
Designation of the focal point(s), together with contact details (full name, title, affiliation
and email address) should be sent as soon as possible before the opening of the consultation to
[email protected] no later than 18 August 2023. Focal point(s) will then get instructions on
how to access the country consultation platform.

C.L.20.2023
The terms and conditions that apply to any data provided by countries to WHO is
... presented in Annex 2. By providing data to WHO, Member States confirm their understanding
and agreement of these terms and conditions.
In case any clarification or additional information is needed, an email can be sent to
Ms Yuki Minato (
[email protected] or
[email protected]).
The World Health Organization takes this opportunity to renew to Member States the
assurance of its highest consideration.

ANNEX 1
A SUGGESTED PROFILE SUITABLE
FOR A DESIGNATED NATIONAL FOCAL POINT(S)
The first global estimates of the incidence, mortality and disease burden in 2010 caused by
31 foodborne hazards was released in 2015.1,2 Three broad categories of hazards were included:
enteric hazards such as bacteria and viruses, parasitic hazards, and chemicals and toxins. Please see
below a list of hazards and causally related health states included for 2015 estimates.
For the next updates, WHO plans to include, at least as a minimum, the same 31 hazards and four
heavy metals, namely Arsenic, Cadmium, Lead and Methyl mercury. Other additional important
hazards and new health states will also be considered subject to further discussions and decisions.
As requested in the circular letter, WHO seeks a national focal point(s) for each country to receive
technical information materials and preliminary estimates of the burden of foodborne diseases.
WHO suggests its Member States consider seeking personnel(s) with the following knowledge and
qualifications to act as a focal point(s):
• Understanding and background in epidemiology, data science, health or bio-statistics, food
science, risk assessment of chemicals or pathogens.
• Familiarity with burden of disease assessment and associated metrics.
• Familiarity with health surveillance and epidemiological modelling.
Given a scope of hazards and disease areas, an engagement of multiple focal point(s) from more
than one ministry or technical agencies may be required depending in a situation in each
Member State.

– to publish the data, stripped of any personal identifiers (such data without personal identifiers being
hereinafter referred to as “the Data”) and make the Data available to any interested party on request (to
the extent they have not, or not yet, been published by WHO) on terms that allow non-commercial,
not-for-profit use of the Data for public health purposes (provided always that publication of the Data
shall remain under the control of WHO);
– to use, compile, aggregate, evaluate and analyse the Data and publish and disseminate the results
thereof in conjunction with WHO’s work and in accordance with the Organization’s policies and
practices.
– except where data sharing and publication is required under legally binding instruments (IHR, WHO
Nomenclature Regulations 1967, etc.), the Ministry of Health of your Country may in respect of
certain data opt out of (any part of) the above, by notifying WHO thereof in writing at the following
address,
[email protected], provided that any such notification shall clearly identify the data in
question and clearly indicate the scope of the opt-out (in reference to the above), and provided that
