What is JEMRA?JEMRA Joint FAO/WHO Expert Meetings on

Microbiological Risk Assessment

Established in 2000 in response to a request from Codex

for an FAO/WHO expert body to provide scientific advice

on microbiological hazards in foods


3/13



Purpose of JEMRA

To provide sound scientific advice on microbiological issues

to FAO, WHO, Codex, and FAO and WHO member countries

To address specific microbiological risk management questions

from the Codex committees

To develop adaptable risk assessments and data resourcesfor countries to use in conducting their own risk assessments


4/13



JEMRA activities

Generation of scientific information risk assessments

Elaboration of guideline documents

Data collection and generation

Use of risk assessment within a risk management framework

Information and technology transfer


5/13



JEMRA risk assessments

Focus on specific pathogen-commodity combinations

Examples of pathogen-commodity combinations considered to

March 2005 include:

Salmonella spp. in broilers Salmonella enteritidis in eggs

Listeria monocytogenes in ready-to-eat foods

Campylobacterspp. in broiler chickens Vibrio spp. seafood

Enterobacter sakazakiiin powdered infant formula


6/13



Further aim of JEMRA

To provide guidance on how risk assessment can be used

effectivelybyrisk managers as a decision support tool

Risk analysis is an integral part of the Codex standard-setting

process, including microbiological risk assessment.


7/13



Membership of JEMRA

As a multidisciplinary approach is required, implementing the

programme of work of JEMRA requires the input of experts in

a number of fields.

"call for experts" is issued, aimed at identifying specialists in

microbiology, epidemiology, mathematical modelling, public

health, food technology, veterinary medicine, risk assessment

and other relevant areas.

Experts are appointed in their personal capacity and not as

representatives of their country or of the institution by which they

may be employed.


8/13



How does JEMRA work?

Usually two expert meetings are held per year

Working groups are established to carry out work

between meetings

Progress reports are made available while the risk assessment

is ongoing

Final reports are peer-reviewed before publication

The need for an international

approach to MRA

The microbiological risk assessment process (MRA) is a means

of providing an estimate of the probability and severity of illnessattributable to a particular pathogen-commodity combination.

The carrying out of an MRA, particularly a quantitative MRA,

is recognized as a resource-intensive task requiring a

multidisciplinary approach.


10/13



The need for an international

approach to MRA (cont.)

Often, it is not within the capacity of many, perhaps even most,

countries to carry out a complete quantitative MRA.

Food-borne illness is among the most widespread public health

problems and creates social and economic burdens that countries

need to address.

This need has led FAO and WHO to undertake a programme of

activities to address the issue of MRA at the international level.


11/13



Strengths of the international

approach to MRA

Enables identification of areas that are similar or common to a

particular region or even to all countries

Addresses issues of international concern or issues of concern toa large group of countries

Enables the identification of available data on a global scale and

the areas where knowledge and data are lacking

Provides the highest standards of information as this work is undertaken

with the assistance of internationally recognized experts in the field

Undertaking this work at the international level results in the provision ofvaluable information on particular pathogen-commodity combinations for

use by risk managers at both the national and international levels and thus

facilitates optimal use of limited resources


12/13



Limitations of

international approach to MRA

Risk assessment at the international level is substantially different

from risk assessment at the national level. It cannot consider thesituation in all countries and therefore tends to be more generic in

nature.

A globally applicable risk estimate, i.e. one risk estimate that is

valid for all countries, cannot be produced.
