Indicator code: E220200.T
Infections or intoxications due to microbiologically contaminated food (trichinellosis, salmonellosis, campylobacter infections etc.). An outbreak is the exposure of a group of persons with the contaminated food as the common origin. It is understood that national definitions and registration practices vary significantly. In some countries, an outbreak is counted when more than 15 cases are involved._
Data collected annually, reference period: 31 December.
Institute of Public Health.
The number of reported outbreaks more than doubled in 2011 as compared to previous years, which
might be due to an adapted outbreak investigation procedure at the FASFC and/or increased
sensibility by consumers, especially after the death of an adolescent in a French fastfood
restaurant and the German E. coli O104:H4 outbreak involving many deaths
Reduction in year 2012 caused by the reduction in number of salmonella outbreaks due to successful
implementation of veterinary programmes for infection control in poultry.
The registration of outbreaks generally includes more than 10 cases.
Description of the types of outbreaks covered by the reporting:
All general domestic food- and waterborne outbreaks are reported in Finland. Illness of more than
two persons from single source is considered a cluster and a suspected outbreak. Sporadic cases
(except for botulism) and infections acquired abroad are not included in the food poisoning
register, whereas they are included in the infectious disease register. Family outbreaks are
reported if commercial foodstuffs are supposed to be a source of illness or several persons are at
risk. Obligatory reporting involves definite communicable diseases and traditional foodborne agents
such as those causing intoxications.
Breaks in time series:
2010: The increase in number of outbreaks since year 2010 has been due to the change of the
reporting format in 2009.
2012: Since 2012, the category of the microbiological food-born diseases has been changed and
traditional ICD-10 category (A05) was expanded and codes T61, T62 and T64 were added. Since this
time a permanent growth of cases has been registered.
as of March 1, 2015).
Coverage: Data on outbreaks are collected by the Robert Koch-Institute in compliance with the
Infectious Disease Control Act. According to õ6 Infectious Disease Control Act in Germany cases are
notifiable if two or more persons have the same disease (e.g. food poisoning) and it is supposed
that these diseases have the (probably) common origin.
The reported figures are potential foodborne outbreaks (2 and more cases). This means, because of
the germ an infection or intoxication due to microbiologically contaminated food is assumed. The
notifiable germs that could be transmitted through food are: Clostridium botulinum, Brucella spp.,
Campylobacter spp., Cryptosporidium parvum, Escherichia coli, enterohemorrhagic Escherichia coli
(EHEC), Francisella tularensis, Giardia lamblia, Hepatitis-A and Hepatits-B, Listeria monocytogenes,
Salmonella enterica Serovar Paratyphi A-C, Salmonella enterica Serovar Typhi, Salmonella spp.,
Shigella spp., Trichinella spiralis, Yersinia enterocolitica and Vibrio cholera.
Due to often transmissions from person to person outbreaks on Norwalk-like virus are excluded.

only confirmed outbreaks of foodborne illness are included. This has resulted in some increase in
the numbers of total confirmed cases and a reduction in the numbers of outbreaks in 5 out of six

enteritis caused by opportunistic enterobacteria, etiologically nerasshifrovanye acute intestinal
diseases, etc.) transmitted by microbiologically contaminated food are included into the data.
In the republic of Moldova, the term ?intestinal disease outbreak? is used when 5 and more cases are
registered (in the hospital - two or more cases).
According to the documents of the Ministry of Health of the Republic of Moldova, cases of food
poisoning are reported to the Ministry of Health and the National Center of Public Health within 24
hours from the time of detection. The procedure of collecting and transmitting data is as follows:
A medical professional of any medical institution submits an emergency notification (Form N58/e) to
the Regional Public Health Center (for each patient suspected of the disease or with a primary
diagnosis of an acute intestinal disease including food intoxication). Based on these submissions,
an epidemiological study is conducted to establish the fact of a disease outbreak.
Regional Centres of Public Health, in turn, inform the Ministry of Health and the National Center of
Public Health within 24 hours from the time of detection and registration of acute intestinal
diseases and food poisoning with 5 or more victims (in the hospital - with 2 or more victims).
Source of data: After the completion of epidemiological studies (see above), Regional Centres of
Public Health send final reports of the outbreak investigation to the National Center of Public
Health. These reports are analysed and used as an official source of information about intestinal
disease outbreaks at both national and international levels.
In order to obtain timely information, investigation and registration of intestinal disease
outbreaks the guidelines \On information
are involved. Most outbreaks are small \family (household) outbreak\" (3-5 cases) associated with
consumption of eggs prepared without appropriate heat treatment."

involved. Since 2009, an outbreak is counted when more than 15 people are involved.
