PARLEMENT EUROPEEN - Réponse à question E-002683-19 Measures taken in response to the food warning issued following the listeria outbreak in Andalusia. EFSA 17/09/19 Quantitative risk assessment of Listeria monocytogenes in a traditional RTE product. EFSA 16/07/19 Evaluation of listeriosis risk related with the consumption of non‐prepackaged ready‐to‐eat (RTE) cooked meat products handled at retail stores in Greece. EFSA 03/07/18 Listeria monocytogenes: update on foodborne outbreak.

Frozen corn and possibly other frozen vegetables are the likely source of an outbreak of Listeria monocytogenes that has been affecting Austria, Denmark, Finland, Sweden, and the United Kingdom since 2015.

EFSA 03/07/18 Listeria monocytogenes: update on foodborne outbreak

Experts used whole genome sequencing to identify the food source, which initially was thought to be limited to frozen corn. As of 8 June 2018, 47 cases including nine deaths had been reported. The same strains of L. monocytogenes have been detected in frozen vegetables produced by the same Hungarian company in 2016, 2017 and 2018. This suggests that the strains have persisted in the processing plant despite the cleaning and disinfection procedures that were carried out. The available information confirms the contamination at the Hungarian plant. New cases could still emerge due to the long incubation period of listeriosis (up to 70 days); the long shelf-life of frozen corn products; and the consumption of frozen corn bought before the recalls and eaten without being cooked properly. EFSA 03/07/18 Multi-country outbreak of Listeria monocytogenes serogroup IVb, multi-locus sequence type 6, infections linked to frozen corn and possibly to other frozen vegetables – first update.

An outbreak of invasive Listeria monocytogenes (L. monocytogenes) infections confirmed by whole-genome sequencing (WGS) and linked to frozen corn and possibly to other frozen vegetables has been ongoing in five EU Member States (Austria, Denmark, Finland, Sweden and the United Kingdom) since 2015.

EFSA 03/07/18 Multi-country outbreak of Listeria monocytogenes serogroup IVb, multi-locus sequence type 6, infections linked to frozen corn and possibly to other frozen vegetables – first update

As of 15 June 2018, 47 cases have been reported and nine patients have died due to or with the infection (case fatality rate 19%). WGS analysis of 29 non-human L. monocytogenes isolates found them to be closely related to the multi-country human cluster of L. monocytogenes serogroup IVb, multi-locus sequence type 6 (ST6). The majority of the non-human isolates were obtained from 2017 season products: mainly frozen corn (13 samples), followed by frozen vegetable mixes including corn (8 samples), frozen spinach (1) and frozen green beans (1). Only one isolate was reported from a frozen vegetable mix produced in 2016, while three isolates were obtained from spinach products produced in 2018. EFSA 13/07/17 Closing gaps for performing a risk assessment on Listeria monocytogenes in ready-to-eat (RTE) foods: activity 2, a quantitative risk characterization on L. monocytogenes in RTE foods; starting from the retail stage.

EFSA 12/08/14 Analysis of the baseline survey on the prevalence of Listeria monocytogenes in certain ready-to-eat foods in the EU, 2010-2011 Part B: analysis of factors related to prevalence and exploring compliance. A European Union-wide baseline survey on Listeria monocytogenes was carried out in 2010 and 2011 with the aim of estimating the European Union-level prevalence of Listeria monocytogenes in certain ready-to-eat (RTE) foods at retail.

EFSA 12/08/14 Analysis of the baseline survey on the prevalence of Listeria monocytogenes in certain ready-to-eat foods in the EU, 2010-2011 Part B: analysis of factors related to prevalence and exploring compliance

A total of 3 053 batches of packaged (not frozen) hot or cold smoked or gravad fish, 3 530 packaged heat-treated meat products and 3 452 soft or semi-soft cheeses were sampled from 3 632 retail outlets in 26 European Union Member States (MS) and one country not belonging to the European Union. Two fish product samples from the same batch were analysed upon arrival at the laboratory as well as at the end of shelf-life, whereas the meat products and the cheese samples were analysed at the end of shelf-life. All 13 088 food samples were examined for the presence of L. monocytogenes, in addition to the determination of the L. monocytogenes counts. A statistical model was developed for this purpose and is presented in the current report. EFSA 17/12/15 Campylobacter and Listeria infections still rising in the EU – say EFSA and ECDC.

Listeriosis infections reported in humans increased by 16% compared with 2013: there were 2,161 confirmed cases in 2014.

EFSA 17/12/15 Campylobacter and Listeria infections still rising in the EU – say EFSA and ECDC

Although this number is relatively low, the rise of reported listeriosis cases is of concern as the surveillance of these infections is focused on severe forms of the disease, with higher death rates than for other food-borne diseases, particularly among the elderly, and patients with a weak immune system. However, Listeria monocytogenes, the bacterium that causes listeriosis in humans and animals, seldom exceeded the legal safety limits in ready-to-eat foods – the most common foodborne source of human infections.

Campylobacteriosis remains the most commonly reported foodborne disease in the EU and has been so since 2005. The number of confirmed cases in the EU in 2014 was 236,851, an increase of 22,067 cases (10%), compared with 2013. “All main actors in the food chain need to act together to improve monitoring at EU level. PARLEMENT EUROPEEN - Réponse à question E-007891-15 Conséquences contre-productives de l'hygiénisme normatif (concerne Listeria) Dans un récent rapport qu'elle a rendu sur les zoonoses, c'est-à-dire sur les maladies d'origine animale, l'Autorité européenne de sécurité des aliments (AESA ou EFSA en anglais) a révélé que les victimes de la listeria sont de plus en plus nombreuses.

Les dernières statistiques disponibles sont sans appel: entre 2012 et 2013, le nombre de malades contaminés par cette bactérie a fait un bond de 8,6 %. Or, d'après ce rapport, «les infections signalées sont surtout des formes sévères et invasives de la maladie, qui présentent des taux de mortalité plus élevés que les autres maladies d'origine alimentaire.»

D'après les experts, l'une des causes de ce phénomène serait l'hygiénisme forcené des normes imposées par l'Union européenne car, à force d'aseptiser les chaînes de fabrication des aliments, l'agroalimentaire permet à une bactérie comme la listéria de proliférer d'autant plus rapidement qu'elle n'a plus de concurrence microbienne. EFSA 04/06/09 Proposed technical specifications for a survey on Listeria monocytogenes in selected categories of ready-to-eat fo. Type: Scientific Report of EFSA Question number: EFSA-Q-2008-415 Approved: 22 May 2009 Published: 04 June 2009 The European Food Safety Authority and its Task Force on Zoonoses Data Collection were requested by the European Commission to produce a proposal for technical specifications on a co-ordinated monitoring programme (a survey scheme) for Listeria monocytogenes in ready-to-eat (RTE) food.

EFSA 04/06/09 Proposed technical specifications for a survey on Listeria monocytogenes in selected categories of ready-to-eat fo

This survey should allow the comparison of L. monocytogenes contamination in RTE food in the Community and Member States and the verification of the Community food safety criteria for L. monocytogenes. The proposed technical specifications focus on sampling those categories of RTE food in which the highest rates of L. monocytogenes contamination have been observed in the European Union (EU): soft and semi-soft cheeses, smoked and gravad fish, and heat-treated meat products that are handled after heat treatment.

Zoonoses are infections and diseases that are naturally transmissible directly or indirectly, for example via contaminated foodstuffs, between animals and humans. In 2008, 27 Member States submitted information on the occurrence of zoonoses, zoonotic agents and food-borne outbreaks to the European Commission and the European Food Safety Authority. In 2008, salmonellosis was again the second most often reported zoonotic disease in humans accounting for 131,468 confirmed human cases. An important decline in the prevalence of S.
