EU Research – Risk characterisation of ciguatera poisoning in Europe

EFSA

The EuroCigua project main objective is to characterize the risk of Ciguatera Poisoning (CP) in Europe including several specific objectives: to determine the incidence of ciguatera in Europe and the epidemiological characteristics of cases; to assess the presence of ciguatoxin in food and the environment in Europe and to develop and validate methods for the detection, quantification and confirmation of the presence of ciguatoxin contaminated specimens.

This report compiles the activities carried out during the EuroCigua project from the signing in April 2016 until December 2020. The present document corresponds to Deliverable No. 6: “Final Scientific Report” on Risk characterization of ciguatera food poisoning in Europe of the Specific Agreement no. 1 “MANAGEMENT AND SCIENTIFIC COORDINATION” within the Framework Partnership Agreement GP/EFSA/AFSCO/2015/03 “Risk characterization of ciguatera food poisoning in Europe”.

EU – Shiga toxin-producing Escherichia coli (STEC) infection – Annual Epidemiological Report for 2019

ECDC

ECDC’s annual surveillance reports provide a wealth of epidemiological data to support decision-making at the national level. They are mainly intended for public health professionals and policymakers involved in disease prevention and control programmes.

Executive summary

  • For 2019, 29 EU/EEA countries reported 8 313 confirmed cases of Shiga toxin-producing Escherichia coli (STEC) infection.
  • The overall notification rate was 2.2 cases per 100 000 population.
  • After a stable period, the notification rate increased in 2018−2019.
  • The highest notification rates were reported in Denmark, Iceland, Ireland, Malta, and Norway.
  • The highest rate of confirmed cases was observed in 0–4-year-old children (10.3 cases per 100 000 population).

EU – Legionnaires’ disease – Annual Epidemiological Report for 2019

ECDC

Legionella_Plate_01

ECDC’s annual surveillance reports provide a wealth of epidemiological data to support decision-making at the national level. They are mainly intended for public health professionals and policymakers involved in disease prevention and control programmes.

Executive summary

  • Legionnaires’ disease remains an uncommon and mainly sporadic respiratory infection with an overall notification rate in 2019 for the EU/EEA of 2.2 cases per 100 000 population.
  • There is heterogeneity in notification rates between EU/EEA countries, with the highest rate reported by Slovenia (9.4 cases per 100 000 population).
  • The annual notification rate increased in recent years, from 1.4 in 2015 to 2.2 cases per 100 000 population in 2019.
  • There was a marginal decrease of less than 1% in the number of reported cases in 2019, compared with 2018.
  • Four countries (France, Germany, Italy, and Spain) accounted for 71% of all notified cases in 2019.
  • Males aged 65 years and above were most affected (8.4 cases per 100 000 population).
  • Only 10% of cases were culture-confirmed (10%) probably meaning that disease caused by Legionella species other than Legionella pneumophila is under-estimated.

Research – Lactic Starter Dose Shapes S. aureus and STEC O26:H11 Growth, and Bacterial Community Patterns in Raw Milk Uncooked Pressed Cheeses

MDPI

Adding massive amounts of lactic starters to raw milk to manage the sanitary risk in the cheese-making process could be detrimental to microbial diversity. Adjusting the amount of the lactic starter used could be a key to manage these adverse impacts. In uncooked pressed cheeses, we investigated the impacts of varying the doses of a lactic starter (the recommended one, 1×, a 0.1× lower and a 2× higher) on acidification, growth of Staphylococcus aureus SA15 and Shiga-toxin-producing Escherichia coli (STEC) O26:H11 F43368, as well as on the bacterial community patterns. We observed a delayed acidification and an increase in the levels of pathogens with the 0.1× dose. This dose was associated with increased richness and evenness of cheese bacterial community and higher relative abundance of potential opportunistic bacteria or desirable species involved in cheese production. No effect of the increased lactic starter dose was observed. Given that sanitary criteria were paramount to our study, the increase in the pathogen levels observed at the 0.1× dose justified proscribing such a reduction in the tested cheese-making process. Despite this, the effects of adjusting the lactic starter dose on the balance of microbial populations of potential interest for cheese production deserve an in-depth evaluation. View Full-Text

Research – Presumptive probiotic bacteria from traditionally fermented African food challenge the adhesion of enteroaggregative E. coli

Wiley Online

E.coli

Colonization of intestinal tract with the potential to exclude, displace, and inhibit enteric pathogens is principally dependent on the adhesion ability of probiotics. Therefore, probiotic efficacy is considered to be mainly determined by their adhesion ability. The current study reports the antagonistic effect of four lactic acid bacteria (LAB) on the adhesion profile of four diarrhoeagenic and one non‐diarrhoeagenic enteroaggregative Escherichia coli (EAEC). All the bacterial strains investigated adhered to the Caco‐2 cells. All the LAB tested competitively excluded, displaced, and inhibited at least three (non‐) diarrhoeagenic EAEC strains from adhesion (p < 0.05). In all, Lactobacillus plantarum, FS2 exhibited the strongest adhesion to the Caco‐2 cells, competitive exclusion (CE), displacement, and inhibition against most of the EAEC strains. Additionally, the competence to exclude, displace, and inhibit the EAEC from adhesion depended on both the pathogens and the LAB strains tested; signifying the participation of several mechanisms. Contrary to all the EAEC strains, gastro‐intestinal stress factors such as low pH (2.5) had no effect on the adhesion of the LAB. Unlike the gastro‐intestinal acidic conditions, bile salt conditioning (at pH 6.5) had no effect on the adhesion of both EAEC and LAB. In conclusion, all the LAB tested showed specific anti‐adherence effects including CE, displacement, and inhibition against the selected EAEC. The results indicate that all the LAB, particularly, the L. plantarum, FS2 had a good ability for exerting antagonistic effects against the selected EAEC for the prevention of gastrointestinal infection.

WHO – DRAFT WHO GLOBAL STRATEGY FOR FOOD SAFETY 2022-2030

WHO

Introduction

Why an updated global food safety strategy?

Safe food is a primary determinant of human health. It is a basic human right to have access to safe and healthy food. In seeking to guarantee this right, governments must ensure that available food meets safety standards.

This task is not easy as the world is now more interconnected, and food systems are changing faster than ever. Foods are produced, managed, delivered and even consumed in ways that could not have been anticipated two decades ago.

These factors call for a fresh global approach to improve food safety that aims to strengthen national food safety systems while improving international and national collaboration.

While recognizing that food safety is a shared responsibility among multiple stakeholders, countries must show leadership in adopting and implementing food safety policies which ensure that each stakeholder knows–and correctly plays –their part.

However, access to sufficient, safe, and wholesome food for all remains an elusive goal. Economic disparities within and across countries, including marked differences in the strength of national food safety systems and complex dynamics that operate within food systems, have significantly slowed progress towards achieving this goal.

USA – Outbreak Investigation of Listeria monocytogenes – Hispanic-style Fresh and Soft Cheeses (February 2021)

FDA

The FDA, along with CDC and state and local partners, investigated a multistate outbreak of Listeria monocytogenes infections linked to queso fresco cheeses made by El Abuelito Cheese, Inc. On 5/14/2021, the CDC announced that this outbreak is over.

Recommendation

Recalled Queso Fresco, Quesillo (Oaxaca, string cheese), or Requeson (ricotta) cheeses are past shelf life and should no longer be available.

FDA recommends that anyone who received recalled products use extra vigilance in cleaning and sanitizing any surfaces and containers that may have come in contact with these products to reduce the risk of cross-contamination. Listeria can survive in refrigerated temperatures and can easily spread to other foods and surfaces.

People who are pregnant, are age 65 or over, or have a weakened immune system should not eat any soft cheeses unless they are made with pasteurized milk. Consumers at higher risk for Listeria illness should be aware that although pasteurization of milk kills Listeria, soft cheeses made from pasteurized milk can still become contaminated and have caused Listeria outbreaks, including this one.

USA – TECHNICAL REPORT:FDA REPORT ON THE OCCURRENCE OF FOODBORNE ILLNESS RISK FACTORS IN RETAIL FOOD STORE DELI DEPARTMENTS2015-2016MAY 2021

FDA

This report includes the background, design, and results of data collection on the occurrence of foodborne illness risk factors in the United States in retail food store deli departments (hereafter referred to as delis) during 2015-2016. It is a baseline report representing the first data collection period of the FDA’s current 10-year study on trends in the occurrence of foodborne illness risk factors and food safety behaviors/practices in food service facilities. Data from the 2015-2016 collection will be used as a baseline to assess trends in the occurrence of risk factors in future data collections. Of the foodborne illness risk factors investigated in this study, inadequate cooking was best controlled. The two most commonly occurring out-of-compliance risk factors were improper holding time/temperature and poor personal hygiene. Food Safety Management Systems (FSMS) were the strongest predictor of the compliance status of data items. Establishments with well-developed FSMS had significantly fewer out-of-compliance food safety behaviors/practices than did those with “less developed” food safety management systems. Neither the presence of a Certified Food Protection Manager (CFPM) nor the multiple-unit status of establishments were significant predictors of having out-of-compliance data items when all factors studied were taken into account. These findings suggest that well-developed and documented FSMS are a useful tool in reducing the occurrence of foodborne illness risk factors.
