Authorities in Finland are investigating a Listeria outbreak that has affected eight people.

All patients have been hospitalized but no deaths have been recorded. The age range of those sick is 60 to 93 years old, five are female and they live in different parts of the country.

Ruska Rimhanen-Finne, a veterinary epidemiologist at the National Institute for Health and Welfare (THL), said all illnesses occurred within a month in May and June.

“At the moment, we have several listeriosis clusters under investigation, but the others are long-term clusters with cases within several years,” she told Food Safety News

Whole genome sequencing offers new possibilities for foodborne outbreak detection and investigation, source attribution and hazard identification, according to an EFSA panel.

The scientific opinion by the panel on Biological Hazards covers use of whole genome sequencing (WGS) and metagenomics for outbreak investigation, source attribution and risk assessment of foodborne pathogens. Cost/benefit analyses and technical recommendations on use of WGS and metagenomics were not looked at.

A number of recommendations were made by European Food Safety Authority (EFSA) panel such as standardization and quality control parameters should be internationally agreed and validated to provide evidence that methods are repeatable, reproducible

A review has backed the belief that poultry and ruminants are the main sources of Campylobacter infections.

The work found more than half of human campylobacteriosis cases were attributed to poultry. Ruminants such as cattle or sheep were also implicated in a substantial proportion of infections.

Campylobacter is one of the top causes of acute bacterial gastroenteritis in high, low, and middle income countries. The number of confirmed cases has continued to increase across the European Union from 214,000 in 2013 to 246,000 in 2016 and 2017.
