At the crossroad between Europe, Asia, and Africa, Bulgaria is part of the Mediterranean – Black Sea Flyway (MBSF) used by millions of migratory birds. In this study, bird species migrating through Bulgaria were investigated as carriers of zoonotic pathogens. In total, 706 birds belonging to 46 species were checked for the presence of various bacterial pathogens (Campylobacter, Yersinia, Salmonella, Listeria, Escherichia coli, Staphylococcus aureus, Francisella tularensis, Coxiella burnetii, Borrelia burgdorferi, and Brucella spp.). From 673 birds we investigated fecal samples, from the remaining 33, blood samples. We detected Campylobacter 16S rDNA gene in 1.3% of birds, but none were of pathogenic Campylobacter jejuni and Campylobacter coli species. Escherichia coli 16S rDNA gene was found in 8.8% of the birds. Out of 34 birds that transported Yersinia enterocolitica strains (5.05%), only 1 carried a pathogenic isolate. Three birds (0.4%) were carriers of nonpathogenic Salmonella strains. Four avian samples (0.6%) were positive for Listeria monocytogenes and 1 (0.15%) was positive for Brucella spp. None of the birds tested carried the tick-borne pathogens C. burnetii or B. burgdorferi sensu lato. Antibiotic-resistant strains were detected, suggesting that migratory birds could be reservoirs and spreaders of bacterial pathogens as well as antibiotic resistance genes.

Norway – Yersinia enterocolitica outbreak sickens 18 in Norway

Posted on July 9, 2018 by | Leave a comment

Outbreak News Today 

 

The Norway Institute of Public Health reports investigating an outbreak of gastrointestinal bacteria, Yersinia enterocolitica O:9. To date, 18 people from several counties have been diagnosed with the infection.

Health and Food Safety officials are are trying to determine if there is a common source of infection. Interviews are conducted with the patients, and samples from the homes are taken to find the source of infection, if possible.

“Investigations can be complicated and take time, and in many cases you will not be able to find the source of infection or to clarify if there is a common source”, says Solveig Jore Senior Adviser.

Research – MMWR Examines Trends of Foodborne Illness Outbreaks From 2006 to 2017

Posted on March 30, 2018 by | Leave a comment

Food Poisoning Bulletin 

 

The CDC is examining trends of foodborne illness outbreaks for 2017 and describes changes in incidence since 2006 in its Morbidity and Mortality Weekly Report (MMWR) for March 23, 2018. Foodborne illness is a substantial health burden in the Untied States. In 2017, there were 24,484 infections, 5,677 hospitalizations, and 122 deaths attributed to food borne illness.

Despite ongoing food safety measures in the United States, foodborne illness continues to be a substantial health burden. The 10 U.S. sites of the Foodborne Diseases Active Surveillance Network (FoodNet)* monitor cases of laboratory-diagnosed infections caused by nine pathogens transmitted commonly through food. This report summarizes preliminary 2017 data and describes changes in incidence since 2006. In 2017, FoodNet reported 24,484 infections, 5,677 hospitalizations, and 122 deaths. Compared with 2014–2016, the 2017 incidence of infections with Campylobacter, Listeria, non-O157 Shiga toxin–producing Escherichia coli (STEC), Yersinia, Vibrio, and Cyclospora increased. The increased incidences of pathogens for which testing was previously limited might have resulted from the increased use and sensitivity of culture-independent diagnostic tests (CIDTs), which can improve incidence estimates (1). Compared with 2006–2008, the 2017 incidence of infections with Salmonella serotypes Typhimurium and Heidelberg decreased, and the incidence of serotypes Javiana, Infantis, and Thompson increased. New regulatory requirements that include enhanced testing of poultry products for Salmonella† might have contributed to the decreases. The incidence of STEC O157 infections during 2017 also decreased compared with 2006–2008, which parallels reductions in isolations from ground beef.§ The declines in two Salmonella serotypes and STEC O157 infections provide supportive evidence that targeted control measures are effective. The marked increases in infections caused by some Salmonella serotypes provide an opportunity to investigate food and nonfood sources of infection and to design specific interventions.

Research – Microbiological Quality of Fresh-Cut Carrots and Process Waters

Posted on July 10, 2013 by | Leave a comment

Ingenta ConnectSalmonella

Fresh vegetables may be contaminated by pathogens in different ways after harvest. Pathogenic microorganisms associated with fresh vegetables can cause severe outbreaks of foodborne disease. We discuss here the results of microbiological analysis of carrot samples, as well as of washing, processing, and wastewater samples. Washed, unpeeled carrots generally contained the highest aerobic plate counts (mean, 5.5 log CFU/g). Escherichia coli was not detected in any carrot or water sample examined. The amounts of coliform bacteria and enterobacteria were higher in carrot samples taken from the first steps in the processing line than in samples taken in later phases of the process. Yersinia pseudotuberculosis was not detected in any of the samples by the cultivation method; however, nonpathogenic Yersinia enterocolitica was detected from most carrot samples and almost all washing water and wastewater samples but only from 2 of 10 process water samples. Using a more-sensitive real-time PCR method, pathogenic Y. enterocolitica was found from several carrot samples, and when these positive samples were cultivated, no pathogenic Y. enterocolitica strains were detected.

USA Research -CDC – Report on Levels of Yersinia in Pork

Posted on November 28, 2012 by | Leave a comment

Food Safety News

In a new study of raw pork chops and ground pork, Consumer Reports found 69 percent of samples were contaminated with Yersinia enterocolitica, according to a report published by the group today.

A lesser-known foodborne pathogen, Yersinia enterocolitica can cause fever, abdominal pain and diarrhea, lasting one to three weeks, according to the Centers for Disease Control and Prevention. There is approximately one confirmed infection per 100,000 people reported each year, but since these cases are severely under-reported, CDC estimates there are actually around 100,000 infections in the United States annually.
