Research – Helicobacter pullorum Isolated from Fresh Chicken Meat: Antibiotic Resistance and Genomic Traits of an Emerging Foodborne Pathogen

American Society of Microbiology

Meat and meat products are important sources of human intestinal infections. We report the isolation of Helicobacter pullorum strains from chicken meat. Bacteria were isolated from 4 of the 17 analyzed fresh chicken meat samples, using a membrane filter method. MIC determination revealed that the four strains showed acquired resistance to ciprofloxacin; one was also resistant to erythromycin, and another one was resistant to tetracycline. Whole-genome sequencing of the four strains and comparative genomics revealed important genetic traits within the H. pullorum species, such as 18 highly polymorphic genes (including a putative new cytotoxin gene), plasmids, prophages, and a complete type VI secretion system (T6SS). The T6SS was found in three out of the four isolates, suggesting that it may play a role in H. pullorum pathogenicity and diversity. This study suggests that the emerging pathogen H. pullorum can be transmitted to humans by chicken meat consumption/contact and constitutes an important contribution toward a better knowledge of the genetic diversity within the H. pullorum species. In addition, some genetic traits found in the four strains provide relevant clues to how this species may promote adaptation and virulence.

USA – Shigella at Day Care Center and Schools

Food Poisoning Bulletin 220px-Shigella_stool

Daycare centers and schools in Lubbock, Texas have reported an increase in the number of reported cases of shigellosis. Typically, only a few cases of the highly contagious bacterial infection are reported each month, but since September 1, 71 conformed cases have been reported

Australia -Bean sprouts – have there ever problems with contaminated bean sprouts in Australia?

Food Safety Council

Outbreaks of food-borne illness both in Australia and overseas have been associated with eating seed sprouts. Most seed sprouts are consumed raw, therefore do not receive any form of heat treatment prior to consumption which would inactivate pathogens (if present). A 2005 Salmonella outbreak in WA of 125 cases was linked to alfalfa sprouts  and a 2006 Salmonella outbreak of 15 cases in Victoria was linked to alfalfa sprouts.

USA – Chipotle Restaurants – E.coli Outbreak – 19 Cases Confirmed

Food Poisoning Journal

AP now reports that Washington and Oregon Health officials are investigating an E. coli outbreak linked to six Chipotle restaurants in Washington state and Oregon, health officials said Saturday. Three people in the Portland area and at least 19 people in Washington have become sick after eating at the Mexican food chain since October 14.

The Skagit Valley Herald reports that the Skagit County Department of Public Health announced Friday that it has closed Chipotle Mexican Grill in Burlington pending an investigation of several E. coli infections among recent diners.

UN blamed for food poisoning outbreak after “mouldy” biscuits in aid convoy delivered to Syria

Mirror Mould

Hundreds of boxes of “mouldy” biscuits sent to Syria by the United Nations have caused widespread food poisoning , it is claimed.

The high-energy snacks were past their sell-by date when they were given out as humanitarian aid, a watchdog said today.

A Legionnaires’ Disease outbreak at St. Joseph’s Hospital Health Center in Syracuse New York has sickened at least two people. While the President and CEO of that facility, Kathryn Ruscitto, has issued statements about the bacteria being found in the hospital’s water supply, no official reports have been released acknowledging the outbreak except indirectly

All American Meats, Inc., an Omaha, Neb. establishment, is recalling approximately 167,427 pounds of ground beef products that may be adulterated with E. coli O157:H7, the U.S. Department of Agriculture’s Food Safety and Inspection Service (FSIS) announced today.

Research – Toxoplasma gondii in Wild Red Squirrels, the Netherlands, 2014

CDC Toxoplasma

In September 2014, the number of dead squirrels reported to the Dutch Wildlife Health Centre and the Dutch Mammal Society increased suddenly. The red squirrel (Sciurus vulgaris) is the only species of squirrel endemic to the Netherlands. Members of the public claimed that squirrels were “dropping dead from trees.” Subsequently, the public was encouraged to report and submit dead squirrels. A total of 187 animals were reported through October 2014, of which 37 were submitted for necropsy. Necropsy included macroscopic examination; cytologic analysis of liver, spleen, lungs, and intestinal contents stained with hemacolor (Merck, Darmstadt, Germany); and histologic examination of samples of various organs fixed in formalin, embedded in paraffin, cut into 4-μm sections, and stained with hematoxylin and eosin.

Research – Cyclospora infection linked to travel to Mexico, June to September 2015

Eurosurveillance 220px-Cyclospora_cayetanensis_stained

Cyclospora cayetanensis was identified in 176 returned travellers from the Riviera Maya region of Mexico between 1 June and 22 September 2015; 79 in the United Kingdom (UK) and 97 in Canada. UK cases completed a food exposure questionnaire. This increase in reported Cyclospora cases highlights risks of gastrointestinal infections through travelling, limitations in Cyclospora surveillance and the need for improved hygiene in the production of food consumed in holiday resorts.


On 14 July 2015, Health Protection Scotland (HPS) identified an unusual increase in Cyclospora infections in travellers to Mexico. National and international partners were informed and upon further investigation, a total of 176 cases have been identified in England, Scotland, Wales and Canada. An outbreak control team managed the investigation in the United Kingdom (UK). UK patients were interviewed about travel history, food consumption, clinical symptoms and demography using a questionnaire. The majority of cases had travelled to the Riviera Maya region of Mexico.

Investigation of UK cases

Cyclospora cases were identified in primary clinical diagnostic and commercial laboratories by microscopy or molecular testing. Cases were confirmed in reference laboratories using microscopic methods (e.g. examination of a wet preparation by bright field microscopy and, if structures resembling Cyclospora were observed, viewing under UV light for autofluorescence). In addition, smears were permanently stained using modified Ziehl Neelsen and examined.

In the UK, probable cases were defined as individuals with onset of gastrointestinal (GI) symptoms or a specimen date on or after 1 June 2015, travel to Mexico in the previous 14 days and C. cayetanensis oocysts identified in stool specimens by a local diagnostic laboratory. Confirmed UK cases were probable cases confirmed microscopically by national reference laboratories. Cases without either local or national reference laboratory confirmation were excluded from this analysis. No cases associated with travel to Mexico were identified in the UK in 2015 before 1 June.

Outbreak description

Between 1 June and 22 September 2015, 79 probable or confirmed case-patients (hereafter called cases) were reported in England (n = 55), Scotland (n = 21) and Wales (n = 3). No further cases linked to Mexico have been identified in the period since that date (as at 28 October 2015). Symptom onset dates were available for 62 confirmed or probable cases and ranged from 8 June to 19 August 2015 (Figure 1). Travel information was available for 60 cases; the earliest departure date from the UK to Mexico was 22 May and the latest date of return was 30 August 2015. The median age of cases was 44 years (range: 15–66) with 46 of 79 cases 40 years and older; 43 of 79 were female. Only 43 of the 79 cases diagnosed in local laboratories were confirmed by a reference laboratory.
