In an ongoing effort to understand sources of foodborne illness in the United States, the Interagency Food Safety Analytics Collaboration (IFSAC) collects and analyzes outbreak data to produce an annual report with estimates of foods responsible for foodborne illnesses caused by pathogens. The report estimates the degree to which four pathogens – Salmonella, E. coli O157, Listeria monocytogenes, and Campylobacter – and specific foods and food categories are responsible for foodborne illnesses.
The Centers for Disease Control and Prevention (CDC) estimates that, together, these four pathogens cause 1.9 million foodborne illnesses in the United States each year. The newest report (PDF), entitled “Foodborne illness source attribution estimates for 2017 for Salmonella, Escherichia coli O157, Listeria monocytogenes, and Campylobacter using multi-year outbreak surveillance data, United States,” can be found on the IFSAC website.
The updated estimates, combined with other data, may help shape agency priorities and inform the creation of targeted interventions that can help to reduce foodborne illnesses caused by these pathogens. As more data become available and methods evolve, attribution estimates may improve. These estimates are intended to inform and engage stakeholders and to improve federal agencies’ abilities to assess whether prevention measures are working.

Emily Olle of 7 News reports 15 people have been struck with salmonella following a national recall of frozen meals sold at Coles and IGA supermarkets.
Core Powerfoods issued a recall of their frozen meals, including the 310g or 350g Going Nuts, Deep South Chilli, Muay Thai Meatballs, Holy Meatballs, Naked
SA Health’s Dr Fay Jenkins said South Australians should throw out their products, with three South Australians among those affected.
“There have been 15 cases of Salmonella Weltevreden in people who ate these products nationally and we are urging anyone with these meals in their freezers to throw them away or return them to where they bought them,” Jenkins said.
“While this particular type of Salmonella is unusual, any kind of Salmonella poses serious health risks and symptoms of infection can begin anywhere between six and 72 hours after exposure and last for three to seven days.”
Salmonella outbreaks in childcare facilities are relatively rare, most often occurring secondary to contaminated food products or poor infection control practices. We report an outbreak of Salmonella Saintpaul at a pre-school facility in Ayrshire, Scotland with atypical clinical and epidemiological features.

Following notification of the initial two cases, the multi-disciplinary Incident Management Team initiated enhanced active case finding and two environmental inspections of the site, including food preparation areas. Parent and staff interviews were conducted by the Public Health department covering attendance, symptomatology and risk factors for all probable and confirmed cases. Microbiological testing of stool samples and the facility water tank was conducted. Whole Genome Sequencing (WGS) was performed for positive stool samples at the national reference laboratory. Infection control measures were introduced iteratively due to the atypical progression of the outbreak.
There were 15 confirmed cases and 3 children admitted to hospital during the outbreak. However, 35.7% of cases reported extremely mild symptoms. The attack rate was 15.2%, and age of affected children ranged from 18 to 58 months (mean 35 months). All cases were the same Multilocus Sequence Type (MLST50). Epidemiological investigation strongly suggested person-to-person spread within the facility. Existing infection control practices were found to be of a high standard, but introduction of additional evidence-based control measures was inadequate in halting transmission. Facility staff reported concerns about lack of parental disclosure of gastrointestinal symptoms, particularly where these were mild, with 50.0% of cases having attended while symptomatic against public health advice. Voluntary two-week closure of the facility was implemented to halt transmission, following which there were no new cases. WGS results were unavailable until after the decision was taken to close the facility.
This is the first reported instance of a Salmonella Saintpaul outbreak at a childcare facility, or where person-to-person transmission is indicated. Clinicians should consider the influence of parental under-reporting on gastrointestinal outbreaks in childcare settings, particularly where perceived severity is low and financial or social pressures to attend work may reduce compliance. WGS cannot yet replace conventional microbiological techniques during short, localised outbreaks due to delays receiving results.
Emma Broadhurst was six months pregnant when she flew out to Turkey with friends for a 7-night stay at the Crystal Sunset Luxury Resort and Spa, east of the city of Antayla, at the start of September.
But, according to Andy Rudd of The Mirror, within days of arriving she fell unwell suffering from chronic diarrhea and became dehydrated and lost weight.
Just over 24 hours later her best friend’s seven-year-old son, Kailan, also fell ill with diarrhea and on their return to the UK his mum, Emma McComb, fell ill and Kailan was left ‘screaming in agony’ and projectile vomiting.
All three, who shared a room while on holiday, were then diagnosed with salmonella poisoning after stool samples were sent for testing by their local GP, claims Emma.
The friends stayed in the same hotel where two-year-old Allie Birchall and her family holidayed before little Allie was taken ill before passing away having contracted E. coli.
All members of her family, from Wigan, Greater Manchester, suffered from gastric symptoms including stomach cramps and diarrhoea during their 10-day stay with Jet 2.
Allie’s condition became so severe she was rushed to hospital after the family returned to the UK.
Her parents had to make the heartbreaking decision to switch off her life support on August 3.
Outbreak News Today reports Swedish health authorities, or Folkhalsomyndigheten are reporting 17 additional Salmonella Typhimurium cases in the current outbreak, bringing the total outbreak cases to 71 since August.
The Swedish National Food Agency and the Public Health Agency continue to investigate the outbreak to identify the source of the infection. The investigation shows that small tomatoes are the likely source of the outbreak. The tomatoes are no longer left in grocery stores, the outbreak has subsided and the risk of being infected is very small.
In interviews, 12 (71%) of 17 ill people reported contact with a turtle.
This investigation is ongoing and CDC will provide updates when more information is available.
Turtles can carry Salmonella germs in their droppings while appearing healthy and clean. These germs can easily spread to their bodies, tank water, and habitats. People can get sick after they touch a turtle or anything in their habitats.
Always wash hands thoroughly with soap and water right after touching, feeding, or caring for a turtle or cleaning its habitat.
Adults should supervise handwashing for young children.
Don’t kiss or snuggle turtles, because this can spread Salmonella germs to your face and mouth and make you sick.
Don’t let turtles roam freely in areas where food is prepared or stored, such as kitchens.
Clean habitats, toys, and pet supplies outside the house when possible.
Avoid cleaning these items in the kitchen or any other location where food is prepared, served, or stored.
Pick the right pet for your family.
CDC and public health officials in several states are investigating a multistate outbreak of human Salmonella Oranienburg infections linked to contact with pet turtles.
Public health investigators are using the PulseNet system to identify illnesses that may be part of this outbreak. PulseNet is the national subtyping network of public health and food regulatory agency laboratories coordinated by CDC. DNA fingerprinting is performed on Salmonella bacteria isolated from ill people by using a standardized laboratory and data analysis method called whole genome sequencing (WGS). CDC PulseNet manages a national database of these sequences that are used to identify possible outbreaks. WGS gives investigators detailed information about the bacteria causing illness. In this investigation, WGS showed that bacteria isolated from ill people were closely related genetically. This means that people in this outbreak are more likely to share a common source of infection.
Ill people reported contact with red-eared sliders and other turtles that were larger than four inches in length. Previous Salmonella outbreaks have been linked to turtles with a shell length less than four inches. Due to the amount of Salmonella illnesses related to these small turtles, the U.S. Food and Drug Administration banned the sale and distributionexternal icon of turtles with shells less than four inches long as pets.
Regardless of where turtles are purchased or their size, turtles can carry Salmonella germs that can make people sick. Pet owners should always follow steps to stay healthy around their pet.
This investigation is ongoing, and CDC will provide updates when more information becomes available.
Cal Rolston of NCTY News reports 168 children were sent to hospital with possible Salmonella food poisoning in Dongguan, Guangdong Province prompting health authorities to shut down a kindergarten on Monday for two days.
One hundred and three people, including 99 children, remained in hospitals in the city and neighboring Shenzhen, according to statements released by the Dongguan Health Bureau.
Nobody died or was critically ill as of Sunday midnight, the bureau said.
SVT reports people have been sick with diarrhea between August 29 and September 14 with Salmonella Typhimurium. Anders Enocksson, infection prevention consultant at Region Halland.
In all, 11 counties are affected. Most cases are in Halland together with Dalarna, Jönköping and Västra Götaland, which P4 Halland was the first to tell . The infected are in all age groups, but just over half are 60 years or older. There are slightly more women than men.
The source of infection is not yet known, but there is suspicion of tomatoes, and cherry tomatoes. It is unclear where they come from. The investigation is allowed to show if it is correct, says Anders Enocksson.
To date, 36 cases from 10 counties have been linked with whole-genome sequencing. Most cases have been reported from Västra Götaland, Jönköping, Halland and Dalarna. Ill persons are found in all age groups, both among children and the elderly, and slightly more women (22) than men (14) have become sick.
The Swedish National Food Agency and the Public Health Authority together are investigating the outbreak to identify the source of the infection that is suspected to be a food that has been widely distributed in Sweden.
