The five Biggest U.S. Foodborne Illness Outbreaks of 2015

Salmonella caused six out of ten larger outbreaks

5. Shigella from Mariscos San Juan, 194 sickened. The Santa Clara County Public Health Department reported on Nov. 9 that 194 people were sickened with Shigella. Nearly all of the cases reported that they ate at Mariscos San Juan restaurant on Oct. 16 or 17. [News Report]

4. Salmonella Typhimurium from Tarheel Q, 1 death and 280 sickened. Those who fell ill after eating at the Lexington, NC barbeque restaurant came from 16 North Carolina counties and five states. Laboratory testing indicated that the BBQ sample and a sample from a patient who became ill during the beginning of the outbreak were both positive for Salmonella. [News report]

3. Salmonella from the Boise Co-op, 290 sickened. Approximately 290 people were sickened with Salmonella linked to food purchased from the Boise Co-op deli after June 1, 2015. Preliminary test results showed Salmonella growth in raw turkey, tomatoes and onion. [News report]

2. Cyclospora from Mexcan-grown cilantro, 546 sickened.For the third year in a row, Cyclospora-contaminated cilantro grown in Mexico caused a massive outbreak. This year, there were 31 states affected but Texans bore the most with 179 illnesses. The bulk of the illnesses hit at the end of May and throughout June.[CDC outbreak information]

1. Salmonella Poona from Cucumbers, 4 deaths and 838 sickened. This enormous outbreak hospitalized 165 people and four deaths were reported in Arizona, California, Oklahoma and Texas. The outbreak hit California the hardest where 232 people were sickened, but 38 states were affected in total. Investigators identified cucumbers imported from Mexico and distributed by Andrew & Williamson Fresh Produce as a likely source of the infections and there were two recalls of potentially contaminated cucumbers. The number of reported illnesses has declined substantially since the peak of illnesses in August and September, but it hasn’t returned to the number of reported illnesses expected each month (about five). [CDC outbreak information]

t is also interesting to mention the Listeria outbreak connected with Blue Bell Creameries. There were three deaths and 10 illnesses connected to the ice cream and reported as early as 2010. On April 20, 2015, Blue Bell recalled all of its products and began distributing its ice cream again at the end of August. Although the outbreak was fairly small and only one connected illness was reported in 2015, we thought it important to note on this list because of the unusual food product and the national coverage it sparked this year.

New E. coli O26 causing an extensive outbreak

What is the Problem and What is Being Done About It?  
The FDA, CDC, and state and local officials began investigating an outbreak of a different Shiga toxin-producing Escherichia coli O26 (STEC O26) linked to Chipotle Mexican Grill restaurants during December 2015. This outbreak has a rare DNA fingerprint, which is different from the larger, previously reported outbreak.
During the firs outbreak Chipotle Mexican Grill closed 43 restaurants in Washington and Oregon in early November 2015 in response to the initial outbreak. All these restaurants reopened in November 2015. Chipotle Mexican Grill worked in close consultation and collaboration with health officials throughout the investigation to determine whether it was appropriate to reopen these restaurants. Chipotle reports taking the following actions, among others, prior to opening:
Interviews were conducted with five ill people, who all reported eating at Chipotle Mexican Grill restaurants. Whole genome sequencing is being used to see this strain is genetically related to the STEC O26 that caused the larger outbreak. This investigation is ongoing.
The FDA continues to work with Chipotle Mexican Grill restaurants as well as federal, state and local agencies to gather information about the supply chain(s). The FDA will continue to provide updates on the investigation as they become available
The FDA and the Centers for Disease Control and Prevention (CDC) along with state and local officials are investigating two separate outbreaks of E. coli O26 infections that have been linked to food served at Chipotle Mexican Grill restaurants in several states.
Earlier in December 4, 2015, the CDC reports a total of 52 people infected with the outbreak strain of STEC O26 from a total of nine states: California (3), Illinois (1), Maryland (1), Minnesota (2), New York (1), Ohio (3), Oregon (13), Pennsylvania (1), and Washington (27).
There have been 20 reported hospitalizations. There have been no reports of hemolytic uremic syndrome (HUS) and no deaths. Of the three most recent illnesses reported in November, only one ill person, whose illness started on November 10, reported eating at Chipotle Mexican Grill in the week before their illness began. The majority of these cases were reported from Oregon and Washington during October 2015.
To date, whole genome sequencing has been performed on STEC O26 isolates from 21 ill people from California (2), Minnesota (2), New York (1), and Washington (16). All 21 isolates were highly related genetically to one another. On the contrary all microbial testing performed by the company did not yield E. coli (more than 2,500 tests of Chipotle's food, restaurant surfaces, and equipment all showed no E. coli).

FSMA Update: Importing Food under the Foreign Supplier Verification Program

Potential hazards may include any biological, chemical or physical hazards related to the food which are reasonably likely to cause illness or injury
The FSVP rule first looks to the importer. An importer is the U.S. owner or consignee of a food offered for import into the U.S. If the importer is a food manufacturer otherwise subject to the preventive controls rules, no FSVP program is necessary because the hazard is identified and managed under their preventive controls processes. If the importer is not a U.S. manufacturer subject to the preventive controls rules and does not meet one of the other enumerated exceptions, the importer must create and implement an FSVP.An FSVP requires the importer to vouch for the foreign supplier of an article of food. The foreign supplier is generally the foreign entity that manufacturers and processes the food being exported to the United States. If a foreign food passes through an intermediary packer, holder or re-labeler, the original manufacturer is still deemed to be the foreign supplier.
An importer’s FSVP must be a written plan which provides for three separate processes: 1) an evaluation of the potential hazards of the imported food; 2) an evaluation of the performance of the particular foreign supplier; and 3) a plan for the performance of periodic and appropriate supplier verification activities.
Potential hazards may include any biological, chemical or physical hazards related to the food which are reasonably likely to cause illness or injury. If potential hazards are identified, the foreign supplier’s performance in controlling hazards must be evaluated.
Once a foreign supplier is initially evaluated and approved, the supplier’s performance must be verified on a regular basis. If the potential hazard could cause serious adverse health consequences or death, the minimum standard is that a verification audit must be conducted at least annually.
If an importer utilizes several foreign suppliers, a separate FSVP must be developed for each. If an importer obtains more than one food product from any foreign supplier, an FSVP analysis must be performed for each food product, although there may be some overlap making the process easier. The type and method of foreign supplier verification processes is flexible and may include on-site audits, sampling and testing, and/or reviews of the suppliers’ relevant food safety records.
The three processes referred to above in an FSVP may be conducted by the importer itself or the importer may rely upon other specified types of entities so long as the importer itself reviews and assesses the verification records, including the results of supplier verification activities.

WHO Releases First Global Estimates of Foodborne Disease

One in 10 sickened annually around the world each year

About one in every 10 people around the world are affected by foodborne disease each year. Of those 600 million people, 420,000 die as a result.
These numbers are the first global estimates — conservative ones — of foodborne illnesses and were calculated by the World Health Organization (WHO). The comprehensive report, published Thursday, Dec. 3, incorporated 31 foodborne hazards, including bacteria, viruses, parasites, toxins and chemicals.
Diarrheal diseases were responsible for most of the global burden, causing 550 million illnesses and 230,000 deaths, WHO reported. In addition, children younger than 5 years old carried 40 percent of the foodborne disease burden, despite representing only 9 percent of the global population.
31 Foodborne Hazards in WHO Global Estimates
Diarrheal Disease Agents
Campylobacter spp., Cryptosporidium spp., Entamoeba histolytica, Enteropathogenic E. coli (EPEC), Enterotoxigenic E. coli (ETEC), Giardia spp., Norovirus, Salmonella enterica (non-invasive infections) non-typhoidal, Shigella spp., Shiga toxin-producing E. coli (STEC), Vibrio cholerae
Invasive Infectious Disease Agents
Brucella spp., Hepatitis A virus, Listeria spp., Mycobacterium bovis, Salmonella enterica (invasive infections) non-typhoidal, Salmonella enterica Paratyphi A, Salmonella enterica Typhi
Ascaris spp., Echinococcus multilocularis, Echinococcus granulosus, Clonorchis sinensis, Fasciola spp., Intestinal flukes, Opisthorchis spp., Paragonimus spp., Taenia solium, Toxoplasma gondii, Trichinella spp.
Aflatoxin, Cassava cyanide, Dioxin

Multistate Outbreak of Shiga toxin-producing Escherichia coli O26.

Chipotle Mexican Grill restaurants at several states is a likely source of this outbreak.
CDC is only reporting ill people that have been confirmed by PulseNet as being infected with the outbreak strain of Shiga toxin-producing Escherichia coli O26 (STEC O26). Forty-five people infected with the outbreak strain of STEC O26 have been reported from 6 states. The majority of illnesses have been reported from Washington and Oregon. The number of ill people reported from each state is as follows: California (2), Minnesota (2), New York (1), Ohio (1), Oregon (13), and Washington (26).
Among people for whom information is available, illnesses started on dates ranging from October 19, 2015 to November 8, 2015. Ill people range in age from 2 years to 94, with a median age of 22. Fifty-eight percent of ill people are female. Sixteen (36%) people reported being hospitalized. There have been no reports of hemolytic uremic syndrome and no deaths.
CDC and state and local public health partners are continuing laboratory surveillance through PulseNet to identify additional ill persons and to interview them.
Investigation Update: CDC, the U.S. Food and Drug Administration, and public health officials in several states are investigating an outbreak of Shiga toxin-producing Escherichia coli O26 (STEC O26) infections.
The epidemiologic evidence available to investigators at this time suggests that a meal item or ingredient served at Chipotle Mexican Grill restaurants at several states is a likely source of this outbreak. The investigation has not identified what specific food is linked to illness. Chipotle Mexican Grill is assisting public health officials with understanding the distribution of food items served at locations where ill people ate and this work is ongoing.
State and local public health officials are interviewing ill people to obtain information about foods they might have eaten and other exposures in the week before their illness started. Forty-three (96%) of 45 people interviewed reported eating at a Chipotle Mexican Grill restaurant. The investigation is ongoing to identify common meal items or ingredients causing illness.
Investigators are also using whole genome sequencing, an advanced laboratory technique, to get more information about the DNA fingerprint of the STEC O26 bacteria causing illness. To date, whole genome sequencing has been performed on STEC O26 isolates from 9 ill people in Washington and 1 ill person in Minnesota. All 10 isolates were highly related genetically to one another. This provides additional evidence that illnesses outside the Pacific Northwest are related to the illnesses in Oregon and Washington.

FDA Approves GE Salmon, Voluntary Labeling of GE Ingredients

Salmon for human consumption would not have a significant impact on the environment.
The FDA scientists rigorously evaluated extensive data submitted by the manufacturer, AquaBounty Technologies, and other peer-reviewed data, to assess whether AquAdvantage salmon met the criteria for approval established by law; namely, safety and effectiveness. The data demonstrated that the inserted genes remained stable over several generations of fish, that food from the GE salmon is safe to eat by humans and animals that the genetic engineering is safe for the fish, and the salmon meets the sponsor’s claim about faster growth.
In addition, FDA assessed the environmental impacts of approving this application and found that the approval would not have a significant impact on the environment of the United States. That is because the multiple containment measures the company will use in the land-based facilities in Panama and Canada make it extremely unlikely that the fish could escape and establish themselves in the wild.
The agency had made a preliminary finding in December 2012 that approving the AquAdvantage Salmon for human consumption would not have a significant impact on the environment if, as the company plans, it is raised in tanks away from the ocean to limit the impact on wild salmon stocks.
FDA has specified that the GE salmon only be raised in two places, one on Vancouver Island, Canada, and the other in Panama, where Aqua Bounty was fined by the government last year for reportedly not having the proper permits and for repeatedly violating regulations.
Alison Van Eenennaam, Ph.D., a specialist in animal genomics and biotechnology at the University of California, Davis, participated in FDA’s scientific review.
“Basically, nothing in the data suggested that these fish were in any way unsafe or different to the farm-raised salmon,” she said.
AquaBounty’s GE salmon contains a growth gene from the Chinook salmon, which the company says could allow its product to grow to market size in half the time of a conventional Atlantic salmon. Because it involves a recombinant DNA (rDNA) construct introduced into the animal, the GE salmon meets FDA’s definition of a drug.
The company stated Thursday that the FDA approval could mean an “economically viable domestic aquaculture industry while providing consumers a fresh and delicious product,” adding that more than 90 percent of the seafood, and more than 95 percent of the Atlantic salmon, consumed in the U.S. today is imported.
