Not to be confused with the Seven Deadly Sins: pride, greed, lust, envy, gluttony, wrath and sloth, although, perhaps some of these outbreaks were sinful. I had the honor to represent many of the ill and the families of those who died.
Jack-in-the- Box E. coli Outbreak – 1992 – 1993
708 ill, 171 hospitalized and 4 dead
An outbreak of E. coli O157:H7 was linked to the consumption of hamburgers from the Jack-in-the-Box Restaurant chain. Cases were reported from the states of Washington (602 cases/144 hospitalizations/3 deaths), Idaho (14 cases/4 hospitalizations/no deaths), California (34 cases/14 hospitalizations/1 death), and Nevada (58 cases/9 hospitalizations/no deaths). A case control study implicated the chain’s hamburgers resulting in a multistate recall of the remaining hamburgers. Only 20 percent of the product remained at the time of the recall; this amounted to 272,672 hamburger patties. Subsequent testing of the hamburger patties showed the presence of E. coli O157:H7. The strain of E. coli O157:H7 found in ill people matched the strain isolated from uncooked hamburger patties. The outbreak illustrated the potential for large, foodborne illness outbreaks associated with restaurant chains receiving shipments of contaminated food. At the time, many clinical laboratories in the United States were not routinely culturing patients’ stool for E. coli O157:H7 by using the correct culture medium. Additionally, many local and state health departments were not actively tracking and investigating E. coli O157:H7 cases.
Chi Chi’s Green Onion Hepatitis A Outbreak – 2003
565 ill, 130 hospitalized and 3 dead
Pennsylvania State health officials first learned of a hepatitis A outbreak when unusually high numbers of hepatitis A cases were reported in late October 2003. All but one of the initial cases had eaten at the Chi Chi’s restaurant at the Beaver Valley Mall, in Monaca, PA. Ultimately, at least 565 cases were confirmed. The victims included at least 13 employees of the Chi Chi’s restaurant, and residents of six other states. Three people died as a consequence of their hepatitis A illnesses. More than 9,000 people who had eaten at the restaurant, or who had been exposed to ill people, were given a post-exposure injection as a prevention against developing hepatitis A. Preliminary analysis of a case-control study indicated fresh, green onions were the probable source of this outbreak. The investigation and tracebacks by the state health department, the CDC, and the FDA, confirmed that the green onions had been grown in Mexico.
238 ill, 103 hospitalized and 5 dead
On Sept. 13, 2006, public health officials in Wisconsin, Oregon and New Mexico noted E. coli O157:H7 infections with matching pulsed-field gel electrophoresis (PFGE) patterns. These illnesses were associated with eating fresh, bagged spinach produced by Dole Brand Natural Selection Foods. By Sept. 26 that year, infections involving the same strain of E. coli O157:H7 had been reported from 26 states with one case in Canada. A voluntary recall was issued by the company on Sept. 15. E. coli O157: H7 was isolated from 13 packages of spinach supplied by patients in 10 states. Eleven of the packages had lot codes consistent with a single manufacturing facility on a particular day. The PFGE pattern of all tested packages matched the PFGE pattern of the outbreak strain. The spinach had been grown in three California counties – Monterey, San Benito and Santa Clara. E. coli O157:H7 was found in environmental samples collected near each of the four fields that provided spinach for the product, as designated by the lot code. However, E. coli O157:H7 isolates associated with only one of the four fields, located on the Paicines Ranch in San Benito County, had a PFGE pattern indistinguishable from the outbreak strain. The PFGE pattern was identified in river water, cattle feces and wild pig feces on the Paicines Ranch, the closest of which was less than one mile from the spinach field.
Peanut Corporation of America Salmonella Outbreak – 2008 – 2009
714 ill, 171 hospitalized and 9 dead
Beginning in November 2008, CDC’s PulseNet staff noted a small and highly dispersed, multistate cluster of Salmonella Typhimurium isolates. The outbreak consisted of two pulsed-field gel electrophoresis (PFGE) defined clusters of illness. Illnesses continued to be revealed through April 2009, when the last CDC report on the outbreak was published. Peanut butter and products containing peanut butted produced at the Peanut Corporation of America plant in Blakely, GA, were implicated. King Nut brand peanut butter was sold to institutional settings. Peanut paste was sold to many food companies for use as an ingredient. Implicated peanut products were sold widely throughout the USA, 23 countries and non-U.S. territories. Criminal sanctions were brought against the owners of PCA.
Jensen Farms Cantaloupe Listeria Outbreak – 2011
147 ill, 143 hospitalized and 33 dead
A multistate outbreak of Listeria monocytogenes involving five distinct strains was associated with consumption of cantaloupe grown at Jensen Farms’ production fields near Granada, CO. A total of 147 ill people were reported to the CDC. Thirty-three people died, and one pregnant woman miscarried. Seven of the illnesses were related to pregnancy – three newborns and four pregnant women. Among 145 ill people with available information, 143 – 99 percent – were hospitalized. Source tracing of the cantaloupes indicated that they came from Jensen Farms, and were marketed as being from the Rocky Ford region. The cantaloupes were shipped from July 29 through Sept. 10, 2011, to at least 24 states, and possibly distributed elsewhere. Laboratory testing by the Colorado Department of Public Health and Environment identified Listeria monocytogenes bacteria on cantaloupes collected from grocery stores and from ill persons’ homes. Laboratory testing by FDA identified Listeria monocytogenes matching outbreak strains in samples from equipment and cantaloupe at the Jensen Farms’ packing facility in Granada, Colorado. Criminal sanctions were brought against the two owners of Jensen Farms.
Bidart Caramel Apple Listeria Outbreak
35 ill, 34 hospitalized and 7 deaths
On December 19, 2014, the CDC announced a multistate outbreak of Listeria monocytogenes linked to commercially produced, prepackaged caramel apples. A total of 35 people infected with the outbreak strains of Listeria monocytogenes were reported from 12 states. Of these, 34 were hospitalized. Listeriosis contributed to at least 3 of the 7 deaths reported. Eleven illnesses were pregnancy-related with one illness resulting in a fetal loss. here invasive illnesses were among otherwise healthy children aged 5-15 years. Twenty-eight (905) of the 31 ill persons interviewed reported eating commercially produced, prepackaged caramel apples before becoming ill. The Public Health Agency of Canada identified one case of listeriosis that was genetically related to the US outbreak. The investigation was assigned Cluster ID #1411MNGX6-1. On December 24, 2014, Happy Apples issued a voluntary recall of Happy Apple brand caramel apples with best use by date between August 25th and November 23rd, 2014 due to a connection between the apples and outbreak associated cases. California Snack Foods brand caramel apples issued a similar recall on December 27th. Both companies used apples supplied by Bidart Brothers. On December 29 Merb’s Candies recalled Bionic Apples and Double Dipped Apples. On January 6, 2105 Bidart Bros. of Bakersfield, California recalled Granny Smith and Gala apples because environmental testing revealed contamination with Listeria monocytogenes at the firm’s apple-packing facility. On January 8, 2015 FDA laboratory analyses using PFGE showed that environmental Listeria isolates from the Bidart Bros. facility were indistinguishable from the outbreak strains.
Andrew and Williamson Cucumber Salmonella Outbreak – 2015
907 ill, 204 hospitalized and 6 dead
On September 4, 2015 the CDC announced an outbreak of Salmonella Poona linked to consumption of cucumbers grown in Mexico and imported by Andrew & Williamson Fresh Produce. On March 18, 2016 the outbreak was declared to be over. A total of 907 people infected with the outbreak strains of Salmonella Poona were reported from 40 states. Among people for whom information was available, illnesses started on dates ranging from July 3, 2015 to February 29, 2016. Two hundred four ill people were hospitalized and six deaths were reported. Salmonella infection was not considered to be a contributing factor in two of the 6 deaths. Epidemiologic, laboratory, and traceback investigations identified imported cucumbers from Mexico and distributed by Andrew & Williamson Fresh Produce as the likely source of the infections in this outbreak.
