On September 14, 2006 the U.S. Food and Drug Administration (FDA) released a “Warning on Serious
Food borne E. coli O157:H7 Outbreak.” The FDA announced that a multi-state outbreak of E. coli O157:H7 that “may be associated with the consumption of produce.” The FDA stated that, “preliminary epidemiological evidence suggest that bagged fresh spinach may be a possible cause of this outbreak.” As of that date, 50 cases of illness had been reported to the Centers for Disease Control and Prevention (CDC), including 8 cases of HUS and 1 death. The impacted states were noted to include Connecticut, Idaho, Indiana, Michigan, New Mexico, Oregon, Utah and Wisconsin.
In the ensuing three weeks, the
FDA issued numerous press releases reporting on the expanding size and scope of the outbreak. The releases also followed the FDA as it zeroed in on its conclusion that the source of the outbreak was Dole bagged spinach.
On September 15, the FDA issues an additional press release advising, “people not eat fresh spinach or fresh spinach containing products.” The FDA indicated that 94 cases of illness, including 14 cases of HUS and 1 death were now associated with the outbreak. The outbreak was identified as affecting 20 states. Concurrently, Natural Selection Foods (NSF) recalled all of its products containing spinach with “use by” dates from August 17, 2006 through October 1, 2006. The recall included Dole brand spinach.
New press releases on September 16, 17, 18, 19 updated the number of illness to 131, including 20 cases of HUS, 66 hospitalizations, and 1 death in 21 states. By this time there were two recalls, including the one initiated by NSF.
The FDA and
CDC, in conjunction with local and state health agencies across the country continued its investigation of the outbreak. On September 20, the FDA reported that the New Mexico Department of Health had “linked a sample from a package of spinach with the outbreak strain of E. coli O157:H7.” The package had contained spinach eaten by a New Mexico outbreak member before becoming ill. The package of spinach that tested positive was “Dole Baby Spinach, Best if Used by August 30.” At the same time, the FDA indicated that it had no evidence that frozen spinach, canned spinach, or spinach in pre-made meals manufactured by food companies were affected, and announced those products safe to eat.
The following day, September 21, the FDA confirmed that the genetic testing done on the Dole bag in New Mexico was a match to the strain of E. coli O157 that had sickened what was then a reported 157 people across the country. The list of affected states had grown to 23.
On September 22, the FDA announced that the implicated spinach had all been grown in one or more of three counties in California, Monterey, San Benito, and Santa Clara. The FDA was working with the CDC to further narrow the area of implicated spinach. The outbreak had grown to 166 illnesses in 25 states.
On September 24, the FDA announced further laboratory confirmation of the outbreak. The Utah Department of Health and the Salt Lake Valley Health Department reported that another bag of Dole baby spinach had tested positive for the outbreak strain of E. coli O157:H7. The list of victims on that date included 173 illnesses, 27 cases of
HUS, 92 hospitalizations and 1 death.
On September 29, the FDA announced its preliminary conclusions regarding the outbreak. The FDA announced that:
…all spinach implicated in the current outbreak has traced back to Natural Selection Foods LLC of San Juan Bautista, California. This determination is based on epidemiological and laboratory evidence obtained by multiple states and coordinated by the [CDC].
The FDA also updated the number of illnesses, and reported on numerous new laboratory findings of the outbreak strain of E. coli O157:H7 in bags of Dole baby spinach.
Over the ensuing 10 days, the FDA continued to update the number of illnesses, as well as the growing number of Dole baby spinach bags that had tested positive for the outbreak strain of E. coli O157:H7. On October 5, the U.S. Department of Justice issued the following press release:
The US Attorney's Office for the Northern District of California announced that agents of the FBI and FDA Office of Criminal Investigations executed two search warrants today on Growers Express in Salinas, CA, and Natural Selection Foods in San Juan Batista, CA, in connection with the September 2006 outbreak of E. coli 0157:H7 that the FDA has traced to spinach grown in the Salinas area…United States Attorney Kevin V. Ryan stated that "I want to reassure the public that there is no indication in this investigation that leaf spinach was deliberately or intentionally contaminated. We are investigating allegations that certain spinach growers and distributors may not have taken all necessary or appropriate steps to ensure that their spinach was safe before it was placed into interstate commerce…
On October 12, the FDA reported that test results from the investigation of the outbreak indicated that environmental samples taken from the implicated fields on four ranches had tested positive for the outbreak strain of E. coli O157:H7. According to the FDA, the four fields were located in Monterey and San Benito counties.
The most recent tally from the FDA included 204 illnesses due to E. coli O157:H7 reported the CDC. This number included 31 cases of HUS, 102 hospitalizations, and 3 deaths. The FDA maintained its conclusion that all the implicated spinach was traced back to NSF. The FDA also reported 13 “confirmed product samples that contain the E. coli O157:H7 outbreak strain.” Each of these products was bagged Dole baby spinach.
