Status

On October 4, 2006, U.S. Attorney Kevin V. Ryan of the Northern District of California issued a statement on the execution of two search warrants on Growers Express in Salinas, California, and Natural Selection Foods in San Bautista, California, in connection with the outbreak. The statement is available online at http://www.usdoj.gov/usao/can/press/2006/2006_10_04_spinachsearches.press.html.

FDA, the State of California, the Centers for Disease Control and Prevention (CDC) and the United States Department of Agriculture (USDA) continue to investigate the cause of this outbreak. This includes continued inspections and sample collection in facilities, the environment and water, as well as studies of animal management, water use, and the environment.

FDA announced on September 29, 2006 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 CDC. Natural Selection Foods issued a recall of all implicated products on September 15, 2006. Four other companies have issued secondary recalls because they received the recalled product from Natural Selections. See below for a complete list of brand names that are subject of the recalls. Spinach processed by other manufacturers has not been implicated in the outbreak.

Next Steps

There has been a long history of E. coli O157:H7 outbreaks involving leafy greens from the central California region. Spinach processed by other manufacturers has not been implicated in this outbreak, but based on discussions with industry, and given the past E. coli O157:H7 outbreaks, FDA and the State of California still expect the industry to develop a comprehensive plan which is designed to minimize the risk of another outbreak due to E. coli O157:H7 in spinach grown in central California. While this plan is under development, FDA and the State of California reiterate previous concerns and advise firms to review their current operations in light of the agency's guidance for minimizing microbial food safety hazards.

FDA and the State of California have previously expressed serious concern with the continuing outbreaks of foodborne illness associated with the consumption of fresh and fresh-cut lettuce and other leafy greens. After discussions with industry, FDA and the State of California, as part of a longer term strategy, now expect industry to develop a plan to minimize the risk of another outbreak due to E. coli O157:H7 in all leafy greens, including lettuce.

The Grower Shipper Association of Central California, the Produce Marketing Association, the United Fresh Produce Association, and the Western Growers Association said, "We are committed to working together as one industry to learn everything we can from this tragedy, and will redouble our efforts to do everything in our power to reduce the potential risk of foodborne illness. As we have in the past, we will work aggressively with the Food and Drug Administration and state regulatory authorities to ensure the industry's growing and processing practices continue to be based on the very best scientific information available, and that we are doing everything possible to provide the nation with safe and healthy produce."

Implementation of these plans will be voluntary, but FDA and the State of California are not excluding the possibility of regulatory requirements in the future. FDA will be holding a public meeting to address the larger issue of food borne illness linked to leafy greens later in the year once the current investigation is complete.

Advice to Retailers, Food Service Operators and Consumers

FDA is still reminding the public that Natural Selection Foods has recalled all spinach products under multiple brand names with a date code of October 1, 2006 or earlier. There have been four other recalls from different companies because they received Natural Selection Foods spinach. See below for a complete list of brand names that are subject of the recalls.

In order to protect consumers, retailers and food service operators should not sell raw spinach or blends that may contain spinach that was processed by Natural Selection Foods and all other brands subject to the recalls.

Consumers are advised that proper storage of fresh produce can affect both quality and safety. To maintain quality of fresh produce, certain perishable fresh fruits and vegetables (like strawberries, lettuce, herbs, and mushrooms) can be best maintained by storing in a clean refrigerator at a temperature of 40° F or below. All produce that is purchased pre-cut or peeled should be refrigerated to maintain both quality and safety.

Many precut, bagged produce items like spinach and lettuce are pre-washed. If so, it will be stated on the packaging. This pre-washed, bagged produce can be used without further washing.

Processed spinach (e.g., frozen and canned spinach) is not implicated in this outbreak.

Symptoms of E. coli O157:H7 Illness

E. coli O157:H7 causes diarrhea, often with bloody stools. Although most healthy adults can recover completely within a week, some people can develop a form of kidney failure called HUS. HUS is most likely to occur in young children and the elderly. The condition can lead to serious kidney damage and even death.

Lettuce Safety Initiative

The FDA developed the Lettuce Safety Initiative www.cfsan.fda.gov/~dms/lettsafe.html in response to recurring outbreaks of E. coli O157:H7 in lettuce. As a result of this outbreak, the initiative has been expanded to cover spinach. The primary goals of the initiative are to reduce public health risks by focusing on the product, agents and areas of greatest concern and to alert consumers early and respond rapidly in the event of an outbreak. This initiative is based on the 2004 Produce Safety Action Plan, intended to minimize the incidence of food borne illness associated with the consumption of fresh produce.

Additional Information

FDA continues to work closely with the CDC and state and local agencies to determine the cause and scope of the E. coli O157:H7 outbreak in spinach. Please check www.fda.gov for updates.
