    Outbreaks happen all the time. The majority are avoidable and can be linked to a few factors or bad decisions. While I'm a self-described outbreak junkie, it's not the gore of vomit and barf associated with tragic incidents that I'm interested in. While the stories are important, I'm not into embellishment to scare folks into behavior change. The philosophy I subscribe to is to present folks who make decisions, from the teenage produce stock boy to the CEO of a food company, with the risks and consequences of their actions. And let them make a decision. Hopefully they choose to avoid making people sick.
    I'm an outbreak junkie because the sick and the dead are real people with families; individuals whose lives changed because they ate something. Something, for the most part, that wasn't supposed to make them ill.

    And if nothing is learned from those illnesses, and changes made, food doesn't get any safer.

    In an article in the Yuma Sun detailing produce farmer responses to upcoming Food Safety Modernization Act-related regulatory changes Kurt Nolte, executive director of Yuma County Cooperative Extension references a 2010 E. coli O145 outbreak linked to fresh produce. Investigators connected 33 cases (12 of which were hospitalized) with Arizona grown romaine lettuce.

    “Data suggests the grower followed all guidelines,” Nolte said. An investigation traced the probable cause to a leaking septic tank in a vehicle park some distance away.

    It's frustrating when food folks say that all the right guidelines were followed and illnesses still happened. When this happens food safety professionals aren't doing their jobs. Either the guidelines aren't as good as they thought or implementation faltered (or a combination of both).

    What was left out is that the FDA environmental assessment showed that maybe all guidelines weren't followed. While the ultimate source of contamination was the septic tank, water used for diluting pesticides and fertilizers, and for irrigation, is the most likely vehicle of pathogen transmission onto/on the farm.

    Liquid pesticides and fertilizers used on the lettuce crops were diluted with both municipal and local irrigation canal waters. Municipal water is treated and periodically monitored. Based on these factors, the municipal water was not considered a reasonably likely source of contamination.

    Arizona Leafy Green Marketing Agreement guidelines do have parameters for microbial testing of water that is applied directly to the product, which includes microbial testing. Would be nice to see the history of the test results from the producer for the irrigation canals (and if it did happen, it would have been nice to see mention in the FDA environmental assessment. If the sampling didn't provide any indicators of a problem the guidelines need to be revisited as Nolte notes, “From that incident, our charge is to research the risk of septic tanks leaking deep underground that may leach into a dirt irrigation ditch.”

    Yeah, and show other producers the consequences of mixing potentially risky irrigation water with fungicides and pesticides.

    The Yuma Sun reports a recent increase in a rare nervous system disorder that can lead to paralysis has led the U.S. Centers for Disease Control and Prevention to send agents to Yuma to investigate.

    Health officials announced Wednesday that health officials in Yuma County and San Luis Rio Colorado, Son., have reported an increase in acute diarrheal illnesses caused by campylobacter infections and cases of Guillain-Barre' Syndrome (GBS) over the past three months.

    As of July, there have been six confirmed cases and one pending case of GBS in Yuma County, said Becky Brooks director of the Yuma County Health District.
    In a normal year, there are typically three to four cases.

    “(In June) we started noticing an increase in the campylobacter infection first,” Brooks said. “And then we started hearing about a syndrome they call acute flaccid paralysis. There had been some people who had gone to (the Yuma hospital) and had been sent to Phoenix.

    “Once we started hearing those names a few times, we started checking into it. That's when we contacted the state, and the state then contacted the CDC.”

    The CDC confirmed the increase in GBS constituted an “unusual cluster,” which happens with a variety of diseases and for a variety of reasons to occur across the country at any given time, Brooks said.

    New developments in the Freshway Foods romaine lettuce E. coli O145 outbreak:

    1. Why the corporate finance dude shouldn’t be the public spokesthingy.

    Freshway Foods recalled romaine lettuce products sold for food service outlets, wholesale, and in-store retail salad bars and delis last week after links with over 50 sick people in Ohio, Michigan and New York were established.

    The U.S. Food and Drug Administration said that multiple lines of evidence implicated shredded romaine lettuce from one processing facility as a source of infections in a multistate outbreak to which this recall may be related.

    “The evidence includes preliminary results of product traceback investigations that indicate:
    • the shredded romaine lettuce consumed by ill persons in three states originated from one processing facility;
    • preliminary results of a case-control study in one state that found a statistically significant association between E. coli O145 infection;
    • ingestion of lettuce from the same processing facility; and,
    • recovery of E. coli O145 from an unopened package of shredded romaine lettuce from the same processing facility that was obtained from a food service entity associated with the outbreak.”

    To which Freshway Foods vp of finance Devon Beer told The Packer,

    “It’s really a precautionary step.”

    No. It’s an outbreak and a public health step. At what point did FDA abandon epidemiology and require positive test results in an unopened package? How long were people eating potentially contaminated romaine lettuce at salad bars while regulators assembled sufficient evidence? What is the FDA policy on going public? (It doesn’t exist, at least not in any public form.) The six confirmed and suspected cases amongst students in New York’s Wappinger Central School District who came down with E. coli in April may want to know. And the lettuce they were served in the school cafeteria tested positive.

    2. The suspect lettuce was grown in Yuma, Arizona

    It was announced Friday that federal investigators were looking at a farm in Yuma, Ariz., as a possible source of the suspect romaine lettuce.

    3. Look for pathogens and they will be found

    In the wake of the E. coli O145 outbreak in romaine lettuce, a laboratory in Ohio started testing bags of romaine and found another E. coli which lead to a very private recall on Friday.

    Misti Crane of the Columbus Dispatch reported this morning that the E. coli positive (strain not identified – dp) led a California company to recall about 1,000 cartons of produce that went to two customers who then processed the lettuce before sending it on to food-service establishments.

    Amy Philpott, spokeswoman for Andrew Smith Co. in Spreckels, Calif., said none of the lettuce was sold in grocery stores and that only two food processors bought the cartons.

    She said she didn't know the names of those customers and did not know whether Freshway Foods in Sidney, Ohio, was one of them.

    Ohio Department of Agriculture spokeswoman Kaleigh Frazier said the test was on an unopened bag of Freshway romaine shredded lettuce with a sell-by date of May 10, and her department is sending the sample on to federal officials for further testing.

    Andrew Smith issued the recall privately on May 7 for lettuce that was shipped in mid-April, she said.

    4. Our stuff is safe

    As with the spinach outbreak of 2006, other regions are quick to proclaim the safety of their products, even in the absence of any data.

    New Jersey State Agriculture Secretary Douglas Fisher said Friday that fresh romaine lettuce from New Jersey is safe.

    "It certainly is an unfortunate coincidence of timing that this recall is occurring just as our farmers' fresh romaine is coming into the market, but there is no connection between the two."

    OK, but why not use the opportunity to explain the food safety steps taken by NJ lettuce growers to ensure microbiologically safe food, rather than saying we have a task force.

    5. Blame consumers

    Bob LaMendola of the Florida Sun Sentinel writes the E. coli is deadly but preventable by keeping raw meat separate from other foods, cooking meat to 165F, washing produce and hands vigorously.

    This has nothing to do with romaine lettuce at salad bars.

    After the 2006 E. coli O157:H7 outbreak linked to California spinach, the 29th outbreak linked to leafy greens and after years of warning from FDA, California growers formed the Leafy Greens Marketing Agreement, which is supposed to have food safety performance standards. Yet the most noticeable achievement since the Agreement has been the containment cone of silence that has descended upon outbreaks involving leafy greens, and an apparent shift in FDA policy that sets epidemiology aside and requires positive samples in unopened product – a ridiculous standard since no one routinely tests for other Shiga-toxin producing E. coli like O145.
