The most recent illness was diagnosed on January 31, 2016.

CDC MMWR - 2014 Botulism Outbreak Associated with Farm Stand Pesto

CDC MMWR has a report on the 2014 botulism outbreak associated with pesto purchased from a farm stand.  Two individual contracted the disease when sharing dinner of chicken with the tainted pesto.

In the report they found "Environmental assessment of company A identified improper acidification and pressurization practices and lack of licensure to sell canned products commercially, including products in hermetically-sealed jars......Health officials in California collected and analyzed an unopened jar of the pesto from this family member’s house. It was found to have a pH of 5.3 and water activity* of 0.965 (parameters insufficient to prevent growth of C. botulinum)."

The report goes on to state that "As the demand for locally made, ready-to-eat food increases, consumers and public health officials should be aware of the risk for botulism from improperly canned foods such as pesto sold in jars. Producers of canned foods for commercial use should ensure that they adhere to food safety regulations."

(More information on this outbreak in our 2014 report.)

FDA Reports on the Contamination of Imported Spices, but not Retail Spics...Yet

FDA published a Q and A on the safety of spices looking at the contamination rates of incoming spices.   In a nutshell, the US imports spices from 79 countries, and of these, salmonella contamination was found in spices from 37 countries.  The also found that "Spice shipments offered for entry into the U.S. had an overall prevalence for Salmonella of approximately 6.6 percent during the 2007 to 2009 fiscal years, about twice the average prevalence of all other imported, FDA-regulated foods"

But this is not really a thing because spices are generally treated once they arrive in the US and these were not yet treated.  According to the website, "However, we noted in the study an important data gap in that we were missing key information about the level of contamination of spices at retail in the U.S. When we began conducting the risk profile, we asked the public for any data but did not receive information about contamination rates at retail. Because many imported spices are treated after entry to the U.S. to reduce contamination before they are sold to consumers, we knew that the 6.6 percent contamination rate found at the import level did not reflect what was actually reaching consumers."

Did they collect retail samples? Yes, but that data was not ready to release.

Outbreak of E. coli in MN and WI Associated with Spouts

There is a second outbreak occurring with sprouts announced within the week, but this MN / WI based outbreak is associated with E. coli STEC.

The other spout related outbreak, which is based in Kansas, is due to Salmonella.

Mitigating Food Safety Issues - Monitoring of Social Media

Wall Street Journal has an interesting read about mitigating food safety risks.  Some of the keys mentioned are right on target..."Companies need strong food safety policies that are enforced, extensive employee training and messaging and regular checking of their supply chains through audits, and product testing to help mitigate their risks.."  Then monitoring is discussed at length with specific attention to monitoring of social media.  The point they make is that monitoring social media may be helpful, but it is far from full proof.  Case in point was the Chipotle outbreak where social mentions months before the outbreak were not much different than that during the outbreak.

There are times monitoring social media can help, like the case earlier this year when LA County Health identified an outbreak at a restaurant.  But monitoring of social media has its drawbacks, as we pointed out last year when it was highlighted in the news media as the next best thing in the fight against foodborne illness.  Those who monitor consumer complaints will probably tell you, sometimes a complaint of illness here or there is common, and it can be difficult in telling what is real and what is either a misinterpretation of cause by the consumer (they picked the last thing they ate,  it was a seasonal illness, etc) or the consumer just wanted to complain.

As part of the company's food safety system, monitoring of complaints made formally or made through social media can all help in identifying an issue earlier, but it is far from clear cut.  Much of it will be establishing procedures for identifying key words or patterns in the data.  Best efforts however, are putting policies and procedures in place to prevent issues in the first place.

Awareness, Training, Oversight Keys to Mitigating Food Safety Risks
February 25, 2016
By Ben DiPietro Biography

The recent food sickness problems at Chipotle Mexican Grill Inc.—the chain suffered an E.coli outbreak that led to restaurant closures in nine states and a norovirus outbreak that sickened 140 people in Boston–placed a spotlight on risks faced by companies that sell food.

Companies need strong food safety policies that are enforced, extensive employee training and messaging and regular checking of their supply chains through audits, and product testing to help mitigate their risks, according to food safety experts. Monitoring of social media for early-warning signals of possible foodborne illness issues can be helpful and should be done but won’t always help prevent or contain outbreaks, they said.

Raw Can Be Risky When it Comes to Nuts and Sprouts - Salmonella Related Recalls

Within the last week, there have been recalls of raw nuts and raw sprouts and raw sprout products due to the potential for Salmonella after those products were tested and found to be Salmonella positive.  Surprising....not really.  Makes you feel like that infant in the e-trade commercial feigning a sense of shock at a very predictable outcome.


Raw sprouts and raw nuts are a risk for pathogenic organisms like Salmonella.  There are no significant pathogen reduction steps.  And although some may suggest testing as a control, it is hit or miss when there are low levels of contamination - so testing as verification but not as control.

Corrugated Packaging Process Sufficient to Eliminate Pathogenic Bacteria

The Corrugated Packaging Alliance (CPA) sponsored a study that evaluated the impact of the corrugation process on bacterial pathogens.  The study found that the high temperatures used (180 to 200ºF were sufficient to achieve a 5 log reduction of bacteria such as E. coli and Salmonella.  We normally would not have considered corrugated boxes an issue, well, now here is the documented proof.
If you want this study for your validation files, you can download that document here.

TEMPERATURE, TIME TESTING PROVES CORRUGATION PROCESS DESTROYS BACTERIA
ITASCA, IL (FEBRUARY 2, 2016) – A new study shows the process of combining linerboard and medium to make corrugated packaging is sufficient to destroy common food pathogens, effectively meeting the U.S. Environmental Protection Agency’s (EPA) requirements for chemical sanitizers.

Cheese Processor Expands Recall of Cheese with Potential for Listeria

Maytag Dairy Farms expanded its recall to include additional lots of cheese that may be contaminated with Listeria.  This initial recall, posted on February 14th, was expanded to one other lot on February 18th and then additional lots were added to the recall on February 19th.  

Unfortunately, this issue, the expanding recall or recall creep, has been seen with other Listeria related recalls.  It starts when a lot of product is recalled in reaction to a Listeria positive sample - it could be product or product contact sample. But once the regulatory folks start poking around, the realization comes that the company does not have a solid understanding of how well they are controlling Listeria.  This is not to say they were not doing Listeria testing,  but the testing program was not providing sufficient data to establish a sense of control.

On the other hand, there are examples of companies who have had recalls, but upon analysis of their faculties, the assessment is made that the positive sample was a aberration based on a solid Listeria control program (sanitation SSOPs, process control, and verification testing.)
