Update - Listeria Contaminated Caramel Apples

The CDC reports as of January 1, 32 people have become ill with 6 deaths related to Listeria contaminated caramel apples.

The FDA investigation traced the apples to Bidert Brothers Packing of CA.  Their Granny Smith and Gala Apples appear to be the likely source.   Companies which received apples from Bidert Bros issued recalls.

Quat Sanitizer - a Review of Efficacy

 A review article, Quaternary Ammonium Biocides: Efficacy in Application, published in Applied and Environmental Microbiology, looks at the use of quat, or quaternary ammonium, sanitizers and the fact that some organisms may be more tolerant than others.  It states that this is a tolerance issue, not a resistance issue.  So while the use of quat sanitizers are important, more information is needed in field application to understand real efficacy and survival.

ABSTRACT

Bacteria in the Restroom - Pondering Succession and Stability

Did you ever wonder about the bacteria on the surfaces in the restroom?  Well, you probably figured there were bacteria there (and thus you use your foot to flush the commode), but hopefully you pondered deeper thoughts rather than postulating bacterial succession on the floor as well as the seat in which you sit.

Well some did ponder such questions, completed a study and published those results (Ecological Succession and Viability of Human-Associated Microbiota on Restroom Surfaces).  They showed that the ecological succession of bacterial populations does occur and that in general, a stable community does occur after 8 hours, and is made up of skin and environmental organisms rather than gut microorganisms.

"The prevalence of skin-associated, rather than feces-associated taxa, in the late-successional community suggests that organisms are selected for their ability to persist in a dry, aerobic environment, which is a very different environment from the gut. Human-associated microbiota, including Staphylococcus strains, can remain viable on BE surfaces for many hours after their dispersal [cleaning] agents are removed. This suggests that common BE surfaces may be significant fomites for viable human pathogens."

Caramel Apples Linked to Listeria Outbreak, 5 Reported Deaths

Caramel Apples, commercially produced and prepackaged, are being linked to a Listeria outbreak that has caused 5 deaths and 21 hospitalizations in 10 states.

 While we have recently seen recalls related to Listeria being detected on apple slices, this is one of the first cases of a Listeria outbreak related to apples.  Considering that there are as many illnesses and deaths, this is the type of outbreak that will have a huge impact on fruit packers and processors.

At this point, there is little information on the circumstances, but certainly more will follow.

Melted caramel is liquid in the 125F to 150F range, so depending on how fast it cooled, Listeria could survive on the surface.  It also could be forced into the apple via the wooden stake.

At this point, it may be wise to avoid caramel apples.

Well here is a scenario….

 

• Apples that were probably washed, but in less-than-sanitary quality water contaminates the apple, and most importantly the calyx.  
• Apples were stored prior to adding caramel, providing a greater chance for biofilm formation at the calyx end.
• The stick, when shoved into the calyx of the apple, drags the inoculum into the center of the apple.
• The core, perhaps not having as low a pH compared to the cells in the pulp, may be more apt to support the growth of Listeria.
• Growth is further supported by the storage of those apples at room temperature..and that temperature may even be higher in that those apples were dipped in the warm caramel.
• If the processor used bulk storage apples, the conditions for supporting biofilm would probably be greater.
• Caramel apples can have a sell-by-date as long as one month, and this will provide more opportunity for growth, even if that growth is slow.

 

Potential Controls for Consideration:

• Using tree run fruit that is sorted for fresh sales.
• Sanitizing apples followed by proper drying.  Sanitizer concentration must be controlled.
•  Storage of fresh apples at refrigerated temperature in boxes with separators.
•  Pre-dip the sticks in an acid sanitizing solution.
•  Chilling apples after dipping in caramel,
•  Storage of the caramel apples at refrigeration temperature.
• Limit shelf-life of caramel apples.
•  Can the calyx of the apple be removed?

  

We will need to see what the conditions for processing these caramel apples were to get a better idea of what happened.

Multistate Outbreak of Listeriosis Linked to Commercially Produced, Prepackaged Caramel Apples

 

Posted December 19, 2014 9:30 AM ET

 

Highlights

• Read the Advice to Consumers and Retailers>>(http://www.cdc.gov/listeria/outbreaks/caramel-apples-12-14/advice-consumers.html)
• CDC is collaborating with public health officials in several states and with the U.S. Food and Drug Administration (FDA) to investigate an outbreak of Listeria monocytogenes infections (listeriosis) linked to commercially produced, prepackaged caramel apples. Listeria can cause a serious, life-threatening illness.
• The information CDC has at this time indicates that commercially produced, prepackaged caramel apples may be contaminated with Listeria and may be causing this outbreak.
• Out of an abundance of caution, CDC recommends that U.S. consumers do not eat any commercially produced, prepackaged caramel apples, including plain caramel apples as well as those containing nuts, sprinkles, chocolate, or other toppings, until more specific guidance can be provided.

As US Poultry Industry Braces for the Potential of Avian Flu, H5N2, People Not at Risk

Avian influenza has been found in wild birds on the US border.  USDA has not found it in in US poultry, but the strains H5N2 and H5N8 have been found in Canadian and European flocks.  While these strains are highly pathogenic to birds, they are not considered a risk to people.
 
Migratory birds such as ducks are a risk factor for spreading the virus to the US poultry population.  Once infected, the flock is often culled to eliminate further risk of spreading the virus.

Just this past year, the pork industry suffered the fate of the PED virus, or Porcine epidemic diarrhea virus.  PEDV causes severe diarrhea in pigs and has a high lethality in piglets, but poses no risk to other animals or humans.   PED and Influenza are different types of viruses. PED is from the Coronaviridae family of enveloped, positive-stranded RNA viruses.  Influenza is an Orthomyxovirus.

H5N2, H5N8 avian flu viruses surface in US

Dec 16, 2014

US authorities today reported finding wild birds in Washington state infected with two different highly pathogenic avian influenza (HPAI) viruses, H5N2 and H5N8, raising questions about possible connections with recent H5N2 outbreaks across the border in Canada and with an Asian H5N8 strain that is now hitting European poultry farms.

In reports to the World Organization for Animal Health (OIE), the US Department of Agriculture (USDA) said H5N2 was found in a wild pintail duck, while H5N8 was found in a captive wild gyrfalcon that was fed on hunter-killed birds. Both birds were in Whatcom County, Washington, which borders the Abbotsford area of British Columbia, the site of recent H5N2 outbreaks in poultry.
