CDC Report - 2014 Case of Ciguatera Toxin in Florida After Consuming Naturally Contaminated Black Grouper

In a CDC report, in 2014, a Florida woman contracted ciguatera fish poisoning after eating black grouper in a restaurant.  Five additional cases were also reported, also associated with black grouper from the same international supplier.

About 7 hours after eating black grouper, the woman experienced acute onset of neurological symptoms including paradoxical temperature perception (burning sensation like dry ice), paresthesias (tingling or pricking or “pins and needles”, in the peripheral nerves), extremity numbness, a metallic taste, nausea, vomiting, abdominal pain, diarrhea, arthralgia, and myalgia.

Ciguatera fish poisoning (CFP), occurs when predatory reef-dwelling fish harboring ciguatoxins is ingested.  Ciguatoxin is stable to both freezing or cooking.   The naturally occurring toxin originates in several dinoflagellate (algae) species.  That toxin accumulates in the meat of preparatory reef fish as they eat smaller fish that have eaten the toxic algae.

California Restaurant Source of Shigella - Number of Cases Continues to Climb

UPDATE (10/23/15)- Within a few days, the number of Shigella cases linked to a California restaurant continues to climb.  Reports now have the number at 110 cases in 4 different California Counties.

10/20/15
A California restaurant is being held responsible for up to 80 people becoming infected with Shigella with about a dozen becoming hospitalized.  Because this is a highly contagious bacterial infection, a number of secondary infections are beginning to arise. (People who are contracting the disease from someone who ate at the restaurant).
Shigella causes severe diarrhea, sometimes bloody, as well as fever and abdominal pain. Symptoms will occur within a day or two after infection and will last 5 to 7 days.  It is highly infectious, only requiring less than 20 cells to cause infection.  It spreads through contact with food or person to person which can be problematic when someone has profuse diarrhea and does not wash their hands or washes their hand insufficiently. 
 
Glove usage handling ready-to-eat foods would help...but that is not a law in CA.  In 2014, California repealed the law requiring glove usage to prevent bare hand contact with ready-to-eat food.

Getting sick workers to stay home is another issue.  Many people will still go to work even if they are ill.

Bottles of Sparkling Beverage Recalled Due to Potential for Glass Fragments

Martinelli, a California bottler of sparkling fruit juice is recalling certain lots of Martinelli’s 8.4 oz. mini glass bottles of cider and sparkling grape juice due to the possibility of small glass chips at the top of the bottles occurring when opening the bottle, which could possibly enter the beverage and cut or injure the consumer.
The company discovered the issue through their own internal testing.

Fresh Whole Apples Recalled Due to Positive Listeria Test

Del Monte Fresh Produce is recalling apples for potential Listeria contamination after a customer tested fresh apples and found a sample to be positive for Listeria monocytogenes.

Listeria has not been an issue in whole fresh apples, and would be considered low risk. But caramel apples have been linked to an outbreak and sliced apples have been recalled due to the presence of Listeria.  In a recent study, Listeria was shown to grow only minimally on whole apples with caramel (no stick) and no growth when those caramel apples (no stick) were stored at refrigeration temperatures.  Even sliced apples shows minimal growth especially at refrigeration temperatures.

Del Monte Fresh Produce N.A., Inc., (“Del Monte Fresh”) is initiating a voluntary recall of Granny Smith green apples because they have the potential to be contaminated with Listeria monocytogenes, an organism which can cause serious and sometimes fatal infections in young children, frail or elderly people, and others with weakened immune systems. Although healthy individuals may suffer only short-term symptoms such as high fever, severe headache, stuffiness, nausea, abdominal pain and diarrhea, Listeria infection can cause miscarriages and stillbirths among pregnant women.

Research Findings on Listeria Growth in Caramel Apples

The Listeria outbreak associated with caramel apples has raised questions regarding how the Listeria was able to grow in an acidic fruit.  Researchers have found that inserting the stick in the apple was an important factor as well as also storing at room temperature.  So when the stick is inserted, it drives the organism into the apple, and the stick causes cellular damage to the apple, creating conditions that allow the Listeria to grow sufficiently when stored at room temperature.

It would be wise for those selling caramel apples to store them at refrigeration temperature and limit the shelf-life to less than 28 days.

The other point made by the researchers in this study is the concept of microenvironments existing at interfaces in food, in this case, the interface of stick and the apple.  When inserted, the stick changes the apple matrix enough to allow Listeria to grow.  Normally, the apple pH would be too low to support the growth of Listeria.

It is easy to overlook microenvironments that exist in food.  They can arise in multicomponent foods with particulates, in foods at the packaging interface, or in foods that allow moisture migration to surface changing the moisture content.  The interaction at these interfaces can impact preventive factors such as pH,  water activity (Aw), or preservative concentration.

ABSTRACT
A 2014 multistate listeriosis outbreak was linked to consumption of caramel-coated apples, an unexpected and previously unreported vehicle for Listeria monocytogenes. This outbreak was unanticipated because both the pH of apples (<4.0) and the water activity of the caramel coating (<0.80) are too low to support Listeria growth. In this study, Granny Smith apples were inoculated with approximately 4 log10 CFU of L. monocytogenes (a cocktail of serotype 4b strains associated with the outbreak) on each apple’s skin, stem, and calyx. Half of the apples had sticks inserted into the core, while the remaining apples were left intact. Apples were dipped into hot caramel and stored at either 7°C or 25°C for up to 11 or 28 days, respectively. Data revealed that apples with inserted sticks supported significantly more L. monocytogenes growth than apples without sticks under both storage conditions. Within 3 days at 25°C, L. monocytogenes populations increased >3 log10 in apples with sticks, whereas only a 1-log10 increase was observed even after 1 week for caramel-coated apples without sticks. When stored at 7°C, apples with sticks exhibited an approximately 1.5-log10 increase in L. monocytogenes levels at 28 days, whereas no growth was observed in apples without sticks. We infer that insertion of a stick into the apple accelerates the transfer of juice from the interior of the apple to its surface, creating a microenvironment at the apple-caramel interface where L. monocytogenes can rapidly grow to levels sufficient to cause disease when stored at room temperature.

CDC Announcement - October 15th is Global Handwashing Day

While many may scoff, or even mock, those federal officials for putting such effort into creating a 'day' for such a menial task as handwashing, perhaps this is an opportunity to remind all those who handle food of the importance of handwashing.  You may even want to go as far as having a handwashing retraining event....A Handwashing Celebration Extravaganza!

SHOW US THOSE CLEAN HANDS!
