CDC Report on 2015 Salmonella Outbreak Associated with Truffle Oil

CDC issued a report on a 2015 outbreak of Salmonella Enteritidis associated with a Washington DC restaurant.  There were 159 reported cases.  Truffle oil was the most likely source based on the epidemiological investigation, but the organism was not isolated from the oil itself.   "Six food items were significantly associated with case status (Table 2), three of which (beef carpaccio, truffle mushroom croquette, and truffle risotto) contained truffle oil. When all truffle oil–containing items were combined into a single variable, including the three that were individually significant, consumption of a truffle oil–containing item was reported by 89% of case-patients compared with 57% of control subjects (p<0.001)."

While this Salmonella strain is normally associated with poultry and eggs, it was unusual that truffle oil was the likely source.  And being a common pathogen, the report indicates that "Timely engagement of the public, health care providers, and local and federal public health officials, is particularly critical for early recognition of outbreaks involving common foodborne pathogens, such as Salmonella Enteritidis"  Basically, by really looking hard, investigators were able to determine that something different was going on, and in doing so, were able to determine the restaurant was involved.  At that point, they closed the establishment thus preventing additional cases that would have most definitely occurred.

As far as testing "Truffle fries sampled from the deep fryer and uncooked truffle mushroom croquettes were among the samples collected on September 10; a truffle oil sample was collected on September 14."  "DCPHL tested the truffle fries, which screened positive for Salmonella by using polymerase chain reaction (PCR), but Salmonella was not isolated during confirmatory testing. All other food and environmental samples were negative for Salmonella."

Another outbreak in the same restaurant chain indicated the issue may have originated in a NY commissary where the oil originated (but not sure if made there).  It seems the commissary had gone through purge and sanitize procedure, so nothing was found there when investigators inspected that operation.

So before we throw truffle oil on the list per se, there should be additional information as to where it was made.  This may be more of a commissary issue that a truffle issue.

Frozen Pizza with Meat Recalled After Listeria Positive Test Results

A California establishment is recalling frozen, supreme-style pizza after the company's testing confirmed Listeria contamination.

While the product is frozen, which would prevent growth, and it has directions for cooking, which if done properly would eliminate the pathogen, one can never know how the product will be handled b the store and prepared by the consumer.  If similar to those sold here, they are sold refrigerated.

NY Creamery Expands Recall, Product Linked to Illnesses. 2 Deaths

A NY creamery expanded its recall, posted on 3/7/16, as the CDC has linked the product to 6 cases of listeriosis.  There have been 2 deaths.

The product had national distribution, and with the window of time until the product was recalled, there may be additional cases that may be reported.

Listeria can be problematic in soft cheeses in that the product will support the growth of Listeria  We have seen a number of cases of listeria related to soft cheeses, so it is incumbent on those packing soft cheeses to have an aggressive Listeria control program. 

Harder cheese have a lower water activity and will not support the growth of Listeria.  While the risk is lower, the food plant-environmental pathogen still needs to be controlled.

CDC Report - 2016 Salmonella Outbreak in Children Associated with Playground Sand

A 2016 Salmonella outbreak in Madrid, Spain caused illness in 24 preschool students, aged 3 to 5 years old.  It was concluded that the source of the Salmonella was the sand in the playground.  The Salmonella likely got there through bird droppings.   

While these types of issues may be difficult to prevent, there are some preventive measures that can be taken.  Keeping children from putting their hands in their mouth when playing in the dirt. (Good luck with that).  Having kids wash their hands after playing.  Recognizing that bird droppings are a potential source of Salmonella, so placing sandboxes in areas away from trees and other overhead structures where birds may land (and poop).  Sure, trees provide shade, and in Spain, it is probably better to be in the shade.  However, structures such as large umbrellas may be used.  Umbrellas or other movable structures can be beneficial in allowing the sand to dry.

Cheese Ravioli Product Recalled for Missing Allergen in "Contains" Statement

Gerber is recalling its Cheese Ravioli Pasta Pick-ups for a allergen labeling issue - while allergen egg is listed in the ingredient listing, it was missed in the 'Contains' statement.

FALCPA (Food Allergen Labeling and Consumer Protection Act of 2004) requires that the label of a food that is fabricated from two or more ingredients declare each ingredient by its common or usual name.  It can do this either in the ingredient listing or it can highlight the allergens included in the product with a "Contains" statement.   However, FDA provided further guidance that if the company chooses to use the "Contains" statement, all major allergens in the product must be listed.  (FDA referenced documents below).

So in this case, while the ingredient  egg was in the ingredient listing, it was missed in the "Contains' statement.

MI Food Pantry Temporarily Closed - A Reminder for Donated-Food Distributors

The Michigan Department of Agriculture and Rural Development temporarily closed a food pantry after they inspected the facility.   The inspection came in response to a complaint, and numerous issues were found including moldy food and poor personnel practices.

While food pantries are given latitude in providing expired food, the food still must be edible.  Food inventories must be managed, removing items as they get excessively old or grow mold.  Another practice is taking bulk food and repacking it.  The repackaging process must be done following sanitary procedures including handwashing, and the smaller packages must be labeled.

Food pantries do a great service, but the people they serve must receive safe food.
