Favorite Research Paper Award Discusses Salmonella and Wild Birds

What is your favorite clinical microbiology research paper form 2023? Not a question I have ever been asked or even thought about. Favorite movie or favorite restaurant visit, sure, but can't say I have a favorite clinical microbiology paper. Well some microbiology geeks picked a paper authored by one of our favorite Penn State microbiology geeks, Dr. Ed Dudley's research paper as their favorite paper. Awesome. Congrats to him and his collaborators. And to the editors point, it has a lot going for it ....Salmonella, wild birds, evolution, and One Health.  We can think about this as it relates to food in that wild birds are a source of Salmonella within the food supply chain.

Whole-Genome Subtyping Reveals Population Structure and Host Adaptation of Salmonella Typhimurium from Wild Birds
https://journals.asm.org/doi/10.1128/jcm.01847-22

ABSTRACT

Within-host evolution of bacterial pathogens can lead to host-associated variants of the same species or serovar. Identification and characterization of closely related variants from diverse host species are crucial to public health and host-pathogen adaptation research. However, the work remained largely underexplored at a strain level until the advent of whole-genome sequencing (WGS). Here, we performed WGS-based subtyping and analyses of Salmonella enterica serovar Typhimurium (n = 787) from different wild birds across 18 countries over a 75-year period. We revealed seven avian host-associated S. Typhimurium variants/lineages. These lineages emerged globally over short timescales and presented genetic features distinct from S. Typhimurium lineages circulating among humans and domestic animals. We further showed that, in terms of virulence, host adaptation of these variants was driven by genome degradation. Our results provide a snapshot of the population structure and genetic diversity of S. Typhimurium within avian hosts. We also demonstrate the value of WGS-based subtyping and analyses in unravelling closely related variants at the strain level.

An selected items from the paper as it impacts food.

"As indicated in this study, wild animals such as wild birds represent remarkable but less studied reservoirs for emerging variants of bacterial pathogens. Epidemiologic studies have also revealed a correlation between some human and avian salmonellosis outbreaks, suggesting transmission of bacterial pathogens between wild birds and humans (55–59). Although such transmission is rare relative to transmission between humans and humans or between humans and domestic animals (72, 73), they can still have a substantial impact on global health as avian hosts are highly mobile and possibly carry and spread bacterial pathogens over large distances (44, 45). In a One Health framework, current surveillance of bacterial pathogens needs to be focused not only on clinical isolates or isolates from domestic animals but also on those originating from wild animals."

CDC - Salmonella Outbreak Associated with Cantaloupes is Over, 407 Reported Cases

CDC released notice that the 2023 Salmonella outbreak linked to cantaloupes is over.  Cases were first identified in October 2023, with recalls being issued in November, 2023 by SOFIA PRODUCE, LLC, of Nogales, Arizona which does business under the name “Trufresh”.

FDA testing did link the company to the outbreak, but little additional information from the investigation was found.

PA Distributor Recalls Dried Mango for Undeclared Sulfites

TRUONG GIANG DISTRIBUTOR CORP of Philadelphia, PA is recalling Golden Owl Dried Mango, because it may contain undeclared sulfites.   The recall was initiated after routine sampling by the New York State Department of Agriculture and Markets found sulfites in the product which was distributed in packaging that did not reveal the presence of sulfites. Subsequent investigation indicates the problem was caused by a temporary breakdown in the supplier’s labeling processes.

Can Kiwifruit Improve Your Mood?

Can Kiwifruit improve your mood?  "In a study, published in The British Journal of Nutrition, researchers found the furry fruit improved vitality and mood in as little as four days."  Just two kiwifruit per day was better than the vitamin C placebo. 

"Vitamin C intake has been associated with improved mood, vitality, well-being, and lower depression, while vitamin C deficiency is associated with higher depression and cognitive impairment.  Participants took daily either a vitamin C supplement, placebo, or two kiwifruit. They then reported their vitality, mood, flourishing, sleep quality, sleep quantity, and physical activity using smartphone surveys.  The researchers found kiwifruit supplementation improved vitality and mood within four days, peaking around 14–16 days, and improved flourishing from day 14. Vitamin C, on the other hand, marginally improved mood until day 12."

This research was funded by the University of Otago [New Zealand University] and Zespri International [a kiwifruit grower cooperative].

France - Gourmet Christmas Party Source for 700 Cases of Norovirus Infection

Many of us do not get the opportunity to attend those fancy company Holiday parties where gourmet food is served.  Well, here is one party you should be happy you were left off the invite list.  In France, Airbus held a Christmas party for its employees where 700 of them came down with Norovirus infection

"Jean-Claude Iribarren, the secretary of the Airbus Atlantic works committee, told the paper the food had been prepared by the company’s canteen. “As we do every year, we organised a Christmas dinner for 2,600 people with a lot of local suppliers,” he said."

Unfortunately, for 700 of them, they became sick with vomiting and diarrhea. "The affected workers showed “clinical signs of vomiting and/or diarrhoea” after the seasonal dinner on 14 December. Most fell ill within 24 to 48 hours after the meal.

Oregon Firm Recalls Yogurt Yogurt Product for Undeclared Allergens

Al Amir Fresh Foods of Milwaukie, Oregon is recalling Al Amir brand hummus dip products due to undeclared sesame and Tzatziki Cucumber Yogurt due to undeclared milk.   The recall was initiated after it was discovered that Al Amir hummus labels declare tahini but do not declare sesame and Tzatziki Cucumber Yogurt label declares sour cream & yogurt but does not declare milk. 

I guess the company never got the memo that allergen labeling was required on food products.

USDA FSIS Issues Public Health Alert for NY Establishment's Raw Pork Dumpling Product Produced Without Federal Inspection

USDA-FSIS issued a Public Health Alert for raw frozen dumpling product "because Dim Sum Factory Inc., a Flushing, N.Y., establishment, produced and distributed raw, frozen pork dumpling products without the benefit of federal inspection."  The problem was discovered during routine FSIS surveillance activities. FSIS determined that the location where the pork wonton products were being produced were not on the official premises of the establishment and, therefore, were not inspected.

There have been no confirmed reports of adverse reactions due to consumption of these products. Anyone concerned about an injury or illness should contact a healthcare provider.
