USA – Kawasho Foods USA Inc. Announces Expansion of Voluntary Recall of GEISHA Medium Shrimp 4oz. Due to Possible Under Processing

FDA

Kawasho Foods USA Inc. of New York, NY, is announcing an expansion of its February 26, 2023, voluntary recall of canned GEISHA Medium Shrimp 4oz. to now recall all lots of this product. Kawasho Foods is taking this step out of an abundance of caution due to a concern that there is a possibility that the product has been under processed, which could lead to the potential for spoilage organisms or pathogens.

Kawasho Foods made this decision after receiving additional information from the Food and Drug Administration.

The Product was distributed to retailers nationwide (AL, AR, AZ, CA, CO, CT, DE, FL, GA, IA, IL, IN, KS, KY, MA, MI, MN, MO, NC, NH, NJ, NY, OH, OR, PA, TN, TX, UT, VA, WA, WI) from Dec 2022 to Apr 2023.

The GEISHA Medium Shrimp is packaged in a 4oz. metal can, with UPC 071140003909 (Listed on the back of the label).

This event only affects this specific product.

Consumers should not use this product, even if it does not look or smell spoiled. No illnesses or other adverse consequences have been reported to date in connection with this product.

Consumers who have purchased this product are urged to return to place of purchase for a full refund. If you have any question regarding this recall, please contact us at Toll Free (224)278-9935 (Monday to Friday, 9:00 a.m. to 5 p.m. EST) or via email at info@geishabrand.com.

Research – Alternaria mycotoxins and its incidence in fruits and vegetables

Conicet

Alternaria is a ubiquitous fungal genus, widely distributedin the environment and a range of different habitats. It includes both plantpathogenic and saprophytic species, which can affect crops in the field orcause post-harvest spoilage of plant fruits and kernels. Numerous Alternaria species cause damage toagricultural products including cereal grains, fruits and vegetables, and areresponsible for severe economic losses worldwide. MostAlternaria species have the abilityto produce a variety of secondary metabolites, which may play important rolesin plant pathology as well as food quality and safety. Alternariol (AOH),alternariol monomethyl ether (AME), tenuazonic acid (TeA), tentoxin (TEN) andaltenuene (ALT) are considered the main Alternariacompounds thought to pose a risk to human health. However, food-borne Alternaria species are able to producemany additional metabolites, whose toxicity has been tested incompletely or nottested at all. Both alternariols are mutagenic and their presence in cerealgrain has been associated with high levels of human esophageal cancer in China.TeA exerts cytotoxic and phytotoxic properties, and is acutely toxic in differentanimal species, causing hemorrhages in several organs. The possible involvementof TA in the etiology of onyalai, a human hematological disorder occurring inAfrica, has been suggested. Altertoxins (ALXs) have been found to be morepotent mutagens and acutely toxic to mice than AOH and AME. Other metabolites,such as TEN, are reported to be phytotoxins, and their toxicity on animals hasnot been demonstrated up to now. Vegetablefoods infected by Alternaria rot areobviously not suitable for consumption. Thus, whole fresh fruits are notbelieved to contribute significantly with Alternariatoxins to human exposure. However, processed vegetable products may introduceconsiderable amounts of these toxins to the human diet if decayed or moldyfruit is not removed before processing. Thetaxonomy of the genus is not well defined yet, which makes it difficult toestablish an accurate relationship between the contaminant species and theirassociated mycotoxins. Great efforts have been made to organize taxa intosubgeneric taxonomic levels, especially for the small-spored, food associatedspecies, which are closely related and constitute the most relevant foodpathogens from this genus.Severalcrops of agricultural value are susceptible to infection by different Alternaria species and can contribute tothe entry of Alternaria mycotoxins inthe food chain. The distribution of Alternariaspecies was studied in different commodities grown in Argentina. These foodpopulations were characterized through a polyphasic approach, with specialinterest in their secondary metabolite profiles, to understand their fullchemical potential. Alternariaspecies associated with tomato, bell pepper, blueberry, apples and wheatcultivated in Argentina showed a surprisingly high metabolomic andmycotoxigenic potential. The natural occurrence of Alternaria toxins in these foods was also investigated. The resultshere presented will provide background for discussion on regulations for Alternaria toxins in foods.

Research – Deep ultraviolet fluorescence sensing with multispectral imaging to detect and monitor food-borne pathogens on the leafy green phyllosphere

Wiley Online

Demand for sustainable and safe raw agricultural commodities is growing rapidly worldwide. Reducing the risk of foodborne illnesses associated with fresh produce is a task which the industry and academic researchers have been struggling with for many years. There is an immediate need to devise a non-invasive optical detection system to monitor the food-borne pathogens on the leaf surface. The detection of foodborne pathogens on leafy produce is performed often too late because of the invasive techniques used to evaluate the pathogen colonization. Use of deep ultraviolet fluorescence (DUVF) sensing and visible–near infrared multispectral imaging (MSI) has previously been used to monitor plant interactions against both biotic and abiotic stress regimes. Using the patho-system that we developed to monitor Salmonella sp. and Listeria sp. ingression in leafy greens such as lettuce/spinach, we show that plant response in terms of fluctuation of chlorophyll pigments post-Salmonella/Listeria treatment is rapid. We also show that the mode of application of Salmonella/Listeria via foliar or root supplementation changes the ChlA response. Our data also reveals that the plant sentinel response in terms of early photosynthetic response may be critical to detect food-borne pathogens on leafy greens. MSI demonstrated that plant stress was detectable and proportional to the bacterial inoculation rate on plants. Our research may lead to implementation of better strategies and technology to increase yield and reduce risks associated with contamination of foodborne bacterial pathogens.

Research – Severe Streptococcus equi Subspecies zooepidemicus Outbreak from Unpasteurized Dairy Product Consumption, Italy

CDC

Abstract

During November 2021–May 2022, we identified 37 clinical cases of Streptococcus equi subspecies zooepidemicus infections in central Italy. Epidemiologic investigations and whole-genome sequencing showed unpasteurized fresh dairy products were the outbreak source. Early diagnosis by using sequencing technology prevented the spread of life-threatening S. equi subsp. zooepidemicus infections.

Streptococcus equi subspecies zooepidemicus is a β-hemolytic streptococcus expressing Lancefield group C antigen and is 1 of 3 S. equi subspecies. S. equi subsp. zooepidemicus is an opportunistic pathogen that can infect domestic animals, pets, and wildlife (1–6). Sporadic human cases have been reported (7), characterized by clinical manifestations that vary from meningitis to sepsis. Human infection generally occurs through direct contact with infected animals or by consumption of contaminated unpasteurized milk or other dairy products (8–10). We report a large S. equi subsp. zooepidemicus outbreak in Italy.
