MDPI

Abstract

Campylobacter is a leading foodborne pathogen, and poultry are a major vehicle for infection. Houseflies play important roles in colonization of broiler flocks with Campylobacter but comparable information for turkey farms is limited. Here, we investigated houseflies as potential vectors for Campylobacter in 28 commercial turkey flocks. We characterized species, genotypes, and the antimicrobial resistance (AMR) profiles of Campylobacter from turkey feces and houseflies in the same turkey house. Of the 28 flocks, 25 yielded Campylobacter from turkey droppings and houseflies, with an average of 6.25 and 3.11 Campylobacter log CFU/g feces and log CFU/fly, respectively. Three flocks were negative for Campylobacter both in turkey feces and in houseflies. Both C. coli and C. jejuni were detected in turkey feces and houseflies, with C. coli more likely to be recovered from houseflies than feces. Determination of Campylobacter species, genotypes, and AMR profiles revealed up to six different strains in houseflies from a single house, including multidrug-resistant strains. For the predominant strain types, presence in houseflies was predictive of presence in feces, and vice versa. These findings suggest that houseflies may serve as vehicles for dissemination of Campylobacter, including multidrug-resistant strains, within a turkey house, and potentially between different turkey houses and farms in the same region.

New Indian Express

GUNTUR: As many as 130 students fell sick  after consuming food at Gurukul school in Ramakrishnapuram in Palnadu district on Monday. Out of these students, 60 were admitted to hospital due to suspected food poisoning after they complained of vomiting and diarrhoea. As many as 650 students are studying at the Gurukul.

According to sources, a few students complained of stomach pain and nausea in the morning hours of Monday. The health officer at the school gave them the required medicines. However, the situation turned worse when several other students too took ill with similar symptoms. Later, they shifted the students to the Sattenapalli area hospital.

Research – Mycotoxin survey: Watch out for exposure from dirty maize

Posted on February 1, 2023 by | Leave a comment

Irish Examiner

If you’re feeding maize, you likely have a mycotoxin problem on your farm, delegates at a recent ruminant nutrition were told.

Breaking down the results of this year’s mycotoxin survey, Laura Quinn, Ruminant Technical Species Expert at DSM, said: “When plants get stressed – whether that be drought, weather-related or disease – they can be vulnerable to being attacked by fungi, and mycotoxins are toxic secondary metabolites which are released by the fungi.

“They are in almost all agricultural commodities worldwide. They are very stable, can persist in heat and are resistant to any processing at feed mills.”

Biomin and DSM have run the survey since 2004.

The firm analyses over 20,000 samples a year and offers localised predictions for mycotoxins based on weather patterns.

“Mycotoxins are anti-protozoal, anti-bacterial and anti-fungal, which is great for disinfectant, but considering in the rumen we are trying to use these to break down feed materials to produce milk, we don’t want them having that effect in the cow.”

In dairy animals, mycotoxins have been linked with reduced feed intake, lower milk yields, liver inflammation, lower vaccine efficacy, and lower fatty acid production, among other production and health issues.

There are currently more than 1,000 mycotoxins identified, with more being discovered by scientists all the time.

Ireland – More than 7,000 birds on eight poultry farms in Ireland to be culled due to salmonella outbreak

Posted on February 1, 2023 by | Leave a comment

Irish Times

A large salmonella outbreak on eight poultry farms around the country has resulted in more than 7,000 birds having to be culled to ensure potentially-infected chicken products do not enter the food chain.

Due to the risk to human health from the bacteria, restrictions have been applied in the vicinity of the farms, most of which are in Co Cavan.

The Food Safety Authority of Ireland (FSAI) is working with the Department of Agriculture, Food and the Marine (DAFM) in an effort to curb the outbreak and to determine its cause.

The FSAI has confirmed that incidences of salmonella infection in broiler flocks were linked to a raw-chicken food recall it issued last week, when some poultry products were removed from supermarket shelves.

USA – Conagra Brands Recalls Canned Meat and Poultry Products Due to Possible Packaging Defect

Posted on February 1, 2023 by | Leave a comment

FSIS USDA

WASHINGTON, Jan. 31, 2023 – Conagra Brands, Inc., a Fort Madison, Iowa establishment, is recalling approximately 2,581,816 pounds of canned meat and poultry products due to a packaging defect that may cause the products to become contaminated without showing any outward signs of contamination, the U.S. Department of Agriculture’s Food Safety and Inspection Service (FSIS) announced today.

The meat and poultry products were produced between December 12, 2022, and January 13, 2023. The following products are subject to recall: [view spreadsheet] [view labels].

The products subject to recall bear establishment number “P4247” on the product cans. These items were shipped to retail locations nationwide.

The problem was discovered when the establishment notified FSIS after observing spoiled and/or leaking cans from multiple production dates at the establishment’s warehouse.

Subsequent investigation by the establishment determined that the cans subject to recall may have been damaged in a manner that is not readily apparent to consumers, which may allow foodborne pathogens to enter the cans.

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.

Research – How Does Hepatitis A Spread Through Food?

Posted on January 31, 2023 by | Leave a comment

Food Poisoning News

In a developed country such as the United States, outbreaks of Hepatitis A (HAV) from contaminated food are not common but are still possible and have occurred in the past. Some outbreaks have been linked to thousands of cases. It can be difficult, however, to pinpoint the source of infection because of the late onset of symptoms especially when the victims are geographically scattered. A food product can become contaminated at any step during the process of harvesting, distribution, preparation, etc…  When the problem occurs at one of the early stages, say during production, this can lead to a wide-spread outbreak, such as recent outbreaks of HAV linked to imported pomegranates or HAV linked to imported strawberries.

However, most recorded HAV outbreaks in the United States have occurred at the point of sale when food is handled and served in a restaurant. While most food handlers with HAV do not transmit the virus because they practice proper personal hygiene, all an infected person has to do to spread the virus is touch food after failing to wash their hands. These “establishment” HAV outbreaks are usually in a single geographic location tied to a particular restaurant, like the relatively recent Burger King or Famous Anthony’s outbreaks.

Irish officials search for the source of the Salmonella outbreak

Posted on January 31, 2023 by | Leave a comment

Food Safety News

Health officials in the Republic of Ireland are investigating a Salmonella outbreak that has sickened more than 20 people.

The number of laboratory-confirmed cases associated with the epidemic is 26 and people fell ill between Nov. 30 and Dec. 25, 2022.

Patients range in age from 10 to 91 years old; 14 are male and 12 are female, according to the Health Service Executive (HSE).

The Salmonella Typhimurium outbreak was identified through routine whole genome sequencing.

The outbreak control team includes the HSE Health Protection Surveillance Centre (HPSC), regional departments of public health, HSE environmental health officers, the National Salmonella, Shigella, and Listeria Reference Laboratory, the Food Safety Authority of Ireland (FSAI), the Department of Agriculture Fisheries and the Marine (DAFM), and colleagues from Northern Ireland.

The source of the infection remains under investigation. Officials would not say if the outbreak was linked to a recall of raw chicken products in late January.
