USDA-FSIS Surveys Salmonella Rates in NRTE Breaded Stuffed Chicken Products

Food Safety.Com

As part of an effort to reduce cases of salmonellosis attributable to poultry products, the U.S. Department of Agriculture’s Food Safety and Inspection Service (USDA’s FSIS) conducted a study with the Food Emergency Response Network (FERN) laboratories to gather data on not-ready-to-eat (NRTE) breaded stuffed chicken products purchased at retail stores. The release of the survey results follows FSIS’ April 2023 proposed determination to declare Salmonella an adulterant in breaded stuffed raw chicken products.

The survey was intended to gather information on the positive rate of Salmonella in NRTE breaded stuffed chicken products and any differences in laboratory methods used.

Through FERN, 11 geographically dispersed state labs participated in the study. From July 1, 2022—September 30, 2022, the labs purchased locally available NRTE breaded stuffed chicken products at retail stores (approximately 15 samples per month for each product) and tested them for the presence of Salmonella and indicator organisms.

In total, 58 of the 487 samples tested were positive for the presence of Salmonella. A noticeable difference in positivity rates was seen between laboratories that ran methods the same as FSIS (36 of 135, or 27 percent) using larger test portions and laboratories that ran methods different from FSIS (22 of 352, or 6 percent) using smaller test portions. Small amounts of Salmonella present in the product or uneven distribution of Salmonella contamination could account for the lower positivity rates when smaller sample portions were tested.

Total aerobic counts were similar across products tested. Whole genome sequencing detected S. Enteritidis (18 of 58), S. Infantis (22 of 58), S. Kentucky (15 of 58) and S. Typhimurium (3 of 58).

USA – Celebrate Your Fourth of July Without Foodborne Illness

USDA

The Fourth of July is a time of celebration, family and of course cookouts. Cooking safely is in your hands and doing so can help keep your family healthy this Independence Day. Control the transfer of bacteria by thoroughly washing your hands before and after touching raw meat, poultry and seafood.

The USDA recommends the following food safety tips for grilling:

Preheat your grill and scrub the grate with a long-handled brush once the grill has fully preheated. Remnants from the last grill session should scrape off.
Remove the meat, poultry or seafood from its container and place on the grill at a safe distance apart. Discard any marinade used to prepare your meat, poultry or seafood.
When grilling your foods, make sure you’ve destroyed dangerous bacteria by cooking to the proper internal temperature.

Beef, pork, lamb: 145 F with a 3-minute rest.
Ground meats: 160 F.
All poultry (whole or ground): 165 F.
Fish (whole or filet): 145 F.

You can’t tell by looking at food whether it is done. Always use a food thermometer to check the internal temperature of your food to determine if it is safe to eat. The thermometer should be inserted into the thickest part of the meat and poultry, through the side of burgers and thin filets of fish, for the most accurate temperature reading.

Make sure to pack up any leftovers and refrigerate them within two hours. In hot weather (above 90 F), refrigerate within one hour.

For more food safety information, call the USDA Meat and Poultry Hotline at 1-888-MPHotline (1-888-674-6854) from 10 a.m. to 6 p.m. Eastern Time, Monday through Friday, in English or Spanish, or email mphotline@usda.gov. Consumers can also chat live at ask.usda.gov.

UK retailers share Campylobacter in chicken results

Food Safety News

Supermarkets in the United Kingdom have reported their Campylobacter in chicken results for late 2022.

The Food Standards Agency (FSA) maximum target level is up to 7 percent of birds with more than 1,000 colony-forming units per gram (CFU/g) of Campylobacter.

Data from the retailers covers October to December 2022 on high findings of Campylobacter in fresh, shop-bought, UK-produced chickens.

Results at Waitrose, Morrisons and Lidl went up while Marks and Spencer, Aldi, Asda, and Sainsbury’s recorded lower levels of contamination than the previous quarter. Figures for Co-op stayed the same.

Campylobacter is the most common cause of bacterial food poisoning in the UK and the dose needed to make people sick can be as low as a few hundred cells.

Tesco has stopped publishing data as it has changed the way it monitors the pathogen in chicken so findings are not comparable with other retailers.

Armenian Poultry Producer “Mum” on Salmonella Outbreak

HETQ

A leading poultry producer in Armenia remains silent on why salmonella was found in its frozen chickens sold on supermarket shelves.

Hetq, in conjunction with Armenia’s Food Safety Inspectorate (FSI) sent frozen chickens sold by Getamej and the Arax Poultry Factory for lab testing and found the bacteria.

The FSI, on June 15, stated it shut done the Arax Poultry Plant and banned the sale of Getamej products.

Hetq attempted to contact the Arax Poultry Plant to see if the bacteria has killed off some of their birds.

For weeks, company representatives never responded to our inquiries after promising to do so.

Today, the company contacted Hetq, saying they will get back to us when necessary.

Wales – E.coli cases being investigated at North Wales school

Daily Post

A North Wales school will be closed to nursery and reception-aged children after two children were diagnosed with an E.coli infection. Children who have been identified as close contacts to the cases are being asked to provide a stool sample as Public Health Wales investigate the infection.

Public Health Wales has confirmed that it is investigating two confirmed cases of E.coli in two children who attend Ysgol Pen Barras in Ruthin. The school will be closed on Monday and Tuesday.

Research – Strategies to Reduce Clostridium botulinum Risk in Fresh-Cut Produce

food safety.com

The risks associated with Clostridium botulinum and low-acid canned foods, meats, seafood, and temperature-abused foods are generally well-established. However, there has been increasing consideration toward C. botulinum and its potential as a pathogen of concern for fresh-cut vegetables, fruits, and mushrooms.

For an industry segment beleaguered by recent outbreaks of Shiga toxin-producing Escherichia coliSalmonella enterica, and Listeria monocytogenes, consideration of a bacterial pathogen with vastly different growth characteristics—one that is less traditionally associated with fresh produce—may seem burdensome. However, recent incidences of C. botulinum in packaged mushrooms,1 increased characterization of the growth conditions required by nonproteolytic C. botulinum, widespread industry adoption of modified atmosphere packaging (MAP), and even increasing fuel costs may necessitate a second look at this pathogen’s association with fresh produce.

Research – New insights on bacteria that causes food poisoning

Science Daily

A joint research group has clarified how pathogenic genes in some Providencia spp., which have gained attention as causative agents of food poisoning as well as enterohemorrhagic Escherichia coli. O157 and Salmonella, are transferred within bacterial cells. Their findings are expected to provide new insights into the identification of infection routes of Providencia spp. and the establishment of preventive methods for food poisoning.

Jordan – Six suspected food poisoning cases in Mafraq

Roya News

There are six suspected food poisoning cases in Mafraq, allegedly in relation to a takeaway restaurant, according to a medical source Thursday.

The source told Roya that the people arrived at the Talal Military Hospital, saying that they had eaten food from a restaurant and developed symptoms of food poisoning.

Another source confirmed that a restaurant in the governorate was suspended from operating due to violations.

The source added that if it was found that the food poisoning was caused by the restaurant’s food, legal measures will be taken against the concerned management.
