Research – Antimicrobial Activity of Ohelo Berry (Vaccinium calycinum) Juice against Listeria monocytogenes and Its Potential for Milk Preservation

MDPI

Listeria monocytogenes is a foodborne pathogen and causes illnesses with a high mortality rate in susceptible populations. Several dairy-related outbreaks have been attributed to contamination by L. monocytogenes, which requires antimicrobial interventions to enhance the safety of these products. This study aimed to determine the antimicrobial activity of the ohelo berry (Vaccinium calycinum), a Hawaiian wild relative of cranberry, against L. monocytogenes in culture media and milk products. The effect of ohelo berry juice at its sub-inhibitory concentrations on the physicochemical properties, biofilm formation, and gene expression of L. monocytogenes was also investigated. The minimum inhibitory concentration of ohelo berry juice against L. monocytogenes was 12.5%. The sub-inhibitory concentration of ohelo berry juice (6.25%) significantly increased the auto-aggregation and decreased the hydrophobicity, swimming motility, swarming motility, and biofilm formation capability of L. monocytogenes. The relative expression of genes for motility (flaA), biofilm formation and disinfectant resistance (sigB), invasion (iap), listeriolysin (hly), and phospholipase (plcA) was significantly downregulated in L. monocytogenes treated by the 6.25% juice. L. monocytogenes was significantly inhibited in whole and skim milk supplemented with 50% ohelo berry juice, regardless of the fat content. These findings highlight the potential of ohelo berry as a natural preservative and functional food to prevent L. monocytogenes infection.

Research – Dietary Inclusion of a Saccharomyces cerevisiae-Derived Postbiotic Is Associated with Lower Salmonella enterica Burden in Broiler Chickens on a Commercial Farm in Honduras

MDPI

Postbiotic feed additives may aid foodborne pathogen reduction during poultry rearing. The study objective was to evaluate a postbiotic additive in parallel to an industry control diet and the subsequent associated burden of Salmonella enterica on a single, commercial broiler farm in Honduras. Twelve houses were matched and assigned the standard diet (CON) or standard diet plus postbiotic (SCFP). New litter was placed in each house and retained across flock cycles with sampling prior to each chick placement and three consecutive rearing cycles. At ~33–34 days, 25 ceca were collected on-farm from each house, treatment, and cycle. Salmonella prevalence in litter for CON (30.6%) and SCFP (27.8%) were equivalent; however, Salmonella load within positive samples was lower (p = 0.04) for SCFP (3.81 log10 MPN/swab) compared to CON (5.53 log10 MPN/swab). Cecal prevalence of Salmonella was lower (p = 0.0006) in broilers fed SCFP (3.4%) compared to CON (12.2%). Salmonella load within positive ceca were numerically reduced (p = 0.121) by 1.45 log10 MPN/g for SCFP (2.41 log10 MPN/g) over CON (3.86 log10 MPN/g). Estimated burden was lower (p = 0.003) for SCFP flocks (3.80 log10 MPN) compared to CON (7.31 log10 MPN). These data demonstrate the preharvest intervention potential of postbiotics to reduce Salmonella enterica in broiler chickens. View Full-Text

Research – Finland and Switzerland see food recalls rise

Food Safety News

Food recalls increased for the sixth year in a row in 2021, according to the Finnish Food Agency (Ruokavirasto).

The amount of alerts passed 300 for the first time and were mainly because of microbiological contamination, allergens and pesticide residues. The 309 recall total was 42 more than in 2020.

Microbiological concerns such as Salmonella, Listeria and other bacteria caused 49 recalls, which is up 9 percent compared to the previous year. Salmonella was behind 26 recalls in products including fresh herbs and eggs while Listeria in items such as cheese caused five recalls.

Switzerland has revealed the number of recalls and public warnings issued in 2020.

The Federal Food Safety and Veterinary Office (FSVO) published 28 public warnings and 49 recalls for food. Warnings were most often because of pesticide residues, pathogenic microorganisms or allergens. Recalls were mainly because of pesticide residues, foreign bodies or mycotoxins.

At the beginning of 2020, Swiss authorities were informed about norovirus in oysters and mussels from France. Eight other EU countries received mussels from affected French production sites. In Switzerland, illnesses occurred following consumption of these products.

A total of 241 RASFF notifications concerned Switzerland and 62 were issued by the country.

For the 241 notifications, almost a third related to pesticide residues and 27 were because of microbial contamination. Of notices raised by Switzerland, 15 were because of mycotoxins and pesticide residues caused eight. Fifteen products from Switzerland were the subject of a RASFF post. The most frequent hazard was microbial contamination with four notifications.

USA – FDA Warning Letter – Greenhead Lobster Products LLC

FDA

The United States Food and Drug Administration (FDA) inspected your ready-to-eat (RTE) seafood processing facility located at 122 Heritage Park Rd., Bucksport, ME 04416-4603, on September 21, 22, 23, 27, and 30, and October 6, 2021. During our inspection we collected environmental samples (i.e., swabs) from various areas in your facility, including areas that are near food during processing operations and your food-contact surfaces. FDA laboratory analyses of environmental samples found the presence of Listeria monocytogenes (L. monocytogenes), a human pathogen, in your facility. Additionally, FDA found serious violations of the Seafood Hazard Analysis and Critical Control Point (HACCP) regulation, Title 21, Code of Federal Regulations (CFR), Part 123 (21 CFR Part 123).

In accordance with 21 CFR 123.6(g), failure of a processor of fish or fishery products to have and implement a HACCP plan that complies with this section or otherwise operate in accordance with the requirements of Part 123, renders the fish or fishery products adulterated within the meaning of Section 402(a)(4) of the Federal Food, Drug, and Cosmetic Act (the Act), 21 U.S.C. § 342(a)(4). Based on our inspectional results, including review of FDA’s environmental testing and your HACCP plan, we have determined that your RTE cooked lobster products are adulterated within the meaning of section 402(a)(4) of the Act, 21 U.S.C. § 342(a)(4), in that they have been prepared, packed, or held under insanitary conditions whereby they may have become contaminated with filth or rendered injurious to health. You may find the Act, the seafood HACCP regulation, and the 4th Edition of the Fish and Fisheries Products Hazards and Controls Guidance through links in FDA’s home page at www.fda.gov.External Link Disclaimer

At the conclusion of the inspection, the FDA investigators issued your facility a Form FDA 483, Inspectional Observations. You provided responses to the FDA Form 483 and FDA’s environmental sample findings via email on October 7 and 13, 2021, which included corrective actions taken by your firm. We have reviewed the documentation and continue to have serious concerns with your current HACCP programs as further described in this letter.

France – Child in France dies of E.coli infection as outbreak monitored

Connexion France

Health authorities have not released more information about the child that has died, but 13 other cases in children have prompted a nationwide investigation into the possible source.

Health authorities in France are monitoring an outbreak of E.coli following the death of a child and the detection of 13 cases across the country.

Santé publique France (SPF) issued the alert after the contaminations were first noticed at the beginning of February. The authority has confirmed that one child has died, but has not released information of the date of the death, location, or the age of the child.

Among children aged 1-15, there have been:

  • 5 cases reported in Nouvelle-Aquitaine
  • 3 cases in Hauts-de-France
  • 3 cases in Ile-de-France
  • 1 case in Brittany
  • 1 case in Pays de la Loire.

All of the children were affected by haemolytic uraemic syndrome (HUS), a potentially serious disease in young children, most often caused by food.

It is usually characterised by severe diarrhoea, which can lead to acute renal failure, and usually caused by bacteria belonging to the Escherichia coli (E.coli) family.

The SPF inquiry is looking into every report of similar cases as they are reported to paediatric units, and is aiming to “identify a common source of contamination and put appropriate measures in place”.

It has “not excluded any possibility at this stage”, it said.

Research – Pathogenesis of the Pseudomonas aeruginosa Biofilm: A Review

MDPI

Pseudomonas aeruginosa is associated with several human infections, mainly related to healthcare services. In the hospital, it is associated with resistance to several antibiotics, which poses a great challenge to therapy. However, one of the biggest challenges in treating P. aeruginosa infections is that related to biofilms. The complex structure of the P. aeruginosa biofilm contributes an additional factor to the pathogenicity of this microorganism, leading to therapeutic failure, in addition to escape from the immune system, and generating chronic infections that are difficult to eradicate. In this review, we address several molecular aspects of the pathogenicity of P. aeruginosa biofilms. View Full-Text
