USA – FDA finds Salmonella in three lots of Darwin’s raw dog food; cautions pet owners

Food Safety News

The U.S. Food and Drug Administrations (FDA) cautioned pet owners not to feed certain Darwin’s Natural Pet Products raw dog foods after finding Salmonella in the products.

FDA collected and analyzed unopened packages from the products in response to a consumer complaint.

The products were manufactured by Arrow Reliance, Inc. (Arrow), a company based in Tukwila, Washington and doing business as Darwin’s Natural Pet Products.

The products that are affected by FDA’s alert to pet owners are:

  • Darwin’s Natural Pet Products Natural Selections Chicken Recipe with Organic Vegetables for Dogs: 5309(11)181019, manufactured on October 19, 2018
  • Darwin’s Natural Pet Products Natural Selections Chicken Recipe with Organic Vegetables for Dogs: 5375(11)181106, manufactured on November 11, 2018
  • Darwin’s Natural Pet Products Natural Selections Turkey Recipe with Organic Vegetables for Dogs: 5339(11)181026, manufactured on October 26, 2018

Arrow has taken steps to remove these products from the marketplace, but has not issued a public notification, according to the FDA. The agency is concerned that the company’s customer notifications may not be effective, and is working with Arrow on recalling the remaining products from these lots.

In a statement released on its website today, Darwin’s expressed its disappointment in FDA’s decision to issue a public warning. The company also asserted its belief that its products do not pose any danger to either humans or pets, and stated that it had received no medical reports of illnesses attributable to these meals.

Animals infected with Salmonella may suffer symptoms that include vomiting, diarrhea (sometimes bloody), fever, loss of appetite and decreased level of activity. An infected animal may not exhibit any symptoms but may still shed the bacteria in its feces, passing the infection to human companions.

Salmonella can cause illness and death in humans and in animals. People infected with Salmonella may develop diarrhea, fever and abdominal cramps. The elderly, the very young, and individuals with weak immune systems are more prone to suffering severe symptoms, including secondary infections in other organs.

Research – Influence of Antimicrobial Agents on the Thermal Sensitivity of Foodborne Pathogens: A Review

Journal of Food Protection

Consumers are driving food production toward the use of more organic antimicrobial agents such as essential oils (EOs) by demanding more natural and clean-label food products. Due to the strong aromatic and flavor properties of EOs, their use is often precluded, or limited to concentrations below the flavor threshold. However, adding EOs at concentrations this low often renders their biocidal activity ineffective. An opportunity exists for low concentrations of EO antimicrobial agents to be combined with mild heating (e.g., 42 to 55°C) for short treatment times to use the hurdle concept for additive or synergistic effects on foodborne pathogens such as Escherichia coli O157:H7, Salmonella, or Listeria monocytogenes; norovirus; and surrogate organisms. In some cases, especially with fruit juices, this intervention combination is described as antimicrobial-assisted pasteurization. Used below the organoleptic quality threshold, EOs, which otherwise would have little effect on the inactivation of foodborne pathogens, are effective antimicrobial agents when used in conjunction with mild thermal processes. Thermal processes combined with antimicrobial agents can be used for processing liquids, eggs, juices, drinks, and fresh produce. This review highlights research literature where antimicrobial agents and mild heating have been combined to increase the inactivation of foodborne pathogen populations. Commodities and testing substrates reviewed include buffers and nutrient broths, juices, liquid egg, mangoes, cut lettuce, cut and shredded cabbage, shredded carrot, baby spinach leaves, and salsa. Opportunities exist for the application of this hurdle technology to a whole array of food products, which could benefit from pathogen reduction or elimination, and to prevention of aqueous cross-contamination and/or internalization during the washing of fresh produce.

Europe – ECDC – Multi-country cluster of Listeria monocytogenes ST1247 in five EU countries

ECDC

CDC has identified a microbiological link between an outbreak of nine Listeria monocytogenes ST1247 cases in Denmark and nine additional cases reported between 2014 and 2018 in Estonia (2 cases) Finland (2), France (1) and Sweden (4).

ECDC has identified a microbiological link between an outbreak of nine Listeria monocytogenes ST1247 cases in Denmark and nine additional cases reported between 2014 and 2018 in Estonia (2 cases) Finland (2), France (1) and Sweden (4).  In Denmark, the outbreak investigation is led by Statens Serum Institut (SSI), the Danish Veterinary and Food Administration and the DTU Food Institute.

Whole Genome Sequencing (WGS) analysis performed at the national level and by ECDC found all isolates from the 18 cases within two allelic differences from each other (core genome MLST using Moura scheme, 1540 of 1748 loci detected in all 18 isolates). The latest case was reported in Denmark in February 2019 (Figure 1).

A large-scale study led by ECDC on whole genome sequencing shows that most listeria outbreaks such as this one remain undetected. The study, published in 2018, suggests that more than half of the severe listeriosis cases in the European Union belong to clusters, many of which are not being picked up fast enough by the current surveillance system.

Listeria monocytogenes causes listeriosis, which primarily affects pregnant women, newborns, and adults with a weakened immune system. Listeriosis is a relatively rare but potentially severe food-borne disease that has been reported in increasing numbers in the EU/EEA countries since 2008. In 2016, 2 536 cases were reported, including 247 deaths.

A case of hepatitis A has been identified in a Frisch’s employee who worked in two of the restaurant’s locations: at 1228 Scioto Street in Urbana, Ohio, and at 1830 Bechtle Avenue in Springfield, Ohio. The Champaign Health District and the Clark County Combined Health District are working to vaccinate all restaurant employees.

Croatia -Croatia’s prime oyster farmers in alarm after Norovirus discovered

Infosurhoy

Oyster farming is the pride of this small town in the south of Croatia’s Adriatic Sea coast. But tasting the famed local delicacy may not be a good idea at the moment.

Authorities have detected norovirus, which causes diarrhea and vomiting, in parts of the Mali Ston bay—triggering shock and alarm among the breeders.

The traditional oyster-tasting feast in March has been canceled and fears are mounting of huge financial losses to the local community that harvests about 3 million oysters each year.

Experts are pointing their fingers at the outdated sewage system in the area that has seen a rise in the numbers of tourists flocking to Croatia’s stunning Adriatic coast.

“I am really sorry but people themselves are to blame that something like this happened,” explained Vlado Onofri from the Institute for Marine and Coastal Research in nearby Dubrovnik. “It’s something that has to be solved in the future.”

While some stomach bugs can be eliminated with cooking, norovirus survives at relatively high temperatures.

“The problem with oysters is that they are eaten raw,” Onofri said.

USA – Henry Avocado Recalls Whole Avocados Because Of Possible Health Risk – Listeria monocytogenes

FDA

Henry Avocado Corporation is voluntarily recalling California-grown whole avocados sold in bulk at retail stores because they have the potential to be contaminated with Listeria monocytogenes. Henry Avocado is issuing this voluntary recall out of an abundance of caution due to positive test results on environmental samples taken during a routine government inspection at its California packing facility. There are no reported illnesses associated with this recall.
