Research – Application of natural plant extracts as colorants, preservatives, and anti-listerial agents in processed fish products

Wiley Online Library

Abstract

The anti-listerial activity of various plant extracts was investigated, qualitatively and quantitatively against Listeria monocytogenes strains. The extracts of Punica granatum peels (PPE) and Hibiscus sabdariffa calyxes (RCE) exhibited the most potent antibacterial activity. The application of PPE and RCE, as colorant, preservative, and antimicrobial agents, was conducted for the manufacturing of fish products (burger and surimi). The two extracts could effectively enhance the microbial, sensory, and shelf life attributes of prepared fish products. The combination of the extracts at their inhibitory concentrations lead to complete inhibition of inoculated L. monocytogenes cells, enhancing the sensory attributes of treated fish products and increasing panelists’ preference.

Practical applications

Foodborne pathogens’ transmission via fish products, for example, L. monocytogenes, is hazardous and must be overcome efficiently and safely. The substitution of synthetic and chemical food additives and preservatives with natural agents is a general request from all. Results of study supported the practical application of powerful anti-listerial plant extracts, for example, pomegranate peels and rosella calyxes, for the control of L. monocytogenes, coloring and improving sensorial attributes of processed fish products, burger and surimi.

USA- A woman died after contracting flesh-eating bacteria from eating raw oysters — here’s why a food poisoning expert avoids the food

Business Insider 

A Texan woman has died after contracting a flesh-eating bacteria after eating raw oysters on a trip to the the Louisiana coast.

Jeanette LeBlanc died after a three-week battle with vibriosis, an illness typically caused by eating raw seafood, CBS reported. 

After shucking and eating roughly two dozen raw oysters with her wife and a friend, LeBlanc began having respiratory distress and a rash, which she and her wife initially assumed were signs of an allergic reaction. But, when she went to the hospital, doctors said she had been infected by Vibrio bacteria.

“It’s a flesh-eating bacteria,” her wife, Vicki Bergquist, told local news station KLFY. “She had severe wounds on her legs from that bacteria.”

The CDC estimates that vibriosis causes 80,000 illnesses each year in the US, most caused by consuming contaminated food. While most people recover from the infection, one variant — the Vibrio vulnificus infection — is often deadly. One in four infected people die, often within just a day or two of becoming ill.

The Seremi de Salud Bío Bío confirmed 174 cases of salmonella making it the largest outbreak of the last 4 years nationwide and the largest recorded in the Bío Bío Region.

The outbreak has affected people ages 1 to 91 and 25 people required hospitalization for their illness.

Health officials are investigating whether raw egg was the source of the salmonella and the strain is being identified. In addition, since the local “Dulce y Salado” was closed last week, they don’t expect any significant rise in cases.

Research – Detection of foodborne viruses in ready-to-eat meat products and meat processing plants

wiley online library

Abstract

Several studies have confirmed the presence of foodborne viruses in different food products throughout the world. There is accumulating data suggesting that the economic burden of foodborne viral infections is rising, making the understanding and monitoring of their prevalence a necessity, for the modern food industry. The objective of this study was to examine ready-to-eat meat products and environmental samples originated from meat processing plants in Cyprus, for four foodborne viruses: norovirus (NoV GGI, NoV GII), rotavirus, hepatitis A virus, and hepatitis E virus. A total of 48 swab samples and 42 different pork meat products from two plants were analyzed in parallel. The reverse transcription real-time polymerase chain reaction revealed two swab samples from the same plant positive for norovirus GGI. The detection of norovirus on a slicer machine and on the hands of a worker, suggest that foodborne viruses can be present in meat processing environments.

Practical applications

There is an increasing need to better understand the prevalence of foodborne viruses in the environment and food, given the rise of viral foodborne outbreaks throughout the world, as reported by World Health Organization. Meat products form an important exposure vehicle to humans either directly, through the consumption of raw products, or as a result of cross-contamination in food processing plants. This is the first report in Cyprus illustrating the presence of foodborne viruses in meat processing plants and the possible impact in public health, through the consumption of ready-to-eat meat products.

Denmark – Chicken still main source of Campylobacter infections in Denmark

 

Poultry Med 

Almost half of all campylobacter infections in Denmark are caused by consumption of domestic chicken meat. Campylobacter is the leading cause of foodborne infections in Denmark. A total of 4,677 campylobacter infections were registered in 2016, but these are only the tip of the iceberg: estimates suggest that for every registered case of campylobacter, another 12 cases go unreported.
Researchers from the National Food Institute have produced a report for the Danish Veterinary and Food Administration, which show what proportion of cases acquired in Denmark can be attributed to eight different food and environmental sources.
Consumption of domestic chicken meat continues to be the most important source accounting for 46% of campylobacter infections acquired in Denmark, followed by cattle (beef, milk or direct contact), which accounts for 19% of cases and consumption of imported chicken meat (9%). Contact with dogs and exposure to contaminated seawater each account for approximately 4% of infections.
