Research- Fish, Tilapia, and Shigellosis: A review

AJAR

Foodborne diseases are considered a relevant issue in health around the world due to their incidence, mortality and negative effects on the economic and productive sector. Fish is considered a food of high nutritional quality, being of global production, distribution and commercialization mainly for human consumption. Among the fish worldwide obtained from capture fisheries and mainly aquaculture for human consumption is Tilapia, due to the adaptability of this fish under cultivation conditions in addition to the fact that its meat is of quality and accessible economic value. Fish due to its composition, is highly susceptible to deterioration and contamination by different hazards throughout the food chain, putting the safety of products and public health at risk. Shigellosis is among the diseases that may be contracted from the consumption of food contaminated by bacteria of the genus Shigella spp.; food contamination is mainly related to inadequate or non-hygienic conditions and practices in the production, processing and handling of food. Therefore, the purpose of this review is to provide a general perspective of foodborne diseases, especially shigellosis, causal agents, conditioning factors, related foods such as fish, as well as control and preventive actions in order to protect the food safety and public health.

USA – Outbreak sickens dozens; no cause found; investigation closed

Food Safety News

The FDA has concluded its investigation of an outbreak of Salmonella Miami with a one-word public statement: closed.

A source for the pathogen, which has sickened at least 64 people, remains unknown, according to the Food and Drug Administration. In its weekly outbreak update, the agency ended the investigation with as little fanfare as it began it. The FDA’s initial announcement was a one-line entry on its weekly outbreak update table.

UK – Sainsbury’s Campylobacter rates in chicken hit FSA threshold

Food Safety News

Campylobacter kswfoodworld

Sainsbury’s has recorded the worst Campylobacter in chicken results for the final three months of 2020 closely followed by Tesco.

Figures come from the top nine retailers in the United Kingdom publishing the latest quarter of testing findings.

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

Sainsbury’s reported 7 percent of chickens sampled were above 1,000 CFU/g in the fourth quarter of 2020 (4Q), compared to 2 percent in 3Q, slightly more than 4 percent in 2Q and about 3 percent in 1Q 2020.

Denmark – 33 sick, 19 hospitalized and 3 dead: REMEMBER herbal medicine linked to severe Salmonella outbreak in Denmark

SSI

Salmonella has been found in HUSK Psyllium seed husks, “capsules herbal medicine”. Orkla Care A / S has recalled several products and the authorities are now strongly encouraging people to check whether they have any of the affected HUSK products.

The salmonella outbreak, which the Statens Serum Institut sent out a news item about last week , is becoming increasingly extensive. In the meantime, the type of salmonella in question has been detected in a number of other people.

A total of 33 people aged 2-92 years have been diagnosed with the same type of salmonella. Several are seriously affected. 19 people have so far been hospitalized, and 3 people where the salmonella in question has been detected have died.

“It is a serious and large outbreak with many sick and both hospitalized and deaths. Therefore, we would like to encourage everyone who has HUSK products at home to check if they have any of the affected products “, says epidemiologist Luise Müller from the Statens Serum Institut (SSI)

Found salmonella in herbal medicine

SSI, together with the Danish Medicines Agency, the Danish Veterinary and Food Administration and the DTU Food Institute, has investigated the salmonella outbreak.

Common to the patients was that they had eaten HUSK Psyllium seed husks, herbal medicine, capsules ”. A comparison with healthy controls showed that the sick had eaten HUSK products to a much greater extent than the controls.

The Danish Veterinary and Food Administration therefore obtained the product from two patients’ homes and was able to prove that there was salmonella in it. Several HUSK products were subsequently recalled.

“This is the first time that we have been able to identify an herbal medicine as the cause of a salmonella outbreak. Those who take this product are often people who already have stomach problems. I am therefore concerned that the salmonella infection will not be detected because the individuals or their doctor believe that the symptoms of the salmonella infection stem from their existing stomach problems, ”says Luise Müller.

What to check?

You must check whether you have:

• Herbal remedy Psyllium husks, capsules

• The dietary supplement REMEMBER Psyllium Stomach Balance Basic, capsules

Find photos and batch numbers on the recalled products here

If you have the product at home, check whether it originates from one of the batches that Orkla Care A / S has withdrawn. The batch number is always printed on the outside of the plastic container.

If you have products from those batches, you should either throw them out or. deliver them back to the store where they were purchased.

What should you do if you have eaten one of the products?

Even if you should have eaten the HUSK Psyllium seed pods, herbal medicine, capsules or HUSK Psyllium Stomach Balance supplements, capsules, the risk of being infected with salmonella is considered too small.

Most often, the symptoms of salmonella are mild and go away on their own. If you get persistent symptoms or have doubts, you can consult your own doctor.

Research – What lives inside the chicken gut?

Phys Org

In a recently published study, investigators from Norwich and Surrey have more than doubled the number of microbial species known to live in the chicken gut. As the health and wealth of humans is tied to the health and productivity of chickens, this lays down a key resource for all future studies on the gut microbiome of this important food animal.

With three times as many chickens as people on our planet, this ubiquitous food animal underpins human nutrition and health across the globe—whether through subsistence farming or intensive production, chickens supply more of our food than any other animal. Chicken meat is surging in popularity as a lower-carbon alternative to meat from other livestock, whilst eggs remain an important and affordable source of nutrition worldwide. However, poultry are also a source of antimicrobial resistance and of pathogens such as Campylobacter, Salmonella and E. coli that threaten human health.
