Iceland – Monitoring of Sunu 2019

Monitoring of Sunu 2019

Salmonella increased in poultry and pigs in 2019 compared to the year before there was an increase in salmonella infections in humans. The rapid increase in the illness caused by toxin producing E. coli (STEC) in people when the cycle of infection occurred last summer in the south . Food has published a report on the monitoring agents exhibit and antibiotic resistance in 2019 on the website of the Agency.

Sununu are diseases or pathogens (súnuvaldar) transmitted between humans and animals. Control of salmonella (Salmonella spp.) And Campylobacter (Campylobacter spp.) In the first stages of the food chain is powerful in the country and deliver increased consumer food safety. Other food-borne bacteria cause disease in people less than in the light of the very serious illnesses may include monitoring of the bacteria no less important.

The incidence of salmonella in poultry, the products of poultry and pigs increased from the previous year. The increase was due to repeated infected a few farms where it has been difficult to get rid of certain strains of bacteria. A similar increase was not found in people and it indicates that the monitoring of fire and slaughterhouses, in accordance with national programs, minimize the risk of contamination of poultry and pork in people. Whole Gene Research conducted in support that conclusion. While salmonella was found in one sample from the domestic pork market reminiscent of the constant need to be alert and to encourage proper treatment of food with consumers.

No significant changes were observed in the prevalence of Campylobacter in people or poultry and their products. Campylobacter was detected in three samples of frozen chicken meat market (2.1% of samples), samples from both domestic and foreign meat. In all cases, this was a very little bacterial contamination or below the detection limit (<10 cfu / g) counting method which dies Campylobacter mostly frozen.

The rapid increases in illness in people due to infections caused by toxin producing E. coli (STEC), which is explained primarily by a rally in the summer of 2019 in which 22 children and two adults became ill. So far, the incidence of this infection have been very low in people in this country, one to three cases a year. Epidemiological evidence regarding the cycle and screening conducted in 2018 and 2019 for STEC in meat market suggest that the bacteria are part of the microflora of Icelandic cattle and sheep. Research is needed, however, better prevalence of STEC in livestock and focus on preventive measures in slaughterhouses and meat processors to reduce the risk of spreading STEC in meat. Moreover, it must avoid the unclean artifacts present at the slaughterhouse.

Listeria (Listeria monocytogenes) found regularly in the known risks and production environment. That year the initiatives contained in the monitoring of food businesses that produce food ready for consumption, with an emphasis on smoke and buried fishery products, cheeses and meats. Go particular the sampling plan companies and their preventive measures against listeria.

We import control of animal products from third countries are regularly sampled for analysis of Salmonella, Listeria (L. monocytogenes) and E. coli. In 2019 were sampled consignments of eggs, cooked shrimp, mysudufti, meat products (prepared chicken dishes) and pet food. The samples were all negative.

Research – Contamination of spinach at germination: A route to persistence and environmental reintroduction by Salmonella

ACA

The effects of using contaminated seed and water on the persistence and internalization of Salmonella Newport in organic spinach cultivars- Lazio, Space, Emilia and Waitiki were studied. Seeds were contaminated by either immersing in a suspension of Salmonella and then sprouted or were sprouted in Salmonella contaminated water in the dark at 25 °C. After 5 days, germinated sprouts were analyzed for S. Newport population and internalization. Germinated sprouts were potted in soil and grown in a plant incubator for 4 weeks. Leaves, stems and roots were sampled for Salmonella population by plating on CHROMagar™. Plants surface-sterilized with chlorine were analyzed for internalized pathogen. Potting soil and water runoff were sampled for Salmonella after 4 weeks of plant growth. Contaminated seeds and irrigation water had S. Newport populations of 7.64±0.43 log CFU/g and 7.12±0.04 log CFU/ml, respectively. Sprouts germinated using contaminated water or seeds had S. Newport populations of 8.09±0.04 and 8.08±0.03 log CFU/g, respectively and had a Salmonella population that was significantly higher than other spinach tissues (P<0.05). Populations of S. Newport in leaves, stem and roots of spinach plants were as follows: contaminated seed- 2.82±1.69, 1.69±0.86, and 4.41±0.62 log CFU/ml; contaminated water- 3.56±0.90, 3.04±0.31, and 4.03±0.42 log CFU/ml of macerated tissue suspension, respectively. Internalization was observed in plants developing from contaminated seeds and in sprouts germinated using contaminated water. S. Newport populations of 2.82±0.70 log CFU/g and 1.76±0.46 log CFU/ml were recovered from soil and water runoff, respectively. The results indicate that contamination of spinach during germination can result in persistence, internalization and environmental reintroduction of Salmonella.

Research – Survival of Salmonella in Bathrooms and Toilets in Domestic Homes Following Salmonellosis

The survival and environmental spread of Salmonella bacteria from domestic toilets was examined in homes, where a family member had recently suffered an attack of salmonellosis. In four out of six households tested, Salmonella bacteria persisted in the biofilm material found under the recess of the toilet bowl rim which was difficult to remove with household toilet cleaners. In two homes Salmonella bacteria became incorporated into the scaly biofilm adhering to the toilet bowl surface below the water line. Salmonella enteritidis persisted in one toilet for 4 weeks after the diarrhoea had stopped, despite the use of cleaning fluids. Salmonellas were not isolated from normally dry areas such as, the toilet seat, the flush handle and door handle. Toilet seeding experiments were set up with Salmonella enteritidis PT4 to mimic environmental conditions associated with acute diarrhoea. Flushing the toilet resulted in contamination of the toilet seat and the toilet seat lid. In one out of three seedings, Salmonella bacteria were also isolated from an air sample taken immediately after flushing, indicating that airborne spread of the organism could contaminate surfaces in the bathroom. In the seeded toilet Salmonella bacteria were isolated from the biofilm in the toilet bowl below the waterline for up to 50 d after seeding, and also on one occasion from the bowl water. The results suggest that during diarrhoeal illness, there is considerable risk of spread of Salmonella infection to other family members via the environment, including contaminated hands and surfaces in the toilet area.

Research – Prevalence of E. coli , Salmonella , and Listeria spp. as potential pathogens: A comparative study for biofilm of sink drain environment

Wiley Online

Abstract

Since knowledge and understanding of waterborne pathogens and their diseases are well illuminated, a few research publications on the prevalence of pathogenic microorganisms in various household sink drain pipes are often not extensively examined. Therefore, this study aims to (a) assess and monitor the densities of the bacterial community in the different natural biofilm that grow on plastic pipelines, (b) to detect Escherichia coli Salmonella , and Listeria spp. from natural biofilm samples that are collected from the kitchen (= 30), bathroom (= 10), laboratories (= 13), and hospital (= 8) sink drainage pipes. Three bacterial species selected were assessed using a culture‐dependent approach followed by verification of isolates using both BIOLOG GEN III and polymerase chain reaction. The estimated number of each bacterium was 122 isolates, while 60, 20, 26, and 16 isolates were obtained from the natural biofilm samples, kitchen, bathroom, laboratories, and hospital, respectively. As for the tests, in all types of biofilm samples, the overall bacterial counts at low temperature (22°C) were higher than those at high temperature (37°C). Meanwhile, coli had the most significant number of bacterial microorganisms compared to the other two pathogens. Additionally, the most massive cell densities of coli Salmonella , and Listeria species were discovered in the biofilm collected from the kitchen, then the hospital. Statistically, the results reveal that there is a positive correlation (≥ .0001) with significance between the sources of biofilm. This work certainly makes the potential of household sink drain pipes for reservoir contagious pathogens more explicitly noticeable. Such knowledge would also be beneficial for prospective consideration of the threat to human public health and the environment.

Research – Modeling dependence of growth inhibition of Salmonella Typhimurium and Listeria monocytogenes by oregano or thyme essential oils on the chemical composition of minced pork

Wiley Online

The aim of this study was to compare the antimicrobial effect of selected essential oils (EOs) at concentration of 1% in minced pork from five different meat cuts (loin, ham, shoulder, neck, and belly) and to assess the influence of the chemical parameters of meat on EO efficiency, determined by the decrease of pathogens in comparison to a control in samples after storage at 3°C/7 d in a vacuum. The inhibition was significant ( < .05) only in minced pork from meat cuts with a fat content lower than 5% (leg, loin and shoulder). Salmonella enterica serovar Typhimurium was more sensitive than Listeria monocytogenes and oregano was more effective than thyme ( < .001). The inhibition of . Typhimurium depended mainly on the fat content (logarithmic dependence) and to a lesser degree on the pH, whereas pH was not found to be a significant predictor in the case of L. monocytogenes . The results of this study show that only lean minced meat (with a fat content max. 5%) is a suitable matrix for pathogen control by EOs.

Hong Kong – Hong Kong outbreak linked to sandwiches sickens 200 – Salmonella

Food Safety News

More than 220 people are part of an outbreak in Hong Kong linked to sandwiches.

The Centre for Health Protection (CHP) of the Department of Health reported 229 people were sick and 45 needed hospital treatment after eating the implicated sandwiches. It was previously reported that 27 people were sick and five needed hospital treatment.

The CHP has identified 96 clusters of suspected food poisoning. Among them, stool specimens from 12 sick people and one food sample tested positive for Salmonella. All those affected are now in stable condition.

The Centre for Food Safety (CFS) of the Food and Environmental Hygiene Department (FEHD), previously said that while following up on suspected food poisoning involving sandwiches, it was found they were produced by an unlicensed food factory in Hong Kong.

Research – Follow-up dairy study shows less Salmonella; wild boar meat rules reviewed

Food Safety News

A follow-up study on Salmonella prevalence among dairy cattle on a Swedish Island has found much lower levels.

In late 2019, the National Veterinary Institute (SVA) and Swedish Board of Agriculture (Jordbruksverket), did an anonymous national milk tank survey for antibodies against Salmonella.

Milk samples from all the dairy herds tested showed a generally low prevalence of Salmonella, except for Gotland and Öland. Gotland saw a change from 5.5 percent positive tank milk samples in 2013 to almost 22 percent in October 2019.

Meanwhile, the Swedish government has agreed to a request from the country’s food agency (Livsmedelsverket) for more time to look at food control across the country.

The assignment must be submitted no later than May 31 and a final report is due by Dec. 31, 2022.

Research – Essential Oils: Their Antibacterial Properties and Potential Applications in Foods–A Review

Pub Med

Abstract

In vitro studies have demonstrated antibacterial activity of essential oils (EOs) against Listeria monocytogenes, Salmonella typhimurium, Escherichia coli O157:H7, Shigella dysenteria, Bacillus cereus and Staphylococcus aureus at levels between 0.2 and 10 microl ml(-1). Gram-negative organisms are slightly less susceptible than gram-positive bacteria. A number of EO components has been identified as effective antibacterials, e.g. carvacrol, thymol, eugenol, perillaldehyde, cinnamaldehyde and cinnamic acid, having minimum inhibitory concentrations (MICs) of 0.05-5 microl ml(-1) in vitro. A higher concentration is needed to achieve the same effect in foods. Studies with fresh meat, meat products, fish, milk, dairy products, vegetables, fruit and cooked rice have shown that the concentration needed to achieve a significant antibacterial effect is around 0.5-20 microl g(-1) in foods and about 0.1-10 microl ml(-1) in solutions for washing fruit and vegetables. EOs comprise a large number of components and it is likely that their mode of action involves several targets in the bacterial cell. The hydrophobicity of EOs enables them to partition in the lipids of the cell membrane and mitochondria, rendering them permeable and leading to leakage of cell contents. Physical conditions that improve the action of EOs are low pH, low temperature and low oxygen levels. Synergism has been observed between carvacrol and its precursor p-cymene and between cinnamaldehyde and eugenol. Synergy between EO components and mild preservation methods has also been observed. Some EO components are legally registered flavourings in the EU and the USA. Undesirable organoleptic effects can be limited by careful selection of EOs according to the type of food.
