MARINE DRUGS 22/01/20 Effects of Chitosan on Clostridium perfringens and Application in the Preservation of Pork Sausage. 2.2. Effect of Chitosan on Decimal Reduction Time of C. perfringens Spores The outbreak of C. perfringens poisoning is generally initiated by C. perfringens spores that survive the cooking process and are germinated in food, eventually producing enterotoxins in the intestinal tract after ingestion . Therefore, reduction of heat resistance of the spores to decrease spore survival during heating is a preventative approach for C. perfringens poisoning .
The effect of DD95 at 250 ppm on the decimal reduction time (D value) of tested C. perfringens strains during heating are shown in Table 1. The D values at 80 °C (D80) for spores of C. perfringens CCRC 10,648 and CCRC 13,019 were 41.15 and 40.98 min, respectively. In the presence of 250 ppm DD95, D80 values decreased to 39.52 and 39.21 min, respectively. Table 1. 2.3. Figure 2. Figure 3.

UNIBE_CH 04/06/20 Deadly bacterial infection in pigs deciphered (Clostridium perfringens) - New-born piglets often die painfully from infection with an intestinal bacterium. A team of researchers from 3 faculties at the University of Bern has now discover. The Clostridium perfringens bacterium is part of the large Clostridium genus which can cause various fatal illnesses in animals and humans. Clostridium infections are widespread. These bacteria are dangerous because they produce extremely strong poisons (toxins) which cause targeted damage to the host’s cells. Dreaded diseases caused by Clostridium include botulism, tetanus, gas gangrene and intestinal infections, for example.
Horst Posthaus’s group in the Institute of Animal Pathology at the University of Bern is researching an intestinal infection in pigs which is caused by Clostridium perfringens. 10 years ago, they were already able to demonstrate that the toxin produced by the bacteria, the so-called beta toxin, kills vascular cells and thus causes bleeding in the piglet’s intestine. Until now, however, it was unclear why the toxin attacked specifically these cells and not others. A key molecule Researchers at the University of Bern join forces Better prophylaxis and medications.
TOXINS 23/03/19 Targeted Mass Spectrometry Analysis of Clostridium perfringens Toxins. EN_WIKIPEDIA - Clostridium perfringens. Clostridium perfringens (formerly known as C. welchii, or Bacillus welchii) is a Gram-positive, rod-shaped, anaerobic, spore-forming pathogenic bacterium of the genus Clostridium. C. perfringens is ever-present in nature and can be found as a normal component of decaying vegetation, marine sediment, the intestinal tract of humans and other vertebrates, insects, and soil.
It has the shortest reported generation time of any organism at 6.3 minutes in thioglycolate medium. C. perfringens is one of the most common causes of food poisoning in the United States, alongside norovirus, Salmonella, Campylobacter, and Staphylococcus aureus. However, it can sometimes be ingested and cause no harm.  The action of C. perfringens on dead bodies is known to mortuary workers as tissue gas. It causes extremely accelerated decomposition, and cannot be stopped by normal embalming measures.
These bacteria are resistant to the presence of formaldehyde in normal concentrations. INTECH 14/03/12 Bacteriophages of Clostridium perfringens.

The former owner of a North Somerset pub has been fined £14,000 after nearly 200 people fell ill after eating at his venue on Mother's Day. Hundreds of people ate a meal at The Old Farmhouse in Nailsea on March 11, 2018, but 186 fell ill with food poisoning after their visit. The victims, who had eaten over four sittings, were aged from babies to diners in their 80s and developed symptoms of diarrhoea, stomach cramps and sickness. Bristol Live reports that upon hearing about the scores of ill diners, North Somerset Council environmental health department launched an investigation, tracing the 398 people who had eaten at The Old Farmhouse that day. Public Health England (PHE) was also informed. Environmental health officers took samples of lamb, beef, gravy and from some of the equipment used at the pub during their visit.
Officers returned to the pub the next day where they met Eric Montgomery, the sole director of the company M and M Hospitality which ran The Old Farmhouse at the time.

Highlights Clostridium perfringens has been shown to form mono-species biofilms. C. perfringens mono-species biofilms were able to protect the bacterial cells from the action of commonly used disinfectants. Sodium hypochlorite solution was shown to be effective on C. perfringens biofilms. Mono-species biofilms were more tolerant to disinfectants than the mixed biofilms.

IOWA STATE UNIVERSITY - 2015 - Thèse en ligne : Efficacy of decreased nitrite concentrations on Clostridium perfringens outgrowth during an Appendix B cooling cycle for ready-to-eat meats. Abstract Increased popularity of natural and organic processed meats can be attributed to the growing consumer demand of preservative-free foods. In order to meet consumer demand, processors have begun using celery juice concentrate in place of sodium nitrite creating no-nitrate-no-nitrite added meat products while maintaining the characteristics unique to conventionally cured processed meats.
Natural cures typically have lower ingoing nitrite concentrations which could allow for increased pathogen growth, such as Clostridium perfringens, during cooling as required by USDA, FSIS Appendix B. The objective of this study was to investigate the implications associated with reduced nitrite concentrations and their ability to inhibit C. perfringens outgrowth during a 15 hour cooling cycle.

Highlights Method for assessing the Clostridium perfringens growth during cooling operations. Probabilistic calculations combining thermal equations and microbiological models. Thermal equations parameters assessed by tests carried out in a kitchen. Possibility of using this method to validate cooling operations in catering. Abstract The cook-chill operation, a widely used process within central cooking facilities, implies that cooked dishes have to be quickly cooled down immediately after cooking in order to prevent any food-borne diseases due to Clostridium perfringens. This document presents an experimental method to validate the sanitary efficiency of the cooling process.
The tests consisted in monitoring food temperature at the center of the containers from the end of cooking until the beginning of cold room storage. From the monitored time–temperature profiles, thermal cooling equations were established for modeling. Keywords Copyright © 2013 Elsevier Ltd. MICROBIOLOGY AUSTRALIA - MAI 2013 - Food Safety.

(John Bates – Food Poisoning lectures). Clostridium perfringens, a Gram-positive anaerobic spore-forming bacillus, has been responsible for a large number of food poisoning events in Australia. Classical Type A Clostridium perfringens are typically β-haemolytic on Horse Blood Agar (HBA) and the spores are oval and subterminal with no swelling of the sporangium. The main criteria for diagnosis of food poisoning caused by Cl. perfringens include the detection of at least 1 × 105 vegetative cfu/g in incriminated food, and/or a faecal spore count of at least 1 × 106 cfu/g in faeces from ill complainants.

Abstract The contamination of enterotoxigenic Clostridium perfringens spores on food contact surfaces posses a serious concern to food industry due to their high resistance to various preservation methods typically applied to control foodborne pathogens.
In this study, we aimed to develop an strategy to inactivate C. perfringens spores on stainless steel (SS) surfaces by inducing spore germination and killing of germinated spores with commonly used disinfectants. The mixture of l-Asparagine and KCl (AK) induced maximum spore germination for all tested C. perfringens food poisoning (FP) and non-foodborne (NFB) isolates. Incubation temperature had a major impact on C. perfringens spore germination, with 40 °C induced higher germination than room temperature (RT) (20 ± 2 °C). In spore suspension, the implementation of AK-induced germination step prior to treatment with disinfectants significantly (p < 0.05) enhanced the inactivation of spores of FP strain SM101.
