Research – Prevalence and Characterisation of Clostridium perfringens Isolates in Food-Producing Animals in Romania
The aim of the current study was to investigate the prevalence of Clostridium perfringens (C. perfringens) recovered from animal faeces, as well as to determine the antimicrobial susceptibility of such isolates. A total of 14 (14/100; 14%) C. perfringens isolates were isolated from the 100 analysed samples (twelve recovered from faecal samples collected from pigs and two from veal calves’ faecal samples). The preponderant genotype was type A, with all isolates being cpa-positive. The most potent antimicrobial agents against C. perfringens proved to be vancomycin, rifampicin and lincomycin. A strong resistance to tetracycline (71.4%), penicillin (64.2%), erythromycin (42.8%) and enrofloxacin (35.7%) was also observed. To the best of our knowledge, this is the first analysis regarding the prevalence, characterization and antimicrobial susceptibility of C. perfringens in food-producing animals in Romania, adding further evidence for the probable role of animals as a source of resistant C. perfringens strains.

Viet Nam – HCMC botulism patient dies before receiving antitoxin sent from Switzerland
The World Health Organization has dispatched rare drug to HCMC to treat patients critically ill with botulism after eating pork bologna and fermented food, but one died shortly after it arrived.
Sent from Switzerland, six vials of botulism antitoxin heptavalent (BAT) arrived on Wednesday to be administered to the three men, aged 18, 26 and 45, the Ministry of Health said.
Two of them are under treatment at Cho Ray Hospital and the other at Gia Dinh Hospital.
But the 45-year-old patient at Gia Dinh died on Wednesday night before he was injected with the drug, the hospital announced Thursday morning.
Produced by Emergent BioSolutions Canada Inc., the drug effectively neutralizes all known botulinum nerve toxin serotypes. Without it, botulism patients could be paralyzed permanently.
Between May 13 and 20 six people in Thu Duc City suffered from botulinum poisoning, five after eating pork bologna sold by street vendors and one due to eating a type of fermented food.

Quebec – Notice not to consume smoked mussels and warning concerning the lack of information necessary for the consumption of certain smoked fish products, prepared and sold by Poissonnerie de la Baie inc. by Bonaventure – Clostridium botulinum
The Ministry of Agriculture, Fisheries and Food (MAPAQ), in collaboration with the company Poissonnerie de la Baie inc., located at 170, avenue de Port- Royal , in Bonaventure, warns the public not to consume the product indicated in the table below, because the retailer mentioned above has not prepared and packaged it in such a way as to ensure its safety. Indeed, this product could promote the proliferation of the bacterium Clostridium botulinum .

The products that are the subject of this warning were offered for sale until May 12, 2023 inclusively, and only at the establishment designated above. The smoked fish products were vacuum packed in a transparent plastic bag and the smoked mussels were packed in glass jars with a metal lid. The products were all sold chilled. The label of the products included, in addition to their name, the words “Poissonnerie de la Baie”.
The operator is voluntarily recalling the products in question. It has agreed with MAPAQ to issue this warning as a precautionary measure.
Smoked mussels : people who have this product in their possession are advised not to consume it. They must return it to the establishment where they bought it or throw it away. Even if the affected product shows no signs of tampering or suspicious odors, its consumption may represent a health risk.
Maple Smoked Salmon Bites and Smoked Turbot Fillets : People who have either of these products in their possession are advised not to consume it if it has been packaged for more than 14 days. They must return it to the establishment where they bought it or throw it away. Even if the affected products show no signs of tampering or suspicious odors, their consumption may represent a health risk. In fact, when smoked fish is sold refrigerated, mandatory preventive measures must be taken with regard to the type of packaging and the shelf life.
It should be noted that no case of illness associated with the consumption of these foods has been reported to MAPAQ to date.

Research – FSA Vacuum Packing/MAP Guidance – more questions asked
In June 2022 CFA Director General Karin Goodburn MBE gave evidence to the Advisory Committee on the Microbiological Safety of Food (ACMSF) Subgroup conducting the review of the entire risk basis of the FSA Guidelines on the control of non-proteolytic Clostridium botulinum in the vacuum and modified atmosphere packaging of chilled food (CFA News 58) and looking more widely at botulism risks.
The subgroup was not authorised by FSA to review the guidance in relation to fresh meat although industry maintains that it does not reflect internationally-established risk. CFA is seeking correction of technical errors and removal of UK-only technical barriers to businesses. Instead, as is standard for other pathogens, information required for the use of HACCP should be provided by FSA including continuing to allow the use of risk-based data for the use of novel thermal and other processes.

Research – Physical Treatments to Control Clostridium botulinum Hazards in Food
Abstract
Clostridium botulinum produces Botulinum neurotoxins (BoNTs), causing a rare but potentially deadly type of food poisoning called foodborne botulism. This review aims to provide information on the bacterium, spores, toxins, and botulisms, and describe the use of physical treatments (e.g., heating, pressure, irradiation, and other emerging technologies) to control this biological hazard in food. As the spores of this bacterium can resist various harsh environmental conditions, such as high temperatures, the thermal inactivation of 12-log of C. botulinum type A spores remains the standard for the commercial sterilization of food products. However, recent advancements in non-thermal physical treatments present an alternative to thermal sterilization with some limitations. Low- (<2 kGy) and medium (3–5 kGy)-dose ionizing irradiations are effective for a log reduction of vegetative cells and spores, respectively; however, very high doses (>10 kGy) are required to inactivate BoNTs. High-pressure processing (HPP), even at 1.5 GPa, does not inactivate the spores and requires heat combination to achieve its goal. Other emerging technologies have also shown some promise against vegetative cells and spores; however, their application to C. botulinum is very limited. Various factors related to bacteria (e.g., vegetative stage, growth conditions, injury status, type of bacteria, etc.) food matrix (e.g., compositions, state, pH, temperature, aw, etc.), and the method (e.g., power, energy, frequency, distance from the source to target, etc.) influence the efficacy of these treatments against C. botulinum. Moreover, the mode of action of different physical technologies is different, which provides an opportunity to combine different physical treatment methods in order to achieve additive and/or synergistic effects. This review is intended to guide the decision-makers, researchers, and educators in using physical treatments to control C. botulinum hazards.
