Research – Case Report: Identification of the Source for Salmonella Contamination of Carcasses in a Large Pig Slaughterhouse

MDPI

To identify the major source of Salmonella contamination in a pig slaughterhouse, samples were collected from the clean and unclean area and Salmonella isolates were further typed. Carcasses entering the clean area showed a Salmonella contamination rate of 96.7% in the oral cavity and 55.0% in the rectum content samples. Evisceration seemed not to be critical as the contamination rate of the carcasses was similar before (16.7%) and after (18.3%) this slaughter step. In the unclean area, a limited number of oral cavity samples were positive after bleeding, while a dramatic increase of positives was observed after dehairing. Salmonella was detected in up to 0.01 mL of the recycled water collected from the dehairing machine. Genotyping of Salmonella isolates showed that similar pulsotypes were present in the oral cavity and recycled water. Based on these observations it can be concluded that the recycled water used in the dehairing machine was the major source for the carcass contamination in this slaughterhouse. View Full-Text

Research – High risk of potential diarrheagenic Bacillus cereus in diverse food products in Egypt

Journal of Food Protection

bacillus

Bacillus cereus is one of the important foodborne pathogens that can be found in various foodstuffs; causing diarrheal and/or emetic syndromes. This study aimed to evaluate the prevalence, antimicrobial susceptibility profile, pathogenic potential, and genotypic diversity of B. cereus isolated from diverse food products from markets in Cairo, Egypt. A total of 39 out of 165 food samples were positive for B. cereus (detection rate of 24%) with a contamination level ranged from 2 to 6 log CFU/g and a higher incidence of > 3 log bacterial count. Antimicrobial susceptibility testing showed that B. cereus isolates were fully sensitive to all tested antimicrobial agents except β-lactams. The pathogenic potential of the 39 B. cereus isolates was assessed by detecting and profiling the secreted virulence or toxin encoding genes including the chromosomal-carried genes hblA , bceT , plc , sph , nheA , entFM , cytK associated with the diarrheal syndrome and the plasmid-carried ces gene associated with the emetic syndrome. The most frequently detected  genes were hblA , nheA and entFM . All isolates harbored more than one of the diarrheal enterotoxins encoding genes with the genetic profile hblA-bceT-nheA-entFM-cytK-plc-sph was the most prevalent (in 20/39 isolates). The emetic toxin ces was not detected at all. ERIC-based analysis of the 20 B. cereus isolates harboring the prevalent genetic profile revelated that they were genetically distinct. In conclusion, the findings of this study provide useful information for public health management and serve as a warning of the potential risk of diarrheagenic B. cereus in diverse food products. Therefore, the consideration to extensively study the epidemiology of this food pathogen in Egypt is warranted. Additionally, strict procedures should be applied to monitor, protect, and safely handle food products, particularly ready to eat foodstuffs that are usually consumed without heat treatment.

Hong Kong – Centre for Food Safety announces test results on Lunar New Year food (first phase)

CFS

The Centre for Food Safety (CFS) of the Food and Environmental Hygiene Department today (January 15) announced the test results of a recently completed seasonal food surveillance project on Lunar New Year (LNY) food (first phase). The test results of around 570 samples collected were satisfactory, except for a date sample found to contain a preservative at a level exceeding the legal limit and in breach of the food labelling regulation and a rice cake sample found with sodium content inconsistent with the declared content on its nutrition label, which were announced earlier.

A spokesman for the CFS said, “The LNY is coming soon and the CFS is conducting this seasonal food surveillance project in two phases. During the first phase of the project, different types of LNY food including steamed puddings (e.g. turnip puddings and festive cakes), fried dumplings (e.g. sesame balls and crispy triangles), candies, glutinous rice balls, melon seeds and dried aquatic products were collected from different retailers (including online retailers) for chemical and microbiological tests as well as nutrition content analysis.”

Chemical tests targeted preservatives, colouring matters, metallic contaminants and others. Microbiological tests covered different food poisoning pathogens. For nutrition content analysis, the contents of total fat, sodium and sugars of the samples were tested to see if the test results were consistent with the declared values on the nutrition labels.

The spokesman urged the food trade to observe the relevant laws and regulations in the preparation of food, follow Good Manufacturing Practice and use permitted food additives only in an appropriate manner. Retailers should source food from reliable suppliers, and conduct quality checks of incoming materials and end products to ensure that ingredients used are within legal standards. In addition, the food trade should maintain proper records in accordance with the requirements of the Food Safety Ordinance to allow source tracing if needed.

The spokesman also advised consumers to buy LNY food from reliable retailers with good hygiene conditions; make sure the packaging of prepackaged cakes and snacks is intact and the products have not expired; refer to the nutrition labels on the sugar, salt (sodium) and fat content and more for healthy choices; and pay attention to the hygiene conditions of food containers and the personal hygiene of staff when buying loose-packed food (e.g. candied lotus seeds, nuts and melon seeds).

“Consumers should choose food products with natural colours. Bright white pistachios may have been bleached and melon seeds with an unnatural gloss may have had mineral oil added. Consumption of these food products can cause gastrointestinal discomfort,” the spokesman said.

“Festive cakes that are not for immediate consumption should be kept refrigerated or stored according to the instructions on the package, and should be eaten before they expire. Reheat hot-served festive cakes thoroughly before consumption, consume them as soon as possible, and avoid keeping them at room temperature for a long time. Foods like nuts and melon seeds should not be kept for a long time. Those with mould or an abnormal smell or taste should not be eaten,” he added.

The spokesman reminded the public to maintain a balanced diet and avoid foods that are high in energy, sugar, salt or fat during the LNY.

The CFS will continue to conduct surveillance on LNY food and the second-phase results will be released in a timely manner to ensure food safety.
