USA – DG/health Naturals Baby Cough Syrup Recalled For Contamination

Food Poisoning Bulletin 

Kingston Pharma, LLC of Massena, New York is recalling one lot of DG/health Naturals Baby Cough Syrup + Mucus because it may be contaminated with Bacillus cereus/Bacillus circulans. Bacillus cereus in food products can cause two syndromes: one of vomiting, and the other of diarrhea.

Research – Assessing the microbiological safety status of most commonly consumed food items sold at local and branded restaurants of Faisalabad, Pakistan

Wiley Online Library

Abstract

The current study was designed to assess the microbial safety status of rice and chicken dishes offered for sale at various local and branded restaurants. Purposely, 24 samples of rice and chicken dishes were collected from eight local and branded restaurants of Faisalabad city. All the collected samples were subjected to microbiological examination to determine the prevalence and comparative enumeration of Bacillus cereus, Escherichia coli (rice), Salmonella and Campylobacter (chicken). Results pertaining to the enumeration of B. cereus and E. coli exhibited highest count of 2.12 × 108 and 2.59 × 107 cfu/g, respectively. Both strains were found to be higher among the samples collected from branded restaurants. Likewise for chicken dishes, the highest count observed for Salmonella and Campylobacter were 2.50 × 107 and 1.87 × 108 cfu/g, respectively. Further, the results of current study revealed that 38% of rice samples collected from local restaurants and 63% from branded restaurants have unsatisfactory safety status for B. cereus. Similarly, for E. coli, 63 and 42% samples were found unsatisfactory from local and branded restaurants, respectively. On the other hand, the percentage of chicken samples with unacceptable safety status according to Salmonella and Campylobacter standards were 46 & 58% and 54 & 46% for local and branded restaurants, respectively.

Practical applications

Safe handling of food during preparation and adherence to the food safety principles are key factors in determining the safety of food served at any restaurant. The study focused on previously unreported microbial safety status of some commonly sold food items at local and branded restaurants. The results and suggestions of this study will help the food handlers and regulatory bodies to map out the potential gaps in food supply chain to reduce the incidence of microbial contamination in cooked food items. The study will provide guidance for the restaurant industry to improve the overall safety of cooked foods by taking the corrective measures in the light of results presented in this article.

Research – What’s happening inside your body when you have food poisoning? A new study into Bacillus cereus has some clues

ABC Net

bacillus

You know the symptoms well enough. The clammy chill that washes over your body, the clenching in your stomach and then, finally, the dash to the bathroom, possibly accompanied by a split-second decision about which part of your body to aim at the toilet first.

But what’s happening inside your body when you have food poisoning?

Research published today has given us a slightly clearer idea, at least for one type of bacteria.

A team from the Australian National University looked at the way the body responds to the bacteria Bacillus cereus, which can cause food poisoning and sometimes lead to serious infections elsewhere in the body, including sepsis, pneumonia and meningitis.

They found a toxin secreted by the bacteria binds directly to cells in the human body and punches holes in the cells to kill them, triggering an immune response.

Research -Enterotoxigenic structures of Bacillus cereus strains isolated from ice creams

Wiley Online Library

Abstract

This study was conducted to investigate the presence of Bacillus cereus in ice cream samples and to identify associated toxin genes by mPCR. 125 ice cream samples were used as material. A total of 38 samples were found to be positive for B. cereus. It was found that 31.9% of the isolates had three enterotoxic HBL complex encoding genes, 10.6% had two hbl genes and 6.3% contained one hbl gene. On the other hand, 15.9% of the isolates contained three NHE complex encoding genes, 31.9% had two nhe genes and 20.2% contained one nhe gene. Also 7.4% of isolates were found to contain both NHE and HBL complexes while ctyK1 was not detected from any isolate. The presence of B. cereus and their enterotoxigenic genes in ice creams may be a potential risk for public health.

Practical applications

The presence of the B.cereus in high numbers and the toxins in foods pose a potential risk in terms of health and food spoilage. In food poisoning cases, hbl, nhe, cytK, and the effect of emetic toxin are especially notable. The resistance of spores against pasteurization and psychrotolerant feature enable the explanation of the existence of B. cereus in ice‐cream.
