Research – Norovirus v Dishwashers

Food Poisoning Bulletin

What do norovirus and baked-on lasagna have in common? Both can survive the dishwasher.

Researchers at Ohio State University have made a discovery that may help to explain why restaurants have a hard time controlling the spread of norovirus, the leading cause of food poisoning worldwide. About half of all foodborne illness outbreaks in the US are caused by norovirus, most of them, about 80 percent, happen between November and April, according to the Centers for Disease Control and Prevention (CDC).

Research – E.coli O157 Testing in Water

Science Direct

The performances of three chromogenic agars were evaluated for the recovery of Escherichia coli O157:H7 from spiked de-chlorinated tap, ground and surface water, and treated drinking water samples. The chromogenic agars: ChromAgar O157 (CHROM), Rainbow Agar O157 (RB) and HiCrome EC O157 (HC) were compared to cefixime-tellurite Sorbitol MacConkey (CT-SMAC), commonly used for the isolation of E. coli O157:H7. Confirmation of suspect E. coli O157:H7 colonies were performed by colony real-time PCR (C-RTi-PCR) based on the presence of Shiga-toxin genes (stx1 and stx2). Recovery of inoculated E. coli O157:H7 from de-chlorinated tap water indicated that RB and CHROM agars demonstrated improved recovery when compared to HC or CT-SMAC. There was a significant drop in recovery on all agars tested after 120 hours (day 5). Twenty de-chlorinated tap and/or treated drinking water samples were inoculated with a pure culture of E. coli O157:H7 (ATCC 43894), and a mixed culture of E. coli O157:H7 (ATCC 43894), E. coli strain K-12, and Enterococcus faecalis (ATCC 063589). After a 48 hour holding time, the recovery using CHROM (99 %) and HC (12 %) from samples contaminated with the pure culture were found to be significantly different (p < 0.05). Recovery results using CHROM (39 %) and CT-SMAC (32 %) from samples contaminated with the mixed culture after 48 hour holding time were not significantly different (p > 0.05). Analysis by C-RTi-PCR of forty five environmental water samples (surface, sewage, and final effluents) which were negative for E. coli O157:H7 showed an incidence of false suspect positive colonies of 38 % (CHROM), 53 % (RB), 58 % (HC), and 91 % (CT-SMAC). Further analysis of eight of the environmental samples inoculated with E. coli (ATCC 43894) showed 100% recovery when utilizing CHROM, 50% when using RB and 40 % when using HC. In addition, the C-RTi-PCR positive confirmation rate was 100% for CHROM and HC and 65% for RB. CHROM demonstrated improved recovery of E. coli O157:H7 over RB, HC, and CT-SMAC in terms of sensitivity and specificity.

USA – Small Turtles On-Going Salmonella Risk

Food Poisoning Bulletin 800px-Florida_Box_Turtle_Digon3_re-edited

Six ongoing Salmonella outbreaks that have sickened a total of 248 people in 34 states have been linked to illegal pet turtles, according to the Centers for Disease Control and Prevention (CDC).  Almost 70 percent of those who became ill were children under the age of 10.

It is precisely because of Salmonella risk , especially to young children, that the Food and Drug Administration banned the sale and distribution of small  turtles as pets in 1975. Turtles with shells shorter four inches should not be purchased as pets or given as gifts.

Research – New study sheds light on how Salmonella spreads in the body

Eureka Alert

Findings of Cambridge scientists, published today in the journal PLoS Pathogens, show a new mechanism used by bacteria to spread in the body with the potential to identify targets to prevent the dissemination of the infection process.

Salmonella enterica is a major threat to public health, causing systemic diseases (typhoid and paratyphoid fever), gastroenteritis and non-typhoidal septicaemia (NTS) in humans and in many animal species worldwide. In the natural infection, salmonellae are typically acquired from the environment by oral ingestion of contaminated water or food or by contact with a carrier.  Current vaccines and treatments for S. enterica infections are not sufficiently effective, and there is a need to develop new therapeutic strategies.

Dr Andrew Grant, lead author of the study from the University of Cambridge, said: “A key unanswered question in infectious diseases is how pathogens such as Salmonella grow at the single-cell level and spread in the body.  This gap in our knowledge is hampering our ability to target therapy and vaccines with accuracy.”

Canada – Recall Mould Mycotoxin Patulin

VISTA BELLA MICHEL JODOIN SPARKLING APPLE MUST NO ALCOHOL 750 mL LOT 1112 6 09780 01127 7 Chemical – Toxin – Patulin

If you require additional information about an individual recall, please contact us.

Patulin is a mycotoxin produced by a variety of molds, in particular, Aspergillus and Penicillium. It is commonly found in rotting apples, and the amount of patulin in apple products is generally viewed as a measure of the quality of the apples used in production. It is not a particularly potent toxin, but a number of studies have shown that it is genotoxic, which has led to some theories that claim that it may be a carcinogen, though animal studies have remained inconclusive.Patulin is also an antibiotic.Several countries have instituted patulin restrictions in apple products. The World Health Organization recommends a maximum concentration of 50 µg/L in apple juice.

In European Union, the limit is set to 50 micrograms per kilogram (µg/kg) in both apple juice and cider, and to half of that concentration, 25 µg/kg in solid apple products and 10 µg/kg in products for infants and young children. These limits came into force on 1 November 2003.

Canada Research Advice – Preventing Botulism in Infants

Health Canada

Health Canada is advising parents and caregivers not to feed honey to infants less than one year of age. Honey is the only food in Canada to which infant botulism has been linked. Healthy children over one year of age can safely eat honey because they have a very low risk of developing infant botulism.

Infant botulism is caused by bacteria called Clostridium botulinum, which commonly exist in nature. Although the bacteria are unable to grow and produce toxins in honey, they may grow and produce toxins in the baby’s body should an infant consume honey and could cause paralysis.

Since the first reported case in 1979, there have been 42 reported cases of infant botulism in Canada. Parents and caregivers can prevent infant botulism by never feeding honey to infants less than one year of age. This includes never adding honey to baby food and never using honey on a soother.

Most honey produced in Canada is not contaminated with the bacteria that cause infant botulism, however you are better off playing it safe.

The bacteria that cause botulism are microscopic and do not change the colour, odour or taste of food. The bacteria are not destroyed by cooking or pasteurization.
