Blame the consumer or chef, Scottish-style; campylobacter found in 80% of chicken liver packs; just cook it

Following a spate of campylobacter outbreaks linked to chicken liver paté in the U.K., researchers at Aberdeen University found the bug in more than 80 per cent of packs of chicken liver paté bought from supermarkets and butchers during a two-year survey.

The Scotsman.com cites Dr Norval Strachan, the researcher in food safety and epidemiology who led the study, as saying the bug had been found in 81 per cent of raw chicken livers purchased from a typical range of supermarkets and butchers over a two-year period. “… last year 14 outbreaks of the bug in the UK were associated with consumers eating chicken or duck liver paté. By cooking the livers properly and ensuring good hygiene in the kitchen these episodes can be avoided. However, some celebrity chefs and many recipes advocate only partially cooking chicken liver to ensure that it is pink in the middle.”

Dr Jacqui McElhiney, policy adviser at the Food Standards Agency in Scotland, underlined the need for proper precautions to be taken to prevent the risk of food poisoning.

“Unfortunately, levels of campylobacter in raw chicken are high, so it’s really important that chefs thoroughly cook chicken livers fully to kill any bacteria, until there is no pinkness left in the centre, even if recipes call for them to be seared and left pink in the middle. “It’s the only way of ensuring the paté will be safe to serve.”

This is all sorta confusing: researchers found 80 per cent of raw chicken liver contaminated with campylobacter, but said they were looking at packs of chicken liver pate at supermarkets. But the food safety folks blame celebrity chefs? Do they make pre-packaged pate? Are consumers supposed to cook paté they buy pre-packaged at the supermarket? Guess they were talking about raw liver. So then what about the risk of cross-contamination. Maybe something is lost in translation; I speak Scottish as fluently as Australian.

And pinkness is a lousy indicator of whether any meat has been cooked to reduce dangerous bacteria such as campylobacter. So is piping hot.

Pathogenic potential to humans of bovine Escherichia coli O26, Scotland

Chase-Topping et al. report in the current issue of Emerging Infectious Disease that Escherichia coli O26 and O157 have similar overall prevalences in cattle in Scotland, but in humans, Shiga toxin–producing E. coli O26 infections are fewer and clinically less severe than E. coli O157 infections.

To investigate this discrepancy, we genotyped E. coli O26 isolates from cattle and humans in Scotland and continental Europe. The genetic background of some strains from Scotland was closely related to that of strains causing severe infections in Europe. Nonmetric multidimensional scaling found an association between hemolytic uremic syndrome (HUS) and multilocus sequence type 21 strains and confirmed the role of stx2 in severe human disease. Although the prevalences of E. coli O26 and O157 on cattle farms in Scotland are equivalent, prevalence of more virulent strains is low, reducing human infection risk.

However, new data on E. coli O26–associated HUS in humans highlight the need for surveillance of non-O157 enterohemorrhagic E. coli and for understanding stx2 phage acquisition.

Dangerous E. coli infections up 19% in Scotland; declines in salmonella, campylobacter

Health Protection Scotland (HPS) said it had recorded 253 positive cases of E. coli during 2011, up from 212 the previous year.

The agency blamed the increase on a UK-wide outbreak believed to have originated from contaminated vegetables. The outbreak, between December 2010 and July 2011, saw 250 cases of E. coli infection throughout England, Wales and Scotland and 74 victims treated in hospital.

A subsequent investigation pointed to a possible link between leeks and potatoes bought loose and prepared in the home.

However, the HPS report also noted that the apparent spike in E. coli between 2010 and 2011 was partly due to the unusually low rate of E. coli infection in 2010.

The report also noted decreases in salmonella and campylobacter.
In 2011, HPS received reports of 736 cases of salmonella infection – a decrease of almost 22% on the 941 reported in 2010.

Cases of campylobacter were also down 3.6% to 6366 last year, although the figure remains "one of the highest on record."

Follow the bug: 10% of chicken packaging contaminated with campylobacter – on the outside

Just cook it doesn’t cut it.

Especially when 10 per cent of 42 samples of packaging on chicken is contaminated with campylobacter on the outside.

(And another reason to wrap any poultry in extra plastic, especially if placing into a reusable bag.)

The Royal Environmental Health Institute of Scotland and other groups said the study confirmed the results of a previous survey by the group that also showed that approximately 10% of samples were contaminated.

The Chairman of the West of Scotland Food Liaison Group (WOSFLG), Mr Leslie Paton said, “We know that it is fairly common to find Campylobacter in raw chicken but we were quite concerned about the extent to which the external surfaces of the packaging were also contaminated. There are implications for anyone handling such packaging and consumers should take care as there is a possibility of cross contamination to other surfaces and foods.”

2 sick in Scotland; recall of Loyd Grossman Korma sauces following botulism link

Preliminary tests carried out by the U.K. Health Protection Agency (HPA) have identified the toxin that causes botulism from a used jar of Loyd Grossman Korma sauce. The Food Standards Agency (FSA) is advising consumers who have purchased the particular batch of the product to dispose of it and not consume. A full recall of this product batch has been issued and the sauce is being removed from shop shelves.

This follows two cases of botulism in one family in Scotland where the contaminated jar of sauce was discovered. No further cases have been identified to date. There is no evidence to suggest that the samples taken from the jar for testing could have been separately contaminated from another source. Further tests on this and from another unused jar of the korma sauce taken from the home of the patients are underway.

The affected batch is: 350g jars of Loyd Grossman Korma sauce with a best before date of February 2013. The sauce has a batch code of: 1218R 07:21

Health professionals across the UK have been made aware of the suspected cases and advised to look out for people of all ages with possible symptoms.

E. coli O157 cases double in Scotland, new strain emerges

There have been 55 cases of E.coli O157 in Scotland in the first three months of 2011, compared to 14 last year and double the decade average of 25.

Health Protection Scotland (HPS) said more than half of the cases reported at the start of 2011 were found to be a new strain of the infection, phage type 8 (PT8), which has previously been reported in other parts of the U.K.
 

11% of E. coli O157 in Scotland via secondary spread

In November 1996, over 400 fell ill and 21 were killed in Scotland by E. coli O157:H7 found in deli meats produced by family butchers John Barr & Son. The Butcher of Scotland, who had been in business for 28 years and was previously awarded the title of Scottish Butcher of the Year, was using the same knives to handle raw and cooked meat.

Locking et al report in Emerging Infectious Disease that to determine the proportion of Escherichia coli O157 cases in Scotland attributable to secondary spread, we analyzed data obtained through entire-population enhanced surveillance. We identified 11% of cases as secondary. Secondary cases in single households were younger than secondary cases in outbreaks affecting >1 household and had similar risk for hemolytic uremic syndrome.

UK guidance to prevent E. coli contamination: too little, too late***

In November 1996, over 400 fell ill and 21 were killed in Scotland by E. coli O157:H7 found in deli meats produced by family butchers John Barr & Son. The Butcher of Scotland, who had been in business for 28 years and was previously awarded the title of Scottish Butcher of the Year, was using the same knives to handle raw and cooked meat.

In a 1997 inquiry, Prof. Hugh Pennington recommended, among other things, the physical separation, within premises and butcher shops, of raw and cooked meat products using separate counters, equipment and staff.

Five-year-old Mason Jones (right) died a painful and unnecessary death on Oct. 4, 2005, from E. coli O157 as part of an outbreak which sickened 157 — primarily schoolchildren — in south Wales.?

In a 2009 inquiry, Prof. Pennington concluded that serious failings at every step in the food chain allowed butcher William Tudor to start the 2005 E. coli O157 outbreak, and that while the responsibility for the outbreak, “falls squarely on the shoulders of Tudor,” there was no shortage of errors, including:??

• local health types did not sufficiently assess or monitor John Tudor & Son’s food safety management or HACCP plan;??
• the abattoir was allowed to continue slaughtering despite longstanding and repetitive failures, in breach of legislative requirements and without significant improvements; and,?
• the procurement process was “seriously flawed in relation to food safety.”??

Pennington also heard that butcher Tudor:

• encouraged staff suffering from stomach bugs and diarrhea to continue working;
• knew of cross-contamination between raw and cooked meats, but did nothing to prevent it;
• used the same packing in which raw meat had been delivered to subsequently store cooked product;
• operated a processing facility that contained a filthy meat slicer, cluttered and dirty chopping areas, and meat more than two years out of date piled in a freezer;
• a cleaning schedule at the factory that one expert called "a joke;"
• falsified crucial health and safety documents and lied about receiving hygiene awards; and,
• supplied schools with meat that was green, smelly and undercooked.

Prof Pennington said he was disappointed that the recommendations he made more than 10 years ago, following the E. coli O157 outbreak in Wishaw, Scotland, which killed 21 people had failed to prevent the South Wales Valleys outbreak.

Today, the U.K. Food Standards Authority issued guidance to clarify the steps that food businesses need to take to control the risk of contamination from the food bug E. coli O157.

Serious outbreaks of E. coli in Scotland in 1996 and Wales in 2005 resulted in serious illness in some individuals and, in a few cases, death. These outbreaks were attributed to cross-contamination arising from the poor handling of food.

Seriously, I don’t know who writes this stuff; 23 died in the Scotland outbreak.

Yes, the butchers in both cases made terrible food handling decisions that led to illness and death. But people are going to do dumb, or criminal things with food, which means the overall microbial load must be minimized as food moves from farm-to-fork.

FSA has nothing to say on this.

It is also expected that the guidance will be used by local authority food safety officers when inspecting businesses in their area.

Those inspectors didn’t catch anything at either John Tudor & Sons, or John Barr, the butchers of Wales and Scotland, respectively.

In 1999 Prof Pennington said,

“The prospect of another Mr Barr type situation is still quite real because everybody I talk to in meat inspection and environmental health tells me there are people who are still not doing the right thing.”

So almost 15 years after the Scotland E. coli outbreak, FSA says some of the key measures highlighted in the guidance to control E. coli are:

* identification of separate work areas, surfaces and equipment for raw and ready-to-eat food;
* use of separate complex equipment, such as vacuum-packing machines, slicers, and mincers for raw and ready-to-eat food; and,
* handwashing should be carried out using a recognised technique and anti-bacterial gels must not be used instead of thorough handwashing.

Verifying cooking procedures with tip-sensitive digital thermometers rather than relying on the terrible advice of “until the juices run clear” or “piping hot” would help. But don’t expect FSA to say anything. Maybe in 15 years.
 

If it’s not Scottish, it’s crap; Burns Supper and haggis

In time for tonight’s annual Burns Supper honoring the birth of the Scottish poet Robert Burns, government types have once again invited U.S. regulators to revise a decades-old ban on haggis.

The iconic Scottish dish is been barred in the U.S. because its food safety department prohibits the use of sheep lungs in food products.
 

185 Glasgow eateries failed to meet legal requirements

A total of 185 out of the first 1,200 businesses tested under a new restaurant inspection and disclosure scheme in Glasgow, Scotland, received an ‘Improvement Required’ certificate.

The Evening Times reports that health inspectors suggest to owners that their certificates should be publicly displayed in their premise, although businesses are not required by law to do so.

Which is sorta against the point of disclosure schemes.

Peter Midgley, Head of Enforcement for Scotland at the Food Standards Authority, said the information means diners can make informed choices about where to eat, adding

“It is the owners’ choice if they display their certificate but usually if certificates are being displayed in nearby restaurants, other owners follow.”

Usually, but not always, especially for those diners with lousy inspection results. The system is flawed – make disclosure mandatory.
