    I call Andrew McKenzie a friend, and he calls me a reprobate.

    Fair enough. He certainly dresses better.

    And has more tolerance for meetings.

    Business Day in New Zealand has a profile of the 62-year-old retiring Food Safety Authority chief executive with all the old stories, probably told through certain filters.

    What I remember best – through the fog of good scotch – was an outstanding lamb dinner a pregnant Amy and I had with Andrew and his wife at their home overlooking Wellington in 2008, followed by an All Blacks rugby match on the tube.

    Andrew McKenzie could justly claim the title of the father of modern meat inspection conferred on him by a speaker at a European conference recently.

    The retiring chief executive of the Food Safety Authority was a lowly government official in the mid-80s when he had the temerity to challenge the European-imposed rules governing meat inspection.

    The actions that flowed from this led to savings of many millions of dollars to the meat industry and freed up international trade.

    He encountered his first silly rule as a young Agriculture Ministry meat inspector in the mid-70s. It required the inspectors who worked with meat workers on the slaughter chain to inspect the heads of all sheep to look for signs of disease.

    Dr McKenzie knew this was unnecessary because there were no signs of disease on a head that couldn't already be seen in the normal inspection of the carcass, but it was demanded by Britain as a requirement of accepting our exports.

    The head had to be skinned, adding huge cost to sheep processing. Three or four extra butchers had to be employed on each chain, as well as one extra meat inspector. Ten years later he was in a position to do something about it.

    He convinced the meat companies to run trials. In one day 325,000 animals were killed. No signs of disease were found on the heads that were not already uncovered by inspection of the rest of the carcass.

    He presented the results to the British authorities and they agreed to change the rules.

    It meant the loss of up to 500 seasonal jobs, but the industry estimated its savings at $10 million-$12m a year.

    He went to the European Union headquarters and argued that many of the rules didn't make sense in the New Zealand context. "They asked me to list them. Three days later I came back with 200 examples. When I flopped this on the table, they said `Ah jeez, this is a bit hard'."

    The result was an "equivalency" agreement between Europe and New Zealand.
    "That agrees there's a bunch of basic things you need to do to make a difference to public and animal health, but there's also others that are just good meat manufacturing and hygiene practice and they can vary," he says.

    "Since then our relationship has gone along really well."

    The agreement cleared the way for trade and was used as a template by the United States and Canada.

    Crucial to the ongoing success of the agreement, and those that followed, has been New Zealand's reputation for integrity and honesty in international trade.
    "We've been scrupulously honest and people can rely on our word," Dr McKenzie says.

    "And we're pretty good thinkers – putting new ideas on the table, and taking a lot of their ideas, building on them, trialling them, modifying them and feeding them back into the system."

    That they are, as Katie has just returned from a year working with NZFSA, helping develop a national restaurant inspection disclosure system.

    The New Zealand Food Safety Authority has just released a couple of new food safety advertisements for television.

    Chapman and I looked them over, would have liked a thermometer, and don’t like the message that food safety is simple (otherwise, we wouldn’t all have jobs) but overall the ads seem better than most. As Marshall McLuhan said, those who try to distinguish between entertainment and education don’t know the first thing about either.

    What do you think?

    The organic food isle at the grocery store kind of ticks me off, not that I’m against health food (I’m all for it) but that I don’t have any confidence in the validity of the organic stickers. How do I know these companies are really producing their food in an “organic” way? Is there an organization or regulatory group that investigates these “organic” claims on non-meat products? I’m also quite skeptical of the foods that claim to have extra vitamins/antioxidants or come with a super-duper-nutritious injected-with-vitamins label. Don’t lie to me on the front of your product. Show me the ingredients and I’ll tell you what I think of it.

    There aren’t any laws in place to punish unsubstantiated claims of producing organic foods, but thankfully there are consequences for drugs that make unsubstantiated claims.

    New Zealand brothers John and Ian Fistonich were fined $6,750 for marketing an unregistered herbal horse product with unsubstantiated therapeutic claims.  Their product, Verm-X, claims to repel internal parasites and worms. Not only is there a lack of evidence to validate these claims, but also Verm-X wasn’t registered with the New Zealand Food Safety Authority (NZFSA). Therapeutic products in NZ must be registered under the Agricultural Compounds and Veterinary Medicines (ACVM) Act. ACVM Director Debbie Morris says that “Verm-X has not gone through NZFSA’s rigorous risk assessment and management process to ensure it is safe and does what it says it’s going to do on the label.”

    On the product’s website, Verm-X is praised with its parasitic-controlling herbs, herbs for blood cleansing and also herbs for gut maintenance. They also have a “chemical-free” claim, which is another pet peeve of mine. I’m sure they’re going for the all-natural appeal, but c’mon, everything is made of chemicals.  If it really was “chemical-free” I think it would have a different name like “anti-matter horse dewormer.” But that’s not really the point here. The point is there haven’t been any studies conducted to test the effectiveness of these herbal pellets, and the NZFSA hasn’t cleared Verm-X to be on the market. This includes their horse formulation as well as all the other formulations they have for the rest of the zoo in the backyard.

    Tell us what’s in your product, verify it with the NZFSA and prove your claims. The same goes for therapeutic drugs in the US – make sure you’re a friend of the Food and Drug Administration before putting your product out there.

    Every time there is a food safety outbreak with fresh fruits and vegetables, some journalist or lobby group will call up and say something like, “we want to do some sampling for E. coli or Salmonella and fresh produce.”

    And every time, Chapman or I will walk the person through the limitations with testing, especially in fresh produce.

    New studies by the New Zealand Food Safety Authority (NZFSA) highlight the limitations. In one, two out of 900 samples tested positive for Salmonella in lettuce, both from lettuces from the same grower.

    In a related study, none of the chemical residues detected were of health concern, although NZFSA principal advisor for chemicals Dr Paul Dansted says he is disappointed with results from this year’s Food Residue Surveillance Programme (FRSP), which targets food likely to show up problems. This year’s focus was on spinach, celery, ginger and garlic.

    “A significant number of samples had levels over the maximum residue limit (MRL) which is used for monitoring purposes, but it’s important to stress that dietary intake assessments on the non-compliant food showed none posed a health or food safety concern.”

    Eight out of 27 celery samples and four out of 24 spinach samples had residues that were over the limit. There were none over the limit in 50 samples of garlic, but ginger had 11 samples out of 39 over the limit.

    “Celery and spinach can be more vulnerable to persistence of chemical residues,” Dr Dansted says. “Because of their shape, residues that wash off in the rain can collect in the base of the plant. We expected to find some problems, but this is not good enough. We will take regulatory action to ensure better compliance in future.”


    Properly structured sampling programs are essential to validate that food safety programs are working. But testing is not enough.

    It’s end-of-year, so lists are big, and I’m fond of my Top-5 Records label list.

    But some are just dumb, and it’s good to see the science types in New Zealand calling out some BS.

    The Dominion Post reports tomorrow that toxicologists have accused a food safety campaigner of a lack of understanding after she advised people to eat organic celery to avoid pesticides.

    Alison White has ranked celery at the top of a list of foods likely to contain pesticide residue, but scientists say that does not mean indulging in the vegetable will cause any harm.

    Ms White, who is a researcher and co-convenor of the Safe Food Campaign, said consumers wanted information about whether their food contained pesticide residues.

    Canterbury University toxicology professor Ian Shaw said Ms White's table, which she published on the group's website, displayed "naughtiness" in referencing research about cancer risks among people who sprayed vegetables, not those who ate them.

    Ms White's comments also showed she did not understand the difference between how dangerous a chemical was, and the actual chance or risk of it causing any harm.


    The Food Safety Authority's principal toxicology adviser, John Reeve, dismissed Ms White's suggestion that pesticide residues could be making our food unsafe.

    "Alison White and her colleagues have no expertise in toxicology and don't understand the science."

    Dr Reeve said pesticide limits were determined by how much of a chemical growers needed for it to work.

    That limit was hundreds of times lower than the levels that would have any impact on human health, he said.

    The holidays bring bad food safety advice, and in what’s turning into an annual tradition, it’s time to bash the Brits.

    The Food Standards Agency is hoping to reduce the number of food safety clangers that are served up this Christmas, with its Christmas food safety advertising campaign.”

    WTF is a clanger?

    Oh, Dick van Dyke, is there nothing you can make sound Cockney?

    “The Agency's TV and radio adverts are jovial but have serious underlying messages about the preparation and cooking of turkey:

    don't wash it (you don’t need to)
    defrost it thoroughly
    cook it properly


    That’s terrible grammar; a bulleted list should contain bullets, with semi-colons and an end period. I thought the Brits were serious about this stuff.

    “The Agency’s research has shown that many people wash their turkeys before cooking, with older women the most frequent turkey-washing offenders. But washing meat or poultry can cause harmful food poisoning bacteria to splash on to worktops, chopping boards, dishes and utensils, where they can linger for days.

    “Partially defrosted turkeys are another common festive food safety blunder.”

    This is good stuff: don’t wash the bird, and defrost the thing – notice they don’t say whether it’s OK to do it on the counter or not.

    But then, once, again, with all the food safety communication thingies in the government employ, the best they can come up with is,

    “To ensure that the turkey is cooked properly, make sure it is piping hot all the way through. Cut into the thickest part (between the breast and thigh) to check that none of the meat is pink, and the juices run clear.”

    No. Use a tip-sensitive digital thermometer. Color is a lousy indicator.

    UK chief science thingy, Andrew Wadge, I’ll be in the U.K. Jan. 2 – 10, and I’d be glad to meet with you and your crack food safety risk communication team to talk about turkey prep recommendations.

    From the there’s-an-award-for everything category, the U.K. Food Standards Agency has apparently copped a statue for clear communication about listeria.

    “The Agency has been given an award by the Plain English Campaign for a leaflet advising the over 60s about food safety and the food poisoning bug listeria. Food safety and healthy eating messages are often based on complicated science, but the Agency strives to make these messages as accessible to as many people as possible. We are therefore pleased that these efforts have been recognised by our partners and by the Plain English Campaign.”

    The U.K. government agency that has millions of dollars to engage consumers and the best they can come up with is to serve turkey ‘piping hot’ rather than use a thermometer is now blowing itself for its, ‘Look out for listeria’ campaign. The award-winning leaflet is attached, and it essentially blames old folks for getting listeria.

    The science is not complicated and neither are the communications. The level of state-sponsored arrogance is somewhat alarming.

    Contrary to what the New Zealand Herald reported tonight (this morning in NZ), the animal in question was born in NZ, not the UK, because NZ does not import sheep from the UK.

    MAF Biosecurity New Zealand (MAFBNZ) and the New Zealand Food Safety Authority (NZFSA)
    today confirmed that a series of New Zealand and European laboratory tests on a single New Zealand sheep brain have detected the condition atypical scrapie (also known as Nor 98).

    Atypical scrapie/Nor 98 is a relatively recently discovered brain condition of sheep and goats that is quite different from the classical form of scrapie. 

    Neither atypical scrapie/Nor 98 nor scrapie is known to pose any risk to human health or the safety of eating meat or animal products.


    MAFBNZ Principal International Adviser Dr Stuart MacDiarmid says global knowledge about atypical scrapie/Nor 98 is evolving.  The widely accepted mainstream scientific view is that it occurs spontaneously or naturally in very small numbers of older sheep in all sheep populations around the world.

    “This positive detection of atypical scrapie/Nor 98 in a sheep from New Zealand’s national flock reinforces that view.  Every country that has conducted sufficient surveillance for atypical scrapie/Nor 98 has found it in their flocks.  This includes most Scandinavian and EU countries, the UK, the USA and Canada,” he says.

    The detection does not change New Zealand’s status as free from scrapie.

    Dr MacDiarmid says because of this scrapie freedom status, New Zealand supplies sheep brains to the European Union for use in the development of tests for scrapie. 

    “The affected brain was one of a consignment of 200 brains sent for this purpose.  EU-authorised tests carried out in New Zealand prior to shipment had not picked up anything unusual.  However further tests in Europe and re-testing in New Zealand on different parts of the brain from the area originally tested have now established a diagnosis of atypical scrapie/Nor 98.

    There is no evidence that atypical scrapie/Nor 98 can be transmitted naturally to other animals or to people, or that it in any way affects people.

    Food safety is not simple.

    And because food safety is hard, it’s important to reduce the number of pathogens entering a home or food service kitchen.

    The Food Standards Agency today published the findings of a new survey testing for campylobacter and salmonella in chicken on sale in the U.K.

    The survey showed that campylobacter was present in 65% of the samples of chicken tested. Salmonella was in 6% of samples, 0.5% of these samples contained S. enteritidis and S. typhimurium.

    Andrew Wadge, Director of Food Safety at the Food Standards Agency, said,

    "The continuing low levels of salmonella are encouraging, but it is disappointing that the levels of campylobacter remain high. It is obvious more needs to be done to get these levels down and we need to continue working with poultry producers and retailers to make this happen. Other countries like New Zealand and Denmark have managed to do so, we need to emulate that progress in the UK."

    FSA is to be commended for undertaking the retail survey, but should be slapped on the wrist for terrible risk communication, once again asserting that, “cooking chicken properly all the way through will kill the bug, so consumers can avoid the risk of illness.

    “Taking simple measures in the home can reduce the risk of food poisoning. If food is prepared, handled, and cooked properly, avoiding cross-contamination with other food, then food bugs will not have a chance to spread and cause harm.”


    Food safety is not simple. Piping hot is not an end-point cooking temperature.

    The video below accompanying a terrific N.Y. Times feature on E. coli O157:H7 in ground beef demonstrates how easy it is to cross-contaminate, and they don’t even use a thermometer to ensure delicious 160F hamburgers.

    Organic food is not safer than conventional food. Organic food is not more sustainable than regular food. Organic food is not more nutritious than other food.

    Organic is more expensive than other food, and verification of organic production practices is specious at best.

    Russ Parsons of the Los Angeles Times figured this out a few weeks ago and wrote a column that began,

    "I don't believe in organics."


    This morning he revisited the topic, noted that organics is an article of faith for a lot of people, highlighted some hate mail, and most surprising, revealed that mail supporting Parsons’ column was overwhelmingly positive by a ratio of 5 or 6 to 1.

    This afternoon, the U.K. Food Standards Authority released results of a review it commissioned which found,

    no important differences in the nutrition content, or any additional health benefits, of organic food when compared with conventionally produced food.

    The focus of the review was the nutritional content of foodstuffs.


    Gill Fine, FSA Director of Consumer Choice and Dietary Health, said,

    “Ensuring people have accurate information is absolutely essential in allowing us all to make informed choices about the food we eat. This study does not mean that people should not eat organic food. What it shows is that there is little, if any, nutritional difference between organic and conventionally produced food and that there is no evidence of additional health benefits from eating organic food.”

    The FSA commissioned this research as part of its commitment to giving consumers accurate information about their food, based on the most up-to-date science.

    A paper reporting the results of the review of nutritional differences has been peer-reviewed and published today by the American Journal of Clinical Nutrition.


    Dr Dangour, of the LSHTM’s Nutrition and Public Health Intervention Research Unit, and the principal author of the paper, said:

    “A small number of differences in nutrient content were found to exist between organically and conventionally produced crops and livestock, but these are unlikely to be of any public health relevance. Our review indicates that there is currently no evidence to support the selection of organically over conventionally produced foods on the basis of nutritional superiority.”

    The Times’ Parsons got it right in his original column when he said,

    farming is a complicated enterprise and there is a huge gray area between certified organic and the stereotypical heavy-duty use of chemical pesticides, herbicides and fertilizers.

    Furthermore, a lot of the best farming practices of the original organic philosophy -- composting, fallowing, crop rotation, the use of nonchemical techniques for controlling most pests -- have been adopted by many nonorganic growers, even though they still reserve the right to use chemicals when they think it's best.

    The complete U.K. report is available at http://www.food.gov.uk/multimedia/pdfs/organicreviewreport.pdf
