Listened to Food safety and industry concentration: How the back seat of a car is like a bag of leafy greens by Jeremy Cherfas from Eat This Podcast

In the previous episode, I talked to Phil Howard of Michigan State University about concentration in the food industry. Afterwards, I realised I had been so taken up with what he was telling me that I forgot to ask him one crucial question.

Is there any effect of concentration on public health or food safety?

It seems intuitively obvious that if you have long food chains, dependent on only a few producers, there is the potential for very widespread outbreaks. That is exactly what we are seeing in the current outbreaks of dangerous E. coli on romaine lettuce and Salmonella in eggs. But it is also possible that big industrial food producers both have the capital to invest in food safety and face stiffer penalties when things go wrong.

Are small producers and short food chains better? Marc Bellemare, at the University of Minnesota, has uncovered a strong correlation between some food-borne illnesses and the number of farmers’ markets relative to the population.

Phil thinks one answer is greater decentralization. There’s no good reason why all the winter lettuce and spinach in America should come from a tiny area around Yuma, Arizona. Marc says consumer education would help; we need to handle the food we buy with more attention to keeping it safe. Both solutions will take quite large changes in behaviour, by government and by ordinary people.

Right now, it probably isn’t possible to say with any certainty whether one system is inherently safer than the other. But even asking the question raises some interesting additional questions. If you have answers, or even suggestions, let me know.

Notes

  1. Phil Howard’s work on food-borne illness is on his website.
  2. Marc Bellemare’s work on farmers’ markets and food-borne illness has gone through a few iterations. He’ll email you a copy of the final paper if you ask.
  3. An episode early last year looked at aspects of food safety in developing countries. Spoiler: shorter food chains are safer there.
  4. Banner photo, norovirus. Cover photo, E. coli. Both public domain to the best of my knoweldge.
I can’t help but think about analogizing the mass production and distribution of food to that of social media (again). Replace food producers with social media and you’ve got large mega-producers like Facebook and Twitter at one end and smaller scale indie producers at the other. Surely outbreaks of issues with democracy, bulllying, racism, doxxing, etc. will happen all around, but when they happen on the larger platforms, then far more people are affected.

From an economic standpoint it would be nice to have more significant studies to see what the overall pieces of large and small producers are (as well as for the distribution piece too). What is the ultimate equilibrium point for overall cost versus public health? What would it look like theoretically?

Two of my favorite topics: Food and Science!

The University of East Anglia in the UK in association with the Institute of Food Research is offering a free four week course Identifying Food Fraud.  It’s an introduction to modern analytical science techniques and how they can be used to uncover food fraud.

Identifying Food Fraud

I know many people who could identify a fake Louis Vuitton (LVMH) purse, a knock off Christian Louboutin, or a sham Rolex, but who simultaneously are overly religious about their food brands and topics like organic food and couldn’t similarly identify the fakes they’re eating because of fraud in food labeling and misdirection and legerdemain within the food supply chain.  Finally there’s a course to help everyone become smarter consumers.

The food industry is one of the most important commercial sectors in the world. Everyone uses it, but how many people abuse it? As we witness the increasing globalisation of the supply chain, a growing challenge is verifying the questionable identity of raw materials in the food we eat.

In this course we will look at topical issues concerning ‘food fraud’ and explore ways in which analytical chemistry can help in its identification and prevention. We’ll share fascinating examples, such as the history of white bread and a surprising ingredient once found in bitter beer.

The University of East Anglia has joined forces with the world-renowned Institute of Food Research (IFR) to bring you this unique course. You’ll be led by Kate Kemsley, a specialist in the use of advanced instrumentation for measuring the chemical composition of food materials. Course content is linked with UEA’s MChem postgraduate programme, which supports final-year students’ practical research projects in this area of science.

For those interested the course starts on October 26, 2015.
