RFK Jr may have lied to the Senate about vaccines, but it is now evident that he also lied to his supporters about getting toxic chemicals out of the food supply.

Let’s start here: 

Well, it wasn’t his USDA (he’s Secretary of HHS), apparently.

Now we have President Trump’s executive order: PROMOTING THE NATIONAL DEFENSE BY ENSURING AN ADEQUATE SUPPLY OF ELEMENTAL PHOSPHORUS AND GLYPHOSATE-BASED HERBICIDES.

There is no direct one-for-one chemical alternative to glyphosate-based herbicides.  Lack of access to glyphosate-based herbicides would critically jeopardize agricultural productivity, adding pressure to the domestic food system, and may result in a transition of cropland to other uses due to low productivity.  Given the profit margins growers currently face, any major restrictions in access to glyphosate-based herbicides would result in economic losses for growers and make it untenable for them to meet growing food and feed demands.

Never mind the multiple independent research studies and judgment by cancer experts of the World Health Organization that glyphosate is potentially carcinogenic (see account in The New Lede).

Never mind that Bayer, which bought Monsanto and now owns glyphosate, just said it would put $7.5 billion into settling lawsuits over it.

Never mind that glyphosate is in everything, including bread.

Hypocrisy alert: RFK Jr now says he supports the president’s decision on glyphosate.

And now, RFK Jr’s defense posted on X:

Unfortunately, our agricultural system depends heavily on these chemicals. The U.S. represents 4% of the world’s population, yet we use roughly 25% of its pesticides. If these inputs disappeared overnight, crop yields would fall, food prices would surge, and America would experience a massive loss of farms even beyond what we are witnessing today. The consequences would be disastrous.

Disastrous for whom, exactly?

A recent study finds pasteurization of milk to be an effective preventive measure against avian influenza in mice.

We found that milk pasteurization fully inactivated pandemic H1N1 and bovine H5N1 influenza viruses yet preserved hemagglutinin (HA) protein integrity. In mice, repeated oral exposure to inactivated virus did not alter mortality after H5N1 virus challenge.

This is excellent news.  It means that the risk of getting bird flu from pasteurized milk is extremely low.

Bird flu is increasingly widespread in dairy cattle.

The CDC says the risk to humans is low, but 71 cases have been observed so far, with one death.

The situation with bird flu is one more reason to expect bettter safety from pasteurized than raw milk.

The FDA continues to say that pasteurized milk is safer.  Its page on raw milk offers these links.

• Food Safety and Raw Milk
• The Dangers of Raw Milk: Unpasteurized Milk Can Pose a Serious Health Risk
• Questions & Answers: Raw Milk
• Raw Milk Misconceptions and the Danger of Raw Milk Consumption

The FDA reports that from 1998 through 2018, there were 202 outbreaks linked to drinking raw milk, which caused 2,645 illnesses and 228 hospitalizations.

This is a lot or not, depending on point of view, but all were likely to have been prevented by pasteurization.

The Raw Milk Institute insists on the benefits of raw milk.

My assessment: there may be benefits, but they are marginal.  There are safer ways to improve immunity.

The risks of raw milk may be infrequent, but when it comes to milk, I’d rather play it safe.

As the WHO/UNICEF report I posted yesterday makes clear, the marketing of infant formula—impossible for new mothers to avoid—interferes with breast feeding and, therefore, is a public health concern.

I posted about the Abbott Labs infant formula recall last week.

Here are some additional items I’ve collected on this topic.

I.  What the marketing looks like.

II.  Study finds no benefit of enriched infant formula on later academic performance: Children who are given nutrient or supplement enriched formula milk as babies do not appear to have higher exam scores as adolescents than those fed with standard formula, suggests a study published by The BMJ, leading researchers to argue renewed regulation is needed to better control infant formula promotional claims….

III.  IBFAN, the International Baby Foods Action Network, writes that it is:

launching a PETITION calling for an immediate halt to a new study  –  funded by the Gates Foundation and led by researchers from the University of California – that is randomly allocating infant formula to breastfeed in low-birth-weight babies in Uganda and Guinea-Bissau on assumption that this might prevent wasting and stunting.

The study, which has been cleared by ethics committees in the USA, Uganda and Guinea -Bissau – uses purchased ready-to-use infant formula made by Abbott, a US pharmaceutical corporation operating in 160 countries.  Abbott is a major violator of the International Code and is currently at the centre of a media storm in the USA because of contamination in its powdered formula. (NB. The formula used in the trial is liquid Ready-to-Feed).

IV.  IBFAN issued an earlier statement: The baby food industry’s destruction of an irreplaceable natural resource.

The International Code of Marketing of Breastmilk Substitutes was adopted forty years ago by the World Health Assembly, the world’s highest health policy setting body…Today 70% of countries have adopted laws based on the Code, however far too many are limited in scope and full of loopholes as a result of industry interference. As a consequence predatory marketing of baby food products continues throughout the world.  and the global Baby Food Drink Market is forecast to rise more than 30% in 5 years (from $68bn in 2020 to $91.5bn by 2026)….Aside from its crucial role in child survival (more than 800,000 children die each year because they are not breastfed and many more do not reach their full potential, ­­ breastfeeding is the most environmentally friendly way to feed an infant, resulting in zero waste, minimal greenhouse gases, and negligible water footprint. As a renewable natural food resource, mother’s milk makes an important contribution to local food and water security.…the baby food industry lost no time in exploiting the fear and confusion during the pandemic: falsely claiming their products build immunity; that their  ‘donations’ are humanitarian; encouraging the needless separation of mothers and babies and pretending that they are essential ‘partners’ who are genuinely working to address the problems.

V.  The Access to Nutrition Initiative (ATNI) assesses nine formula companies’ adherence to WHO recommendations.  Its report is here.

According to its press release,

Despite the World Health Assembly (WHA) adopting ‘The International Code of Marketing of Breast-milk Substitutes’ forty years ago and passing 18 associated resolutions since (collectively referred to as ‘The Code’), the BMS/CF Marketing Index 2021 found that none of the companies it assessed fully abides by The Code’s recommendations and most fall well short.

The summary: 

• Danone retained first place with a score of 68%, up from its 2018 score of 46%
• Nestlé, the market leader in sales value, retained its second place with a score of 57% – also a substantial improvement on its score of 45% in 2018
• KraftHeinz achieved the greatest improvement, ranking third, with a score of 38% compared to in 2018 when it didn’t score at all
• Reckitt (previously RB) substantially improved its BMS Marketing policies which led to a big jump in its score from 10% in 2018 to 32% in 2021 and climbing one place to fourth in the ranking.

VI.  A study: Conflicts of interest are harming maternal and child health: time for scientific journals to end relationships with manufacturers of breast-milk substitutes.  Pereira-Kotze C, et al.  BMJ Global Health. 2022 Feb;7(2):e008002. doi: 10.1136/bmjgh-2021-008002

The promotion and support of breastfeeding globally is thwarted by the USD $57 billion (and growing) formula industry that engages in overt and covert advertising and promotion as well as extensive political activity to foster policy environments conducive to market growth. This includes health professional financing and engagement through courses, e-learning platforms, sponsorship of conferences and health professional associations and advertising in medical/health journals…journal publishers may consciously, or unconsciously, favour corporations in ways that undermine scientific integrity and editorial independence—even perceived conflicts of interest may tarnish the reputation of scientists, organisations or corporations.  Such conflicts have plagued infant and young child nutrition science for decades.

Comment: As I mentioned yesterday, we now have more than enough evidence to put a stop to this.

What got my attention was this headline: The World’s Deadliest Pig Virus Creeps Closer to the U.S.

The Western Hemisphere registered its first outbreak of African swine fever virus in almost 40 years on July 28 at pig farms in the Dominican Republic. By September the devastating disease had been found in neighboring Haiti. Now the U.S., the world’s largest pork producer after China, is scrambling to keep the malady from washing ashore and shutting down its $7.7 billion pork export industry.

Unless you are a pig farmer, you probably don’t know much about this disease.  According to the USDA, 

African swine fever is a highly contagious and deadly viral disease affecting both domestic and feral swine of all ages. ASF is not a threat to human health and cannot be transmitted from pigs to humans. It is not a food safety issue…It has never been found in the United States – and we want to keep it that way.

Why?

ASF is a devastating, deadly disease that would have a significant impact on U.S. livestock producers, their communities and the economy if it were found here. There is no treatment or vaccine available for this disease. The only way to stop this disease is to depopulate all affected or exposed swine herds.

“Depopulate” is a euphemism for slaughtering the pigs.  Hence the concern about its likely entry into the U.S.

I get an almost daily newsletter, African Swine Fever Update with frequent updates on where the virus is doing its worst.

But now hopeful news: USDA’s ASF vaccine candidate successful in tests

USDA has been working on a vaccine and just announced its success.

Newly published USDA research, as highlighted in the journal Transboundary and Emerging Diseases, shows that ARS scientists have developed a vaccine candidate with the ability to be commercially produced while still maintaining its vaccine efficacy against Asian ASFV strains when tested in both European and Asian breeds of swine…The onset of immunity was revealed in approximately one-third of the swine by second week post-vaccination, with full protection in all swine achieved by the fourth week.

So, Covid vaccines for us, ASF vaccines for pigs. Let’s go for both!

I’m always interested in how the food industry tries to sell products to specific groups.  Here’s one of FoodNavigator’s Special Editions (collections of articles) on products the food industry is designing and trying to sell for older adults.

Special Edition: Healthy ageing: Food for an older population

Europe is ageing. By 2050 the population of over 65s is expected to reach almost 150m in the region. Gains are expected for products that cater to this older demographic by boosting immunity, as well as bone, joint, muscle, cognitive, heart, skin, eye and digestive health. FoodNavigator looks at some of the innovation strategies food makers are developing to meet the needs of older people.

Food Safety News reports that the European Commission is getting increasingly upset about fraudulent claims that specific food and supplement products will boost immunity and help protect against Covid-19 or even cure it.

Alas, they will not.

The EC is worried about online advertisements.  Food Safety News reported more than 350 cases of such claims in June.  Now there are even more.

In the US, we mostly see this sort of thing—websites from the supplement industry telling you to take supplements.  Here  is what this one claims, with my comments in red.

Supplements can help you address nutrient insufficiencies or deficiencies in your diet—but can they help you fight COVID-19? Not as far as anyone knows.

While there hasn’t been specifically-targeted research to determine which—if any—nutrients should be FDA-approved to ward off the virus, [Indeed] supplements are an ideal way to keep your body and your immune system functioning at optimal levels. No, they are not.  Food works much better.

As a result, many physicians and other health and wellness experts recommend beginning a simple supplement routine to ensure your body has the nutrients it needs to stay healthy.  Many others do not, and neither do I.…The supplements you take during the COVID-19 pandemic may not be specifically developed to ward off the coronavirus. Right.  So don’t expect them to work.

Still, research has shown that they all play an important role in boosting the immune system, preventing respiratory damage, strengthening the body against viral infections, reducing inflammation—or all of the above.  This is true, but largely in experimental studies likely to have been funded by the supplement industry.

Obviously, I am not a fan of supplements.  There just isn’t much evidence that they do anything useful for healthy people, and healthy people are the ones most likely to be taking them.

With respect to Covid-19, the best preventive strategy is avoidance (masks, distancing, etc).

The best immune-boosting strategy is to eat a healthy diet–largely (but not necessarily exclusively) plant-based, balanced in calories, and with minimal amounts of ultra-processed junk foods.

And let’s all hope the vaccination comes soon and works like a charm.

Happy holidays.

Everybody loves chocolate but there’s a lot about its production that’s not to love.  It is a classic example of an exploited commodity: cocoa is grown in developing countries, sold at low cost, and processed in industrialized countries which reap the profits.

Chocolate producers are under pressure (not enough, in my view) to pay farmers decently and to make sure their kids go to school, not work.

I’ve been seeing a lot of articles about these issues lately.   You can see what the issues are just from their headlines:

These are long-standing issues.  They should have been addressed more effectively years ago.   Here is some background reading:

  • Washington Post: Cocoa’s child laborers
  • Fortune: Big Chocolate’s Child Labor Problem is Far From Fixed

I know I’ve talked about what foods are safe to eat earlier (see previous post), but from the number of queries I’m getting it’s clear that this matter needs further discussion.

I can understand why this is so confusing.  Nobody gives a straight answer.

Let me start with the CDC’s advice:

How’s that for reassuring?

Consumer Reports: Answers to Common Questions About Coronavirus and the Food You Eat

The CDC, the Food and Drug Administration, the Department of Agriculture, and the World Health Organization say that food is not known to be a route of transmission of the virus. And the information available from outbreaks of SARS and MERS, caused by coronaviruses similar to the one that causes COVID-19, is reassuring. According to the WHO, the evidence showed that those illnesses were not transmitted by food.

Seattle Times: Debunking 10 myths about the Coronavirus

MYTH: The coronavirus can’t survive airborne or on surfaces.

FACT: Researchers have found that droplets carrying the virus can travel through the air and stay suspended for about half an hour. They can also settle on surfaces, where the virus can last longer — up to 24 hours on cardboard and up to 72 hours on plastic and steel. The risk of getting infected from touching these materials, however, remains low because the virus’ ability to infect decreases rapidly over time.  Source: The New York Times

Washington Post: Why health experts aren’t warning about coronavirus in food

The CDC and other experts note that the virus is new and still being studied. But they say there’s no evidence yet that COVID-19 sickens people through their digestive systems, though the virus has been detected in the feces of infected people.

Washington Post:  Grocery shopping during the coronavirus: Wash your hands, keep your distance and limit trips

In my paraphrasing:

• Don’t go to the grocery store unless you have to
• Wear a face mask

JAMA’s Patient Page on food safety and the virus

My bottom line on how to interpret all this

Maybe this virus has not been shown to be transmitted through food—yet—but why be the first case.  While waiting for the research—and let’s hope it comes soon—following the Washington Post’s and JAMA’s advice makes sense.

It’s also always a good idea to follow basic food safety principles for raw foods: clean, cook, separate, chill.

Cooking kills the virus.  Enjoy!

Have a happy, well fed, and safe weekend.
