The plight of Australia’s dairy farmers is on the political agenda this week, after One Nation leader Pauline Hanson narrowly failed in her Senate bid for a minimum milk price. But getting fair payment for their goods is far from the only challenge dairy farmers face.

Pressure has been mounting on the industry for the past decade. Existing milk alternatives are growing their market share, helped by a rise in veganism and public concern around animal welfare. The agriculture sector is under pressure to reduce its contribution to climate change, and technology advances mean milk may one day be produced without cows at all.

All this has been compounded by devastating and prolonged drought. So here’s the full story of the hurdles farmers face, now and in the future, to get milk into your fridge.

Fluctuating farm gate price

The rate at which processors pay farmers for milk is known as the farm gate price. The prices are not regulated and are set by market forces.

In 2016 the milk price crashed when Australia’s two largest dairy processors, Murray Goulburn and Fonterra, lowered the price they would pay from about 48 cents a litre to as low as 40 cents.

This dramatically cut the incomes of milk suppliers. The number of dairy farmers in Australia fell by 600, or 9% over four years. This exit has been exacerbated by drought.

Since then, the farm gate milk price has increased and in 2019–20 is expected to be 51 cents per litre, due to a weaker Australian dollar and demand from export markets. But forecast global prices for butter, cheese and whole milk powder this financial year remain below that of previous years.

Methane, and milk alternatives

Methane and other livestock emissions comprise about 10% of Australia’s greenhouse gas emissions.

As the Intergovernmental Panel on Climate Change made clear in its land use report in August, changes must be made across the food production chain if the world is to keep global warming below the critical 1.5℃ threshold. For beef and dairy livestock, this means changes such as land and manure management, higher-quality feed and genetic improvements. Meeting this challenge cost-effectively, while improving productivity, is no small task.

Crying over plant-based milk: neither science nor history favours a dairy monopoly


Technology may help in curbing greenhouse gas emissions from cows, but it also threatens to replace the dairy industry altogether. Advances in biotech may enable liquid analogous to milk to be produced through bioculture systems, without a cow in sight.

Elsewhere, the rise of plant-based alternatives derived from soybeans, almonds, oats and other sources threatens traditional milk products. This can partly be attributed to increasing numbers of people adopting a vegan diet.

Farmers must overcome a host of challenges to deliver milk to consumers.

Taking calves away from cows

For a mammal to produce milk, it must usually become pregnant and produce offspring. Female calves generally go into a farm’s pool of replacement animals, while male dairy calves are sold.

Pure-breed male dairy calves do not naturally lay down a lot of muscle and so do not generally make good beef livestock. Many are sent to the abattoir for slaughter, typically between 5 and 30 days of age. This practice has prompted welfare concerns and means the industry must carefully manage the handling and transport of vulnerable young calves.

Potential solutions include artificial insemination of cows using only semen that will produce female calves. The use of this technology is limited because it reduces conception rates.

There is also growing public concern about the separation of cows and calves not sent to the abbatoir. The calves are typically taken within the first 12-24 hours and reared together in a shed, where they are fed milk or milk replacer. This is thought to maximise the amount of saleable milk and minimise disease transfer from cow to calf, particularly Johne’s Disease. However, recent research has found little evidence to support these practices.

Research has shown that calf-cow separation in the first day of life causes lower distress than abrupt separation at a few weeks of age or older, when the bond is stronger. This is not to say that early separation is not a concern. Rather, in the face of consumer demands for certain ethical standards, simple fixes may be hard to implement.

The message for consumers

Challenges to the dairy industry will take time and effort to address. Some, such as drought, are out of farmers’ control. Dry conditions and high cost of water, fodder and electricity have forced farmers to cull less productive dairy cows, leading to a decline in production.

Supermarkets are not milking dairy farmers dry: the myth that obscures the real problem


The pressures, and associated debt, create intense stress for farmers, increase family tensions, and have negative flow-on effects throughout rural communities.

Putting aside the political push for a regulated milk price, the key message for dairy consumers is clear. If we want our milk produced in a certain way, we must pay a fair market-based price to cover the costs to farmers of fulfilling our wants.The Conversation

Does eating dairy foods increase your risk of prostate cancer?



If you’re a male who enjoys dairy, there’s no reason to stop having it.

Rosemary Stanton, UNSW

Research Checks interrogate newly published studies and how they’re reported in the media. The analysis is undertaken by one or more academics not involved with the study, and reviewed by another, to make sure it’s accurate.


Recent headlines have warned a diet high in dairy foods may increase men’s risk of prostate cancer.

The news is based on a recent review published in the Journal of the American Osteopathic Association which claimed to find eating high quantities of plant-based foods may be associated with a decreased risk of prostate cancer, while eating high quantities of dairy products may be associated with an increased risk.

But if you’re a man, before you forego the enjoyment and known nutritional benefits of milk, cheese and yoghurt, let’s take a closer look at the findings.

What the study did

This study was a review, which means the researchers collated the findings of a number of existing studies to reach their conclusions.

They looked at 47 studies which they claim constitute a comprehensive review of all available data from 2006-2017. These studies examined prostate cancer risk and its association with a wide variety of foods including vegetables, fruits, legumes, grains, meat (red, white and processed), milk, cheese, butter, yoghurt, total diary, calcium (in foods and supplements), eggs, fish and fats.

Six foods that increase or decrease your risk of cancer


Some studies followed groups of men initially free of prostate cancer over time to see if they developed the disease (these are called cohort studies). Others compared health habits of men with and without prostate cancer (called case-control studies). Some studies recorded the incidence of prostate cancer in the group while others concentrated on the progression of the cancer.

For every potential risk factor, the reviewers marked studies as showing no effect, or an increased or decreased risk of prostate cancer. The results varied significantly for all the foods examined.

For cohort studies (considered more reliable than case-control studies), three studies for vegan diets and one for legumes recorded decreased risk of prostate cancer. For vegetarian diets and vegetables, some reported decreased risk and some recorded no effect. Fruits, grains, white meat and fish appeared to have no effect either way.

An increased risk was reported for eggs and processed meats (one study each), red meat (one out of six studies), fats (two out of five), total dairy (seven out of 14), milk (six out of 15), cheese (one out of six), butter (one out of three), calcium (three out of four from diet and two out of three from supplements) and fats (two out of five).

Notably, some very large cohort studies included in the review showed no association for milk or other dairy products. And most case-control studies, though admittedly less reliable, showed no association.

The authors also omitted other studies published within the review period which showed no significant association between dairy and prostate cancer.

A person’s weight likely has more influence on their risk of developing prostate cancer than whether or not they eat dairy.

So the inconsistency in results across the studies reviewed – including large cohort studies – amount to very limited evidence dairy products are linked to prostate cancer.

Could it be vitamin D?

In earlier research, a link between milk and prostate cancer has been attributed to a high calcium intake, possibly changing the production of a particular form of vitamin D within the body.

Vitamin D is an important regulator of cell growth and proliferation, so scientists believed it may lead to prostate cancer cells growing unchecked. But the evidence on this is limited, and the review adds little to this hypothesis.

PSA testing for prostate cancer is only worth it for some


Perhaps the review’s most surprising omission is mention of the World Cancer Research Fund (WCRF) Continuous Update Project report on prostate cancer. This rigorous global analysis of the scientific literature identified much stronger risk factors that should be considered as possible confounding factors.

For example, the evidence is rated as “strong” that being overweight or obese, and being tall (separate to weight), are associated with increased risk of prostate cancer. The exact reasons for this are not fully understood but could be especially significant in Australia where 74% of men are overweight or obese.

A new Australian study found a higher body mass index was a risk factor for aggressive prostate cancer.

For dairy products and diets high in calcium, according to the WCRF, the evidence remains “limited”.

Why full-fat milk is now OK if you’re healthy, but reduced-fat dairy is still best if you’re not


It’s about the whole diet

It’s not wise to judge any diet by a single food group or nutrient. A healthy diet overall should be the goal.

That being said, milk, cheese and yoghurt are included in Australia’s Dietary Guidelines because of evidence linking them with a lower risk of heart disease, type 2 diabetes, bowel cancer and excess weight. These dairy products are also sources of protein, calcium, iodine, several of the B complex vitamins, and zinc.

Evidence about dairy products and prostate cancer remains uncertain. So before fussing about whether to skip milk, cheese and yoghurt, men who wish to reduce their risk of prostate cancer would be better advised to lose any excess weight. – Rosemary Stanton


Blind peer review

I agree with the author of this Research Check who highlights there is a high degree of variability in the results of the studies examined in this review.

While the authors searched three journal databases, most comprehensive reviews search up to eight databases. Further, the authors did not undertake any assessment of the methodological quality of the studies they looked at. So the results should be interpreted with caution.

Although the authors concluded higher amounts of plant foods may be protective against prostate cancer, the figure presented within the paper indicates more studies reported no effect compared to a decreased risk, so how they came to that conclusion in unclear. For total dairy they present a figure showing there were as many studies suggesting no effect or lower risk as there were showing higher risk.

Importantly, they did not conduct any meta-analyses, where data are mathematically pooled to generate and overall effect across all studies.

As the reviewer points out, many other important sources of high quality data have not been included and there are a number of recent higher quality systematic reviews that could be consulted on this topic. – Clare CollinsThe Conversation

Why full-fat milk is now OK if you’re healthy, but reduced-fat dairy is still best if you’re not



The Heart Foundation now backs full-fat milk if you’re healthy. But it still recommends reduced-fat milk if you have high blood pressure or heart disease.

The Heart Foundation now recommends full-fat milk, cheese and yoghurt or reduced-fat options as part of its updated dietary advice released yesterday.

This moves away from earlier advice that recommended only reduced-fat dairy when it comes to heart health.

So, what’s behind the latest change? And what does this mean for people with high blood pressure or existing heart disease?

According to TV, heart attack victims are rich, white men who clutch their hearts and collapse. Here’s why that’s a worry


What’s new if you’re healthy?

For healthy Australians, the Heart Foundation now recommends unflavoured full-fat milk, yoghurt and cheese, as well as the reduced-fat options previously recommended.

The change comes after reviewing research from systematic reviews and meta-analyses published since 2009. These pooled results come from mostly long-term observational studies.

This is where researchers assess people’s dietary patterns and follow them for many years to look at health differences between people who eat and drink a lot of dairy products and those who consume small amounts.

Researchers run these studies because it is not practical or ethical to put people on experimental diets for 20 or more years and wait to see who gets heart disease.

Are light dairy products better? We asked five experts


So when results of the recent studies were grouped together, the Heart Foundation reported no consistent relationship between full-fat or reduced-fat milk, cheese and yoghurt consumption and the risk of heart disease. The risk was neither increased nor decreased.

Put simply, for people who do not have any risk factors for heart disease, including those in the healthy weight range, choosing reduced-fat or low-fat options for milk, yoghurt and cheese does not confer extra health benefits or risks compared to choosing the higher fat options, as part of a varied healthy eating pattern.

Health Check: is cheese good for you?


Before you think about having a dairy binge, the review noted the studies on full-fat milk, yoghurt and cheese can’t be extrapolated to butter, cream, ice cream and dairy-based desserts.

This is why the Heart Foundation still doesn’t recommend those other full-fat dairy options, even if you’re currently healthy.

What about people with heart disease?

However, for people with heart disease, high blood pressure or some other conditions, the advice is different.

The review found dairy fat in butter seems to raise LDL or “bad” cholesterol levels more than full-fat milk, cheese and yogurt. And for people with raised LDL cholesterol there is a bigger increase in LDL after consuming fat from dairy products.

Got high cholesterol? Here are five foods to eat and avoid


So, for people with high blood cholesterol or existing heart disease, the Heart Foundation recommends unflavoured reduced-fat milk, yoghurt and cheese to help lower their total risk of heart disease, which is consistent with previous recommendations.

Unflavoured, reduced-fat versions are lower in total kilojoules than the full-fat options. So, this will also help lower total energy intakes, a key strategy for managing weight.

Reduced-fat yoghurt and other dairy products are still recommended for people with high cholesterol or existing heart disease.

How does this compare with other advice?

The 2013 National Health and Medical Research Council’s Dietary Guidelines for Australians recommends a variety of healthy foods from the key healthy food groups to achieve a range of measures of good health and well-being, not just heart health.

Based on evidence until 2009, the guidelines generally recommend people aged over two years mostly consume reduced-fat versions of milk, yoghurt, cheese and/or their alternatives, recognising most Australians are overweight or obese.

Plain, Greek, low-fat? How to choose a healthy yoghurt


This advice still holds for people with heart disease. However, the new Heart Foundation advice for healthy people means less emphasis is now on using reduced-fat versions, in light of more recent evidence.

The Australian Dietary Guidelines have a further recommendation to limit eating and drinking foods containing saturated fat. The guidelines recommend replacing high-fat foods which contain mainly saturated fats such as butter and cream, with foods which contain mainly polyunsaturated and monounsaturated fats such as oils, spreads, avocado, nut butters and nut pastes.

This advice is still consistent with the Heart Foundation recommendations.

Australians eat a lot of ‘junk’ food

The most recent (2011-12) National Nutrition Survey of Australians found over one-third (35%) of what we eat comes from energy-dense, nutrient-poor, discretionary foods, or, junk foods.

Poor dietary patterns are the third largest contributor to Australia’s current burden of disease. Being overweight or obese is the second largest contributor, after smoking.

If Australians followed current dietary guidelines, whether using full- or reduced-fat milk, yoghurt and cheese, the national burden of disease due to heart disease would drop by 62%, stroke by 34% and type 2 diabetes by 41%.

What’s the take home message?

See your GP for a heart health check. If you do not have heart disease and prefer full-fat milk, cheese and yoghurt then choose them, or a mix of full and reduced-fat versions.

If you have heart disease or are trying to manage your weight then choose mostly reduced-fat versions.

Focus on making healthy choices across all food groups. If you need personalised advice, ask your GP to refer you to an accredited practising dietitian.The Conversation

Supermarkets are not milking dairy farmers dry: the myth that obscures the real problem


Gary Mortimer, Queensland University of Technology

Australia’s federal agriculture minister, David Littleproud, has called for a boycott of supermarket-branded milk. He is angry about lack of support for a “milk levy” of 10 cents a litre wanted by the dairy industry to support drought-stricken farmers.

Fellow National Party colleagues have called for nothing less than a royal commission into the supermarkets’ support for farmers. Nationals leader, and deputy prime minister, Michael McCormack, has said he is open to the idea.

Amid intense price competition across many supermarket categories, the price of milk stirs passions like nothing else.

But calls to boycott supermarket-branded milk are misguided; and a royal commission would not be money well-spent.

The widely held belief that supermarkets are hurting dairy farmers by driving down the price of milk is incorrect.

It overlooks basic supply chain dynamics and the findings of the 18-month-long inquiry by the Australian Competition and Consumer Commission, which was ordered by then federal treasurer Scott Morrison to investigate the low milk prices paid to dairy farmers.

Indirect relations

Looking at the supply chain for fresh milk helps show why the retail price of supermarket-branded milk does not determine the price paid to farmers as some claim.

There are many players within a food supply chain: producers, processors, wholesalers, retailers and consumers.

Dairy farmers typically sell their milk to processors, who then sell to supermarkets. There is a relationship between the supermarket and processor, not supermarket and farmer. Whether the supermarket sells a litre of milk at $2, $3 or $4 has no direct relationship on the price the processor pays to the farmer.

In the words of the final report of the competition watchdog’s Dairy Inquiry, “the farm-gate price paid to farmers for milk used to fulfil private label milk contracts is not directly correlated with private-label milk retail prices”.

Blame dairy processors

The ACCC’s report does identify a range of market failures due to bargaining power imbalances and information asymmetry, but these are crucially between dairy farmers and processors.

Murray Goulburn and Fonterra are playing chicken with dairy farmers


Dairy farmers’ weak bargaining power means any higher price paid by supermarkets to processors would not necessarily result in higher farm-gate prices. The ACCC report notes that farmers get no more money for the milk that is sold at higher retail prices (such as branded milk).

Processors, not supermarkets, set farm-gate prices in response to market conditions (global and domestic demand), at the minimum level required to secure necessary volumes. Farmers are not paid according to the type or value of the end product their milk is used in. They are paid the same price for their raw milk regardless of what brand goes on the container.

ACCC Dairy Inquiry

Also blame consumers

Supermarkets are under pressure to keep food prices low, particularly on staples such as bread, milk and eggs. This is evident from the fact that campaigns to get shoppers to exercise their power as ethical consumers quickly run out of steam.




Read more:
We are what we eat: the demise of the ethical grocery shopper


In April 2016, for example, national attention on the plight of dairy farmers led to a campaign encouraging shoppers to leave “supermarket branded milk” on the shelves. In a single month the supermarket brands’ share of milk sales dropped from 66% to 51%. Then it began to rise again. Within a year it was back to nearly 60%.


https://datawrapper.dwcdn.net/NyTIZ/1/


Adding to confusion

While a milk levy to directly help farmers during the drought has many supporters, the disconnect within the supply chain means it is near impossible for retailers to pass the money directly to the intended beneficiaries. That, again, depends on those who buys the milk from the farmers – the processors.

Despite this, and because the ACCC inquiry’s findings have so far done little to dispel myths about the price of milk, retailers such as Woolworths have seen it as prudent to embrace the levy idea and publicly demonstrate support for dairy farmers.

Time to get regulation back into Australian dairy?


All the additional proceeds from its “Drought Relief” milk go back to processor Parmalat, who is responsible for distributing the money to suppliers in drought-affected areas. Coles, meanwhile, has slapped a 30 cent levy on its three-litre milk containers, with the funds going to the Coles Drought Relief Fund.

These measures arguably add to continuing confusion about how the milk market works and the relationship between farm-gate and retail prices.

In the court of public opinion the supermarkets probably had no option but to go along with the charade.

A minister for agriculture, however, should know better.The Conversation

ISRAEL: MESSIANIC JEW WINS SUPREME COURT BATTLE


Bakery owner had lost her Jewish dietary law certificate because of her faith.

JERUSALEM , July 15 (Compass Direct News) – For three long years a Jewish believer in Christ struggled to keep her bakery business alive after the Chief Rabbinate of Israel, the country’s highest religious governing body, annulled her kashrut (Jewish dietary law) certificate because of her faith.

Pnina Conforti, 51, finally gave a sigh of relief when the Israeli Supreme Court on June 29 ruled that her belief in Jesus Christ was unrelated to her eligibility for a kashrut certificate. While bakeries and restaurants in Israel are not required to obtain such a permit, the loss of one often slows the flow of customers who observe Jewish dietary laws and eventually can destroy a business.

Conforti said that the last three years were very difficult for her and her family, as she lost nearly 70 percent of her customers.

“We barely survived, but now it’s all behind us,” she said. “Apparently, many people supported us, and were happy with the verdict. Enough is enough.”

Conforti, who describes herself as a Messianic Jew, had built her Pnina Pie bakeries in Gan Yavne and Ashdod from scratch. She said her nightmare began in 2002 with an article about her in “Kivun,” a magazine for Messianic Jews in Israel.

“Soon after, the people of the Rabbinate summoned me and told me that my kashrut certificate was annulled because I do not profess Judaism,” she said.

Food prepared in accordance with kashrut guidelines is termed kosher, from the Hebrew kasher, or “fit,” and includes prohibition of cooking and consuming meat and diary products together, keeping different sets of dishes for those products, and slaughtering animals according to certain rules. News of the faith of the owner of the Pnina Pie bakery in Gan Yavne spread quickly, soon reaching extremist organizations such as Yad le’Achim, a sometimes violent Orthodox Jewish group.

“They spread around a pamphlet with my photo, warning people away from acquiring products from my business,” Conforti said. “One such a pamphlet was hung in a synagogue. However, I refused to surrender to them and continued working as usual.”

Four years later, in 2006, Conforti decided to open another patisserie in Ashdod, near her original shop in Gan Yavne, in southern Israel. The business flourished, but success didn’t last long.

“A customer of mine, an Orthodox Jew from Ashdod, visited his friends and relatives in Gan Yavne,” she said. “There in the synagogue he came across a pamphlet from 2002 with my photo on it. In addition to boycott calls, I was also described as a missionary. My customer confronted me, and I honestly told him I was a believer.”

Soon thereafter the Rabbinate of Ashdod withdrew the kashrut certificate from her shop there, she said.

“Pamphlets in Hebrew, English and French about me begun circulating around the town,” Conforti said. “They even printed some in Russian, since they saw that the customers of Russian origin continue to arrive.”

The withdrawal of the certificate from the shop in Ashdod in 2006 was a serious blow to her business. Conforti decided to take action, and her lawyer appealed to Israel’s Supreme Court. Judges Yoram Denziger, Salim Jubran and Eliezer Rivlin ruled that the Chief Rabbinate of Israel overstepped its authority.

“The Kashrut Law states clearly that only legal deliberations directly related to what makes the food kosher are relevant, not wider concerns unrelated to food preparation,” the panel of judges wrote.

In response, the Chief Rabbinate accused the judges of meddling in religious affairs.

Soon after she petitioned the Supreme Court, Conforti said, the Chief Rabbinate had offered her a deal by which it would issue her business a kashrut certificate but with certain restrictions, such as handing the keys of the bakery to a kashrut supervisor at night. Conforti declined.

Tzvi Sedan, editor-in-chief of “Kivun,” said the Supreme Court verdict was paramount.

“It’s important not only for Messianic Jews, but also for every other business owner who has to suffer from the arbitrariness of the Rabbinate,” Sedan said. “But I still want to see this decision implemented fully in reality.”

At press time Conforti still hadn’t received the certificate. She was waiting for a team of inspectors from the Rabbinate to inspect the business prior to issuing her the certificate.

A Jew of Yemenite origin, Conforti said she was raised in religious family but came to trust in Christ following her encounter with a Christian family during a visit to the United States.

“There I found Christ and embraced him as my personal Savior,” she said. “I do not engage in [evangelistic] activity, but if someone starts a conversation about my faith, I will speak openly about it.”
