Lean fish has significant advantages over other aquatic or terrestrial species for cell-cultured protein production, according to the founders of Clean Research, a new open science initiative created to accelerate the research and development of cell-cultured fish.
Is the "ugly produce'" trend already reaching the end of its shelf life in supermarkets?Walmart and Whole Foods in recent years tried selling some blemished fruits and vegetables at a discount, produce they said might otherwise be trashed because it's not quite the right size, shape or color. But the two chains and others quietly ended their tests, suggesting dented apples and undersized potatoes may not be all that appealing in stores where better looking fruits and vegetables are on display."Customers didn't accept it as much as we had hoped," said Mona Golub of Price Chopper, a grocery chain in the Northeast that also discontinued its offering of ugly produce.
Salmon aren’t supposed to be swimming here. The lettuce, spinach and other leafy greens also are out of place.A 3-acre greenhouse, nearly twice the length of a football field, glows purple from its more than 1,100 LED grow lights — a sight that turns the heads of passing motorists on Interstate 94 at night. The lights, with cloud-based software, help mimic California’s Salinas Valley.Next door, the North Atlantic Ocean is replicated in a one-acre fish house. Thousands of Atlantic salmon, some newly hatched from eggs sourced in Iceland, others nearly 10 pounds after two years, are raised in 22,000-gallon tanks filled with fresh water drawn from a 180-foot-deep well.About 95 percent of the Atlantic salmon consumed in the U.S. is imported, primarily from Norway and Chile, while about 90 percent of the lettuce grown in the U.S. comes from traditional farm fields, mainly in California and Arizona.But just up the hill from an abandoned schoolhouse in the rolling hills of west central Wisconsin about 33 miles southeast of Eau Claire, 3,000 to 4,000 pounds of salmon are harvested each week and 1.5 million pounds of leafy greens each year. And it’s all being sold to grocers, restaurants and wholesalers within a 400-mile radius of Jackson County.
Farmers, ranchers, fisherman and the rest of agribusiness will try to satisfy dietary protein demands as the global population soars in number toward the nine billion the United Nations projects by 2040. With that steady increase comes rising incomes and, especially in developing countries, demand for more and more protein-laden foods. How to meet the demand? Boundless possibilities emerge, butting up against the array of challenges of bringing protein foods to market — the shrinking bases of arable land base and fresh water, for example, plus climate change, concern about animal agriculture’s environment impacts, animal rights issues, and more. Meat and dairy substitutes are already landing on our dietary shores with a thump.Rabobank estimated retail sales of plant-based meat alternatives had risen by almost one-quarter to an estimated $770 million in the twelve months up to August 2018,” and “the wider range of plant-based alternatives to conventional animal foods (including milk, cheese, yogurt, etc.) ... up 17 percent in the past twelve months. Equally impressive are the number of new entrants and players in the “new protein landscape.”
The Tennessee Senate Commerce and Labor Committee has yet to schedule a hearing on the Briggs bill, but what lawmakers are hearing is that Senate Bill (SB) 15 pits community health against civil liberties.Briggs, is a Republican, a cardiac surgeon and a retired U.S. Army Colonel. He represents Knoxville in the Tennessee Senate, told Ohio television station WTOL Channel 11 that the controversy his bill has caused is like “kicking a hornet’s nest.” Raw milk dairy farmers are fighting for their loophole, saying civil liberties are at stake for both producers and consumers of raw milk. They are calling opposition to the Briggs bill “a liberty issue.” Briggs decided to take on the cow-share loophole after an E. coli outbreak this past summer in Knox County sickened 10 children, some severely. Raw milk produced by French Broad Farm was the likely cause of the outbreak, according to investigators. The dairy ended its cow-share program in response to the event.
Food that is lost before it reaches the consumer, and food that is wasted by consumers, has been estimated to account for as much as 40% of the total food produced in the United States (Buzby, Wells, and Hyman, 2014; Hall et al., 2009). This represents losses of important resources—including water, chemical inputs, and labor—as well as unused nutrients for consumers. Stakeholders along the supply chain are increasingly interested in developing improved approaches to measuring food waste, understanding its determinants, and devising strategies to ultimately reduce it. To date, a majority of food waste studies have focused on household-level waste; fewer studies have examined waste in food distribution and retail settings, and very little work has been conducted to understand the economic causes and consequences of food loss at the farm level. This Choices theme presents a collection of articles that explore food loss and food waste in the context of the U.S. food supply chain. The behavior and incentives of a variety of food system stakeholders including producers, market intermediaries (including retailers), and consumers are considered. The articles are organized along the supply chain, beginning with upstream issues of food loss proceeding through downstream topics such as household decisions concerning when to discard food. Taken together, this collection offers intriguing insights into current frontiers of the myriad private and public efforts to better characterize, quantify, and reduce food waste.
Researchers describe two late Neanderthals with exceptionally high nitrogen isotope ratios, which would traditionally be interpreted as the signature of freshwater fish consumption. By studying the isotope ratios of single amino acids, they however demonstrated that instead of fish, the adult Neanderthal had a diet relying on large herbivore mammals and that the other Neanderthal was a breastfeeding baby whose mother was also a carnivore.
A new study claims an organic diet can significantly reduce pesticide levels, but the research doesn’t hold up.Published February 12 in the journal Environmental Research, the authors of the study tested pesticide levels in the urine of 16 study participants, before and after switching to an organic diet, and found pesticide levels decreased after the switch. But there’s more to the story. The study primarily tested for the kinds of pesticides allowed in conventional agriculture, and not the pesticides allowed on organic farms. So what the study actually shows is fairly obvious: people won’t flush out what they aren’t eating.The study also doesn’t say anything about whether there’s ahealth risk associated with conventional pesticide residues, since the mere presence of a chemical in urine isn’t necessarily an unhealthy or dangerous sign.
Researchers are looking for alternatives to traditional meat because farming animals is helping to drive up global temperatures. However, meat grown in the lab may make matters worse in some circumstances. Researchers say it depends on how the energy to make the lab meat is produced.This is because the emissions from the lab are related to the production of energy which is almost entirely made up of carbon dioxide, which persists in the atmosphere for hundreds of years.This is because the emissions from the lab are related to the production of energy which is almost entirely made up of carbon dioxide, which persists in the atmosphere for hundreds of years."Artificial meat may result in the presence of organic or chemical molecule residues in water, because the process would need to produce huge amounts of chemical and organic molecules, such as hormones, growth factors, to add to the culture medium to grow the meat" said Prof Jean-Francois Hocquette, at the French National Institute for Agricultural Research.
Brucella bacteria in raw milk from Miller's Biodiversity Farm in Quarryville, Pa., has affected an "unknown number" of people in 19 states, according to the CDC. RB51, the strain of brucella found in the milk, is resistant to the antibiotic rifampin.
