GLOBAL MEAT NEWS
Lab-grown meat producer Memphis Meats has announced the production of the world’s first ‘clean’ chicken and duck.
While a few companies, including Memphis Meats, have produced clean – commonly known as lab-grown – beef, it is believed that this is the first time clean poultry has been created.
“It is thrilling to introduce the first chicken and duck that didn’t require raising animals. This is a historic moment for the clean meat movement,” said Uma Valeti, co-founder and CEO of Memphis Meats. “Chicken and duck are at the centre of the table in so many cultures around the world, but the way conventional poultry is raised creates huge problems for the environment, animal welfare, and human health. It is also inefficient.
“We aim to produce meat in a better way, so that it is delicious, affordable and sustainable. We really believe this is a significant technological leap for humanity, and an incredible business opportunity — to transform a giant global industry while contributing to solving some of the most urgent sustainability issues of our time.”
Clean meat production rise
Memphis Meats’ poultry breakthrough was made possible by a new procedure that the company is developing to produce new clean meat products and accelerate clean meat innovation.
The multi-animal platform is expected to allow the company to produce many types of meat and to fine-tune the taste, texture and nutrition profile of its products. The platform will also enable the company to scale up production and rapidly reduce costs.
The team expects to continue reducing production costs dramatically, with a target launch of its products to consumers by 2021. Continue Reading →

A team of Chinese scientists will be the first in the world to apply the revolutionary gene-editing technique known as Crispr on human subjects. Led by Lu You, an oncologist at Sichuan University’s West China hospital in Chengdu, China, the team plan to start testing cells modified with Crispr on patients with lung cancer in August, according to the journal Nature. Crispr is a game-changer in bioscience; a groundbreaking technique which can find, cut out and replace specific parts of DNA using a specially programmed enzyme named Cas9. Its ramifications are next to endless, from changing the color of mouse fur to designing malaria-free mosquitoes and pest-resistant crops to correcting a wide swath of genetic diseases like sickle-cell anaemia in humans. The concept of editing human DNA has often been controversial. Continue Reading →

Two men with progressive blindness have regained some of their vision after taking part in the first clinical trial of a gene therapy for the condition. The men were among six patients to have experimental treatment for a rare, inherited, disorder called choroideremia, which steadily destroys eyesight and leaves people blind in middle age. After therapy to correct a faulty gene, the men could read two to four more lines on an optician’s sight chart, a dramatic improvement that has held since the doctors treated them. One man was treated more than two years ago. The other four patients, who had less advanced disease and good eyesight before the trial, had better night vision after the therapy. Continue Reading →

Scientists in Britain have been give the go-ahead to edit the genes of human embryos for research purposes, using a technique that some say could eventually be used to create “designer babies”. Less than a year after Chinese scientists caused an international furor by saying they had genetically modified human embryos, Kathy Niakan, a stem cell scientist from London’s Francis Crick Institute, was granted a license to carry out similar experiments. “The Human Fertilisation and Embryology Authority (HFEA) has approved a research application from the Francis Crick Institute to use new ‘gene editing’ techniques on human embryos,” Niakan’s lab said on Monday. It said the work carried out “will be for research purposes and will look at the first seven days of a fertilized egg’s development, from a single cell to around 250 cells”. The scientists will not be allowed to develop the modified embryos for clinical purposes or implant them into any women. Continue Reading →
Elizabeth Parrish, CEO of Bioviva USA Inc. has become the first human being to be successfully rejuvenated by gene therapy, after her own company’s experimental therapies reversed 20 years of normal telomere shortening. Telomere score is calculated according to telomere length of white blood cells (T-lymphocytes). This result is based on the average T-lymphocyte telomere length compared to the American population at the same age range. The higher the telomere score, the “younger” the cells. In September 2015, then 44 year-old CEO of BioViva USA Inc. Elizabeth Parrish received two of her own company’s experimental gene therapies: one to protect against loss of muscle mass with age, another to battle stem cell depletion responsible for diverse age-related diseases and infirmities.

Cutting-edge gene-editing techniques have produced an unexpected byproduct — tiny pigs that a leading Chinese genomics institute will soon sell as pets.
BGI in Shenzhen, the genomics institute that is famous for a series of high-profile breakthroughs in genomic sequencing, originally created the micropigs as models for human disease, by applying a gene-editing technique to a small breed of pig known as Bama. On 23 September, at the Shenzhen International Biotech Leaders Summit in China, BGI revealed that it would start selling the pigs as pets. The animals weigh about 15 kilograms when mature, or about the same as a medium-sized dog.
At the summit, the institute quoted a price tag of 10,000 yuan (US$1,600) for the micropigs, but that was just to “help us better evaluate the market”, says Yong Li, technical director of BGI’s animal-science platform. In future, customers will be offered pigs with different coat colours and patterns, which BGI says it can also set through gene editing.
With gene editing taking biology by storm, the field’s pioneers say that the application to pets was no big surprise. Some also caution against it. “It’s questionable whether we should impact the life, health and well-being of other animal species on this planet light-heartedly,” says geneticist Jens Boch at the Martin Luther University of Halle-Wittenberg in Germany. Boch helped to develop the gene-editing technique used to create the pigs, which uses enzymes known as TALENs (transcription activator-like effector nucleases) to disable certain genes.
How to regulate the various applications of gene-editing is an open question that scientists are already discussing with agencies across the world. BGI agrees on the need to regulate gene editing in pets as well as in the medical research applications that make up the core of its micropig activities. Any profits from the sale of pets will be invested in this research. “We plan to take orders from customers now and see what the scale of the demand is,” says Li. Continue Reading →

In 2012, when several hundred people fell ill in the U.S. amid a salmonella outbreak, the Food and Drug Administration was quickly able to isolate the exact strain of salmonella that had found its way into the contaminated sushi-grade tuna — and then trace it to the exact processing plant where the fish originated in India. (Not surprisingly, the FDA found 10 sanitation oversights, four of which were considered egregious.)
Then in 2014, the FDA managed to prevent a listeria outbreak from going beyond seven illnesses and one death when it traced the strain of the pathogen to soft cheeses manufactured by Ross Foods, which has since been shut down. Both findings are thanks to DNA sequencing, which is helping not only to identify which species of animals we might be eating, but even which strains of foodborne pathogens might be present in our food. The implications are broad. Knowing at a genetic level what we are eating isn’t just good for our health (think food allergies, high mercury levels, etc.) and for our wallets (how much are we really paying for tilapia?), but also for the animals (some of which are endangered or illegally hunted).

More than 300 delegates representing private and public sectors from 30 countries worldwide convened at the International Crops Research for the Semi-Arid Tropics (ICRISAT) global headquarters to deliberate on future collaborations and ways to integrate next-generation genomics into the future of crop improvement to contribute to global food and nutrition security. “Making a hunger- and malnutrition-free society is the ultimate goal of every agricultural scientist and stakeholder. Next-generation genomics backed by strong technological advancements will facilitate science-based agricultural innovations such as the development of nutrition-rich crops to eradicate hunger.”
This was according to Dr MS Swaminathan, renowned agricultural scientist and Father of India’s Green Revolution, at today’s successful conclusion of the three-day 5th International Conference on Next Generation Genomics and Integrated Breeding for Crop Improvement (NGGIBCI-V) held on 18-20 February 2015. Genomics – or deciphering the genomic content of crop species using high-throughput and next-generation approaches – allows the scientific community access to ‘good genes’ to speed up breeding for superior crop varieties with agronomically important traits. “It is not so much a question of more food.
