The presentation focused on research on mycotoxins as natural contaminants in the food chain. Some of the data on research carried out in the Food Research Laboratory on occurrence of aflatoxins in some food commodities including milk from local farms and foods imported from warmer regions of the world and marketed in the UK will be presented. Legislative levels of mycotoxins in food will also be considered. 

The presentation covered in vitro inhibitory effects of Fingerroot, a culinary herb, on formation of aflatoxin mutagenic metabolites. The Food Research Laboratory is accredited to ISO 17025 by the United Kingdom Accreditation Services (UKAS) and the consultancy includes services to food companies particularly in nutritional analysis, food pathogens, shelf life of foods and various aspects of food safety.

Molecular Aspects of Heat Stress Response of Rice Plants

Molecular Aspects of the Heat Stress Response of Rice Plants

by Prof Anil Grover - External examiner- Department of Plant Molecular Biology, University of Delhi South Campus Benito Juarez Road, DhaulaKuan, New Delhi‐110021, India (email:anil.anilgrover@gmail.com)

Rice (Oryzasativa L.) is the most important food crop. The rice transcriptional profile is significantly modulated by heat stress: the enrichment of GO terms protein kinase activity/ protein serine kinase activity, response to heat and reactive oxygen species in up‐regulated genes signifies the role of signal transduction events and reactive oxygen species during early heat stress (Mittal et al. 2012a,b, Sarkar et al. 2014). The proteins associated with chaperones and protein degradation machineries of the cell are stimulated as one of the early steps in minimizing damages to other proteins. Genome‐wide biology of rice Hsp20, Hsp40, Hsp70 and Hsp100 as well as heat shock factors has been unearthed from our studies (Sarkar et al. 2009, Singh et al. 2010, Sarkar et al. 2013a, Sarkar et al.2013b). Rice contains three ClpB/Hsp100 proteins localized to different cellular compartments: cytoplasm/nucleus (OsClpB‐c), mitochondria (OsClpB‐m) and chloroplast (OsClpB‐p) (Mishra and Grover 2015). OsClpB‐c (Os05g44340), OsClpB‐m (Os02g08490) and OsClpB‐p (Os03g31300) proteins are able to complement the thermo‐sensitive phenotype of yeast hsp100 mutant (ΔSchsp104) (Singh and Grover 2010, Singh et al. 2010). Arabidopsis Hot1‐3 is a null mutant for ClpB‐c gene, and is highly thermo‐sensitive both at the seed and seedling levels (Hong and Vierling 2000). We are interested to analyse the strategies of expression of Hsp100 forms which can possibly result into high temperature resistant crops. We have documented that OsHsfA2c (a) has rapid transcript induction under high temperature stress, (b) possesses transactivation activity, (c) forms homo‐oligomeric configuration, (d) regulates expression from OsClpB‐c promoter in heat shock element (HSE)‐dependent manner and (e) interacts with OsClpB‐c and OsHsfB4b proteins (Mittal et al. 2009, Mittal et al. 2011, Singh et al. 2012). We infer that supra‐complexes, involving several OsHsfs, regulate Hsp promoters under high temperature stress in rice.

Humble project management checklist by Dr John Mauremootoo



Projects of all kinds routinely fail to deliver on time, on budget and to specification; yet people continue to fall foul of ‘the planning fallacy’ – the tendency to underestimate the time, the costs, and the risks of future actions and at the same time overestimate the benefits of the same actions.
There are many explanations of why things rarely go according to plan. In this presentation I focus on irrationality and complexity; two important reasons why, in the words of former World Heavyweight Boxing Champion Mike Tyson, “Everybody has a plan, until he gets hit.”

I introduce some planning, monitoring and evaluation (PME) approaches as part of ‘a humble project
management checklist’ to guide us before, during, and after we get hit. I see these as ‘humble’ PME approaches because they serve to remind us that we need to understand and value the perspectives of
others so that we can see beyond our imperfect knowledge and perceptions.

Dr. Mauremootoo has over 30 years of experience in project planning, implementation,
monitoring, and evaluation. In his own words “Through sweet and bitter experience, long discussions and a lot of reading and reflection, I am continually learning what distinguishes effective and ineffective projects. This experience is the raw material for the humble project management checklist.”
He gave a talk on 11 June 2015 at the LT2 of the New Academic Complex of the University of Mauritius

Talk on Humble plants that hide surprising secrets by Prof Ameenah Gurib Fakim

In this intriguing talk, biologist Ameenah Gurib-Fakim introduces us to rare plant species from isolated islands and regions of Africa. Meet the shape-shifting benjoin; the baume de l'ile plate, which might offer a new treatment for asthma; and the iconic baobab tree, which could hold the key to the future of food. Plus: monkey apples.

Are HoneyBees dying en masse?



Honeybees have thrived for 50 million years, each colony 40 to 50,000 individuals coordinated in amazing harmony. So why, seven years ago, did colonies start dying en masse? Marla Spivak reveals four reasons which are interacting with tragic consequences. This is not simply a problem because bees pollinate a third of the world’s crops. Could this incredible species be holding up a mirror for us?

World Environment Day 2015


 





 This Friday, June 5, is World Environment Day (WED) which celebrates positive environmental action and calls on each of us to create change. The theme of WED—“Seven Billion Dreams. One Planet. Consume with Care”—reminds us that we only have one planet, and that the Earth’s natural resources are finite, not unlimited.

SHARE this with your social network!

According to the United Nations Environment Program, if current consumption and production patterns remain the same with a rising population, by 2050, we will need three planets to sustain our way of living and consuming.
Food production is a major culprit in the consumption of natural resources, accounting for 10 percent of the energy consumed in the United States, 80 percent of freshwater consumed, and 50 percent of land usage.
Sustainable America’s “I Value Food” campaign highlights the numbers involved in food waste. In fact, according to I Value Food, American consumers spend US$371 per person per year on food that gets wasted; on average, food travels 1,500 miles from farm to table. Twenty-six percent of meat products end up in landfills, which adds up to more than 47 billion wasted calories—or enough to feed 8,600 children for a year.
U.N. secretary-general Ban Ki-moon says, "Although individual decisions may seem small in the face of global threats and trends, when billions of people join forces in common purpose, we can make a tremendous difference."
This WED—and every day—we can all take steps to minimize food-related resource consumption. Here are a few ways to consume food more responsibly:

SHARE this list and use #WED2015!
Waste not, want not: In the United States, 40 percent of edible food is wasted. Throwing away good food wastes natural resources. There are many simple things eaters can do to reduce household food waste. Plan meals and inventory your refrigerator and freezer before heading to the store. Buy only what you need and will realistically use. Repurpose leftovers and food scraps. Portion carefully. Freeze or preserve excess food before it goes bad. Donate good food to food banks before throwing it away. Last but not least, compost what you can’t use in any other way.
If you want to get more involved in reducing food waste, here are some organizations doing important work on that issue:
  • Andrea Segrè, president of the Last Minute Market (LMM), analyzes steps in the food chain to see where waste originates. LMM recovers and reuses unsold good from mass retailers.
  • In Berlin, Culinary Misfits repurposes ugly produce for use in catering.
  • DC Central Kitchen has recovered hundreds of thousands of pounds of food which they use to feed those in need.
  • Feedback works to end global food waste at every level of the food system through awareness events and repurposing campaigns.
  • Food Recovery Network creates food recovery programs on college campuses across the country to salvage food that would otherwise be thrown away.
  • The Food Waste Reduction Alliance aims to keep food out of landfills and increase distribution of food to those in need.
  • FUSIONS tries to reduce Europe’s natural resource consumption by decreasing food waste.
  • Jonathan Bloom has been researching and writing about food waste since 2005 and his blog, Wasted Food, draws attention to how consumers can cut their waste.
  • Love Food Hate Waste is educating consumers in the United Kingdom about food waste.
  • Society of Saint Andrew salvages food from America’s farms and delivers it to food pantries.
  • Danish food waste expert Selina Juul founded the Stop Wasting Food movement in Denmark which has gathered thousands of followers as well as support from over 90 politicians, including members of parliament in Denmark and across Europe.
  • Think.Eat.Save seeks to raise awareness of and galvanize global action on food waste.
Buy organic when you can. There are more benefits to organic than simply avoiding toxins. Organic agriculture is inherently low-input, involving fewer natural resources, and embraces closed-loop systems that recycle those resources that are used. The U.S. Department of Agriculture organic standards include sustainability requirements, ensuring that organic producers are preserving natural resources and protecting biodiversity.
Choose foods with less packaging, or bring your own. Buy fresh, whole foods, and buy in bulk when possible. If buying in bulk, bring your own container or bag. Skip the produce bag or bring a reused one from home. If your grocery store offers it, buy milk in a glass bottle from a company that will reuse it.
Eat fewer industrial meat products. Michael Pollan put it best: “Eat food. Not too much. Mostly plants.” Industrial meat production consumes vastly more natural resources than plant-based agriculture. According to the Water Footprint Network, one pound of beef requires almost two thousand gallons of water. Even the federal nutrition panel emphasized choosing a plant-based diet for a sustainable food system in their new nutrition guideline recommendations. If you are going to consume animal products, buy from your local farmer, and buy grass-fed and pasture-raised. Go vegan one day a week or one meal a day.
Grow your own. On a patio, in a window box, in your kitchen, in your backyard, in a community garden; every little bit counts. You’ll reduce your food miles, avoid the unsustainable practices of industrial food production, and learn to value your food more.
If you do grow your own food, plant drought-tolerant crops, water in the evening, or use an irrigation system to save water. If you don’t, encourage your farmer to use these practices.
Encourage policymakers to support sustainable agriculture. Vote for representatives (and then write to them!) locally and nationally who support sustainable agriculture legislation and programs, and who are willing to stop subsidizing overproduction, unsustainable practices, and waste in our agriculture system. Organizations such as Food Policy Action are changing the national dialogue by holding legislators accountable for how they vote on policy that affects food and farming.
Make responsible, conscientious food choices. Not all food is created equal. Some products are less sustainable than others. Check how far your food has traveled, and choose items that journeyed a shorter distance, such as fruits from Florida or California instead of South America or Asia. When buying seafood, choose those items that are most eco-friendly, such as wild-caught Alaskan salmon, sardines, or Chesapeake Bay catfish—products that don’t devastate the ecosystems from which they are harvested.

What other ways are you consuming food more responsibly? We want to know! Share them with me at Danielle@foodtank.com and on social media with #WED2015!

All the best,

Animal Biodiversity

«The diversity of livestock and crop variety can be considered a dictionary of sorts, thanks to which it is possible to adequately answer the needs of the great diversity of territories…».
Wendell Berry

Two sets of opposing photographs: a striking number of Friesian cattle on an intensive farm, distributed in circles around milking machines, contrasts with the image of Grigio Alpina cattle grazing on pastures; a Texan feedlot in which hundreds, if not thousands of beef cattle are confined, and Limpurger cows, once again grazing fields, with different spaces and types of feed available. And many more images, videos, as well as a booklet on Animal Biodiversity, demonstrating that among the different themes explored by Slow Food at Expo, animal welfare and animal biodiversity could certainly not go amiss.

Ph. Terry Mathews/Alamy, the milking phase on an intensive milk farm, United Kindom.
The booklet traces the history of the relationship between human beings and animals, a history with very ancient roots. Dogs were the first animals to be domesticated around 15,000 years ago; followed by sheep and goats, due to their size and frugal nature, and finally cattle. The first breeders chose species that would easily reproduce in captivity, have a fast growth rate, large litters and short intervals between births. They chose animals that were less aggressive, instinctively gregarious and privileging herbivorous species as they were easier to feed.
Only few species possessed all these characteristics, in fact out of over 50,000 known wild animal species, only 40 were domesticated, with only 18 of these being mammals. Thousands of different breeds originated from these 40 species, thanks to their adaptability to different environmental conditions and man-made selection, which has always been aimed at developing the most useful characteristics through specific cross-breeding.
Animal breeds are identified on the basis of physical characteristics (size, color of fur or plumage, shape of the head, limbs, horns and tail) and abilities (productivity, in terms of eggs, milk and meat, resistance to cold temperatures, ability to graze in difficult pastures, prolificity, etc.) that adults transmit to their offspring. Breeds are defined as native or local when their characteristics are tied to the climate, geographical and social-economic condition of the area in which they have developed or adapted to over time. Local breeds are able to live in extreme environments, as they require less attention and food, as is the case for the Villsau Sheep, an ancient breed that lives along the icy northern Norwegian coast, on rocky terrain and very poor pastures.
