Drug-resistant genes spread through environment, not meat products.

New findings show that traffic from humans to animals, and back to humans via the environment,is responsible for resistant genes and as such a new focus on tackling antibiotic resistance is proposed. 

In the first study to track antibiotic resistance in intensively-farmed beef, scientists discovered a "startling" lack of resistance genes in meat. Meanwhile, in soil and feces samples from cattle pens they found genes resistant to a powerful "last resort" class of antibiotics called carpabemens that aren't used in the livestock industry.

These genes may have jumped from humans or companion animals to livestock, or could even be present at low levels in the wider environment.

 Results published in eLife suggest researchers and policy-makers need to switch focus to combat the growing problem of drug-resistant bugs. A current focus for policy-makers is to reduce antibiotic use in livestock to curb the spread of drug-resistant bugs.


The team urges that traffic from humans to animals, and back to humans via the environment, should be a new focus for research. The lack of resistance genes in post-slaughter meat samples was a big surprise for the scientists, forcing them to rethink the view that it is only antibiotic use that increases resistance.

 Environmental routes of exposure are much harder to trace and have been largely overlooked by researchers and policy-makers. While many people never step foot on working farms, we are physically connected to agriculture via waste water run-off and wind borne particulates.

 The scientists suggest investigating wind patterns and water flow to see if, and how, resistant bacteria may be disseminated, and how far.

 The researchers opined that they may observe that such dissemination is very limited geographically, or we may find that resistant bacteria can travel long distances if they find the right currents or the right waterways. In either case, this would be very important information from a public health perspective.

 The researchers collected samples from 1,741 commercial cattle. The study started in feedlots, where intensively farmed cattle are moved after grazing. A feedlot consists of outdoor pens where cattle are fattened during their final months of life.

 Samples were also taken during slaughter and from market-ready products. No previous studies have tracked antimicrobial use and resistance right through the beef production process.

The team found no resistance genes to any bacteria in market-ready beef products. They did discover changes to antibiotic resistance genes in the guts of cattle during their time in the feedlot. The changes could be due to the use of antibiotics in feedlots but could also result from adjusting to a high-energy diet or from the cattle's maturation from adolescent to adult.

How satellite technology is helping to fight illegal fishing.

A new initiative is arming coastguards with satellite intelligence that allows them to target their search for pirate fishing vessels in remote marine areas Pirate fishing vessels plundering fish from the world’s marine reserves, such as the one around Ascension Island announced on the weekend, can now be watched, tracked and brought to justice using satellite technology.Despite a proliferation of huge, publicly lauded marine reserves, actually stopping fishing in many remote areas has previously been almost impossible. Fishing vessels are required to carry a transponder that tracks their movements and allows authorities to monitor their behaviour. But illegal fishers simply switch off the machine, disappearing from the system. A UK-funded initiative, developed by Satellite Applications Catapult (SAC) and the Pew Charitable Trusts, uses satellite radars to track these “dark targets”. Now, instead of blindly patrolling vast areas of ocean, coastguard vessels use the satellite intelligence to target their search. Bradley Soule, senior fisheries analyst for SAC. Satellite radar has traditionally been used by the military and law enforcement agencies. But the cost has dropped dramatically, opening up the data for private companies to use.“It is definitely a big deal,” he said. “[The global satellite tracking] gives a sense of the scope ... It is a wide-ranging problem.” Roughly one in every five fish landed around the world is caught illegally.

TRACING WITH QR CODES TO PREVENT FOOD FRAUD.

The recalls concerning a lot of food items and pet products have sensitized the public about food sources,handling and codes.

The recalls are usually done per batches or dates of manufacture depending on where the error occurred, this has led to various means of tracing and tracking products that are fast,cheap and easy to use.   A company recently came up with an innovation using QR CODE

 A traceability system developed in New Zealand uses Quick Response (QR) codes so consumers with smartphones can have an easily accessible history of the source and status of an item, whether it happens to be a dairy product, a car, or any other merchandise.

 ID locate is a relatively new product developed by a company based in Auckland, NZ. Companies implementing the system pay a one-time setup charge and then a monthly maintenance fee, while consumers interested in their brands can use it for free.

 Woman scanning food with phone at storeSimon Bell, who handles technical and operational issues for the company, explained that the generated information can alert consumers to a food fraud problem, a related recall, or other issues involving a particular product.

 “It’s all database-driven so when they scan the QR code, it generates a particular URL so whatever information we have around that particular product is unique. It could be anything.

When a consumer scans it, it instantly tells them whether there’s a recall on that product,” “We’ve got a really good understanding of unique coding and imaging and a really good understanding of the application process.

 It’s incredibly secure and incredibly mobile; we can roll and do it in 15 minutes. We haven’t found anybody else who can do what we can do,” he said.

 There is almost no limit to the information which can be tracked on a food item. Besides the origin and recall history, it could be data from an outbreak investigation, video footage, or other content specific to that individual product,

 Bell noted. Lots of research is being done these days involving genetically engineered foods and various product investigations, but nothing has systematically been done linking that research with the consumer, he said.
