Keeping track of problems

Nobody asked for electricity when it was invented. Thanks to marketing and powerful lobbying, electricity is now something both businesses and consumers can’t do without.

Not all technological innovations have been that lucky, though.

Radio-frequency identification, or RFID, has been trying to make an inroad into animal health for quite some time.

While it has succeeded in penetrating the retail sector, via supermarkets and to a certain extent, pharmaceuticals, it still has to justify its existence to agricultural groups and packaging sectors that are still comfortable with low-tech identification (ID) techniques, such as barcode labelling.

Digital Angel’s announcement to restructure its Destron Fearing animal ID business shortly after receiving approval from the US Department of Agriculture (USDA) for its swine livestock identification tag system does not come as a shock, given the current financial climate in the US and the various issues plaguing animal ID and RFID in general.

As you would know, the European Union (EU) requires all sheep and goats across the European Union to be electronically tagged by the end of 2010 (Regulation 21/2004). Tagging the animals will not stop the disease. What it can do is to help the relevant authorities to monitor the movement of livestock through the supply chain, and hopefully identifies the source of an outbreak when the proverbial hits the fan.

The proverbial finally hit the fan this month. A small bluetongue outbreak occured in the southeast of Germany. A few days after this incident, which took place in the Ortenaukreis district, near the French border, the disease was identified in Portugal. Spain is monitoring the situation closely.

In January this year, Spain and Italy made their unhappiness clear when the mandatory tagging of livestock was postponed from the end of 2009 to the end of 2010 (EU extends electronic ID deadline for sheep and goats to January 2010, 8th January 2008). Despite the technical and financial obstacles, Spain and Italy committed a significant amount of resources at national level to prepare for the 2009 deadline.

They found the excuses put forward by other member states who ‘failed’ to meet the deadline simply “unacceptable”.

The UK, egged on by the sheep industry, welcomed the postponement.

I suppose the Southern Europeans have a valid reason in supporting an automated animal monitoring process. The geography makes the spread of the unwanted – and I am not just talking about animal diseases – a tad easier in the region than in an isolated island like the British Isle. Meat products are a major revenue earner for Spain and Italy, so they can’t afford to mess up.

The story, however, is slightly different in the UK, where living and operating costs are ridiculously high. An animal tagging system integrator told me that the resistance against the 21/2004 regulation “is being led by the sheep industry in its fight against double-tagging”.

“Double-tagging” is a peculiar issue, and it doesn’t help the RFID cause one bit. The 21/2004 directive requires all sheep to be double-tagged in any event when leaving holding of birth. From January 2008, one of the tags must be an electronic device. Individual recording of livestock will also be compulsory.

Again, if you have hundreds of sheep, you have little choice but to do this electronically. Setting up a new electronic record-keeping system costs money. To muddle matters further, the 21/2004 directive gives a further derogation that “lambs” (yes, baby sheep) leaving their holding of birth do not require an electronic device.

Before you come to the conclusion that lamb-tagging is daft, I'll have you know that the UK's Institute of Animal Health (IAH) thinks bluetongue virus can be passed by pregnant ruminants to the foetuses they carry. IAH reckons that's how it survives the winter (Bluetongue virus might survive the winter within foetuses, 5th March 2008).

The same chap told me that the beef industry, very much spooked by bovine spongiform encephalopathy (BSE), supports electronic tagging. It’s the sheep farmers that are throwing the spanners in the works.

So how much does an average tagging system cost then, I asked.

“A handheld reader starts from £60. A slaughter line is from about £2500, and a livestock market system with multireaders, £10,000. Tags are priced from £0.16 to £0.85 per piece.”

(No) thanks to global warming, midges can survive the Northern European winter and spread the disease all year round. Isn't it time the animal health industry stops compensating for other industries' greenhouse activities, and do something to reduce carbon emission in agriculture? Photo: Institute of Animal Health

If it’s true that the basic cost of the EU scheme to the UK farmer would be between £13,000 and £16,000 – according to DEFRA – and if it’s true that the average UK farmer is earning below £15,000 a year, then both the sheep industry and the animal tagging industry can kiss each other goodbye. With about 67 million sheep movements a year, how could the sheep farmers cope with the costs? And let’s not forget the rising feed costs.

Animal tagging is a novel idea, one that I support wholeheartedly. But like many types of technology, it needs to be supported by a justifiable business strategy. The much-touted Wireless Application Protocol (WAP) has been around for more than 10 years, but hey, if you can organise a knees-up with good old text messaging, why need WAP? Similarly, if you can get by with good old head-counting and low-tech ID methods, why bother upgrading?

But if we have a reliable tracking and tracing system in place, it will be a lot easier to know where to look first when the diseases strike again.
