Microchip and RFID Summary: In 2014, a microchip is the size of a grain of rice. They are easily implanted into a horse using a simple syringe. The microchip is implanted in the nuchal ligament on the left side of the neck. They are so small, the only way to detect if horse has a microchip is to use a scanner.
Each microchip contains a unique number that cannot be altered or deleted. A microchip implanted in a horse is of little value. However when connected to a related database, the unique number can be used to connect with records that contain information the horse.
Can any scanner read any chip? Although compatibility was an issue when animal microchipping was first introduced in the 1990s, the International Standard Organization (ISO) imposed global standard for microchips to remove the incompatibility issues so that any ISO microchip can be read by any universal scanner (regardless of the manufacturer). Therefore, to read a microchip implanted in a horse all you need is an ISO standard microchip and a Universal Scanner. These scanners are readily available online for between $200-300. Most veterinarians and animal control officers carry universal scanners.
What are the differences between Cat, Dogs and Horses? The microchips that are implanted in horses are the same microchips that are implanted in cats and dogs. However, the difference lies in the registries. As previously noted, a microchip has no value without a registry or database to house information related to each microchip. There is a number of cat and dog registries, but only two registries designed for horses.
The cat and dog registries are numerous; Petlink, Home Again, Petkey are some examples. These registries will take horses, but there is no value in registering a horse in these registries because they are not designed, nor are they used for horses. .
Are there Registries for horses? The Equine Protection Registry offered by MicrochipIDSystems is designed exclusively for horses. Therefore it is ERN’s choose of a registry for horses.
How can Microchips benefit Horses? Until recently, there has been very little reason to microchip horses. Unlike cats and dogs, they typically don’t run away from home so why microchip a horse? However, there has been an increasing awareness to Microchipping in the horse community, and a number of entities that now require microchipping.
Benefits for All Horses: There are 9.2 million horses in the USA. Keeping track of those 9.2 million horses is becoming increasingly difficult using traditional measures of unique markings and naming conventions. There is no mistaken identity with Microchips. Unlike brands and tattoos, Microchips cannot be altered, deleted or removed without notable scaring and damage. Microchipping is an asset to many breeds with common appearances, like Fresians where one Fresian gelding looks identical to the next Fresian gelding. Microchips make identification simple, fast and accurate. Additional benefits are noted below:
• Permanent ID that cannot be separated from the animal
• Not removable ~ Not alterable (Read Only Technology)
• Proof of ownership
• Helps provide theft protection and aids in recovery of stolen horses
• Disaster recovery
• Access to online health certificates
• Medical records
• Farm management
• Accuracy at Competitions and Equine Events
• Required for most travel documentation (Example: Microchip is required for International Horse Passport)
• Identification for sales documentation
• Integrity of show and pedigree records
• Can be implanted in foals just after birth
• Easy to administer
• Study shows less trauma to the horse
• Slaughter horse management
• There is a national HOTLINE for available for microchipped horses: 24/7/365 for animal control and crisis management
Benefits for Unwanted Horses: The Equine Rescue Network has implemented a growing nationwide network of individuals and volunteer who now scan horses at auctions and killpens. If a slaughter-bound horse is found with a microchip or tattoo, they are able to notify previous owners. No one wants to get a call that a previously owned horse is about to ship to Canada or Mexico for slaughter. Yet ERN has found that 85% of the time, the previous owners welcomes the call and are happy to help, even if means to humanely euthanize the horse.
Who is Microchipping? Below are just a few examples of organizations and governments that currently require microchipping:
• The FEI requires microchipping
• Oldenburg Horse Breeders Society requires microchipping
• United Kingdom, Horse Passports require Microchipping as of 2009
• Microchip is required for horses entering Canada from European Union Member States
• 2014/15 Equestrian Australia states – All Horses must be microchipped (Compulsory from 1st July 2008) according to the Australian Standard AS 5018/5019
• A result of the 2006 National Animal Disaster Summit determined that all animals rescued during a disaster will be implanted with microchips
• January 2008 it has been a legal requirement in France for all equines to be microchipped
• DSPCA (Dublin, Ireland) 2009 Passport requires Microchip for equines
• Louisiana Department of Agriculture and Forestry (LDAF) issued a regulation requiring permanent identification (in the form of a brand, lip tattoo or electronic identification)
• Dutch Warmblood horses are no longer branded, instead all horses are required to have a microchip
• …..AND there are many more…..
Adverse effects of Microchipping (the why not!) Many animal and horse owners are reluctant to microchip given the propaganda over the Internet related to animal welfare and microchips. The American Veterinary Medical Association supports microchipping for animal welfare. The American Association of Equine Practitioners also recommends microchipping as a means to identify horses and protect horses during national disasters.
The American Veterinary Medical Association is a valuable source of information regarding the adverse effects of microchips. They note:
“British Small Animal Veterinary Association (BSAVA) maintains a database of adverse reactions to microchips. Since the database was started in 1996, over 4 million animals have been microchipped and only 391 adverse reactions have been reported. Of these reactions, migration of the microchip from its original implantation site is the most common problem reported. Other problems, such as failure of the microchip, hair loss, infection, swelling, and tumor formation, were reported in much lower numbers.”
Microchip Migration: The veterinary association and scholarly articles have tested the migration of microchips and have reported no evidence that support migration of microchips. See Stien, Geller, Carter (2003).
Unreadable chips: Microchips are implanted in the nuchal ligament on the left side of the neck. It is extremely, extremely rare that a microchip will fail, most readability issues are with the scanner. However, this problem has been solved by the International Standard Organization (ISO) who set global standard for microchips so that all ISO microchips can be read by any universal scanners (at 134.2-kHz frequency).
Microchips Cause Cancer and tumors: The issue of tumor and cancer has surfaced and re-surfaced over the years. The scholarly literature and veterinary associations explain there is little direct evidence that support the relationship between cancers, tumors and microchips. Given there are 15 million of animals who now have microchip implants, if there is a correlation, it is not statistically significant enough to cause concern.
The AVMA report:
“There have been reports that mice and rats developed cancer associated with implanted microchips. However, the majority of these mice and rats were being used for cancer studies when the tumors were found, and the rat and mice strains used in the studies are known to be more likely to develop cancer. Tumors associated with microchips in two dogs and two cats have been reported, but in at least one dog and one cat the tumor could not be directly linked to the microchip itself (and may have been caused by something else).”
