Domestic chicken keeping needs more regulation to protect human and animal health

Colorado has received a lot of attention recently as one of the first states to allow recreational marijuana, but it’s also legalising other things. Denver, one of the USA’s hottest urban real estate markets, is surrounded by municipalities that allow backyard chicken flocks.

This isn’t just happening in Colorado. Backyard chickens are cropping up everywhere. Nearly 1 per cent of all U.S. households surveyed by the U.S. Department of Agriculture reported owning backyard fowl in 2013, and 4 per cent more planned to start in the next five years. That’s over 13, Americans flocking to the backyard poultry scene. Ownership is spread evenly between rural, urban and suburban households and is similar across racial and ethnic groups. A 2015 review of 150 of the most-populated U.S. cities found that nearly all (93 per cent) allowed backyard poultry flocks.

Our lab group analyses health issues that connect humans, animals and the environment. In a recent study with University of California, Davis animal scientist Joy Mench, we examined urban poultry regulations in Colorado – the only state that collects and makes public animal shelter surrender data. Our findings suggest that, as backyard chicken farming spreads, states need to develop regulations to better protect animal welfare and human health.

When animals roamed the streets

U.S. cities once were powered by animals. Horses provided transport through the early 1900s. Pigs and hens fed on household garbage before municipal trash collection became routine. Thousands of cattle were driven up Fifth Avenue in New York City daily in the late 19th century, occasionally trampling children and pedestrians.

To reduce accidents, disease and nuisances, such as piles of smelly manure and dead animals, early public health and planning agencies wrote the first ordinances banning urban livestock. By the 1920s, farm animals and related facilities such as dairies, piggeries and slaughterhouses were barred from most U.S. cities. Exceptions were made during World War I and World War II, when meat was rationed, encouraging city dwellers to raise backyard birds.

Locavores and animal lovers

The local food movement has helped drive interest in raising backyard birds. People want to grow their own food. In response, cities across the country are modifying regulations and overturning long-standing bans to legally accommodate backyard chickens.

Surveys show that backyard chicken owners are concerned about where their food comes from, how it was produced and possible risks associated with eating industrially produced meat and eggs. They believe their birds have a better quality of life and produce safer and more nutritious eggs and meat than commercially raised versions.

Risks to humans and chickens

However, raising backyard chickens is not risk-free. As one example, an outbreak of highly infectious H5N1 avian influenza in Egypt resulted in 183 confirmed cases and 56 deaths between 2014 and 2016. The majority of clinically confirmed cases were linked to close contact with diseased backyard birds.

In the United States, contact with backyard poultry is associated with hundreds of multistate salmonella outbreaks every year. A 2016 USDA survey of backyard poultry owners found that 25 per cent of respondents did not wash their hands after handling birds or eggs. In another study, the majority of backyard owners knew little about identifying or preventing poultry diseases.

Commercial poultry facilities protect birds against a variety of diseases by injecting vaccines into growing chicks while they are still in the egg. Many backyard growers do not know to request vaccinated birds when they purchase chicks or eggs. In 2002 an outbreak of exotic Newcastle disease in California originated in backyard flocks and spread into commercial poultry operations. Operators had to euthanize more than 3m birds. They received compensation from USDA for doing so, which cost taxpayers US$161m. USDA also had to restrict poultry exports, which caused economic losses for commercial poultry producers.

Many animal control and welfare agencies around the country oppose allowing urban livestock. Some activists argue that it can foster abuse, inhumane conditions and the development of backyard “factory farms,” and increase burdens on thinly stretched animal shelters and rescue groups.


Few rules for backyard flocks

We began our study by reviewing every local law in the state of Colorado pertaining to livestock. Then we looked at Colorado animal shelter and rescue data for 2014 and 2015. We wanted to see whether counties with large commercial operations were likely to prohibit raising backyard birds; when most ordinances originated; and what animal care standards were written into local laws.

We found that 61 of 78 Colorado municipalities allowed backyard chickens, and only 13 municipalities explicitly banned the practice. Local laws most commonly controlled for coop design and placement, prohibited owning roosters and limited the total number of birds allowed. Unlike commercial guidelines or typical standards for domestic cats and dogs, most ordinances did not require vaccination or veterinary care.

Very few regulations required humane slaughter or disease reporting. Only four municipalities required owners to provide birds with food; 16 required water, and two mandated veterinary care as warranted. Many owners understand that water and food are basic necessities, but when cities do not codify these requirements, animals have little legal protection and are not officially entitled to veterinary care even when they are sick, injured or dying.

On the positive side, we found that most shelters had not yet experienced an increase in chicken intake, and reported that people were interested in taking in stray chickens. But several organisations were concerned that they would receive more chickens in the future as the number of homes with space for stray birds decreased.

Setting higher standards

We found several cities with model ordinances that safeguarded avian and human health. Fort Collins, home to Colorado State University’s College of Veterinary Medicine, requires annual permitting fees that are collected by the nonprofit Larimer Humane Society. The agency educates owners about disease prevention and husbandry and connects them with veterinarians and agricultural extension agents.

Nonprofit animal welfare agencies often depend heavily on donations to run animal shelters and care for strays. Fee systems such as that required in Fort Collins can help them cover costs of managing unwanted and stray animals. And streamlined permitting overseen by animal welfare agencies and veterinarians can prevent many backyard diseases or catch them early.

The ConversationBased on our survey of Colorado, we believe cities need to carefully consider their backyard chicken regulations and develop strong legal frameworks that protect animal and human health and welfare. In particular, they should develop rules that require food and water, mandate veterinary care and connect owners with animal welfare agencies.

Uber has introduced a levy to fund electric vehicles in London. But who exactly is benefiting?

Uber is introducing a levy of 15p per mile on London users to help fund a transition to electric vehicles and help tackle air pollution. Its goal is to encourage half its drivers to go electric by 2021 and to go fully electric by 2025.

There are a number of benefits to the idea. Moving to cleaner transportation is an important public good with a myriad of general health benefits. It should be an urgent priority for all UK cities. But the question of who pays for this transition is fundamental to whether it is done fairly. As a process, change needs be done in partnership with people, not to them.

So who is actually being asked to foot the bill for this much needed transition? Fresh analysis by the New Economics Foundation shows that while the PR benefits are likely to accrue to Uber, its consumers and drivers will foot the bill in its entirety, while also taking on much of the risk.

Uber estimate that drivers will be eligible for £4,500 in funds to purchase a new electric vehicle after three years of service – the maximum period of time for which drivers can accrue credit. By comparison, the cost of a cheap second-hand electric car meeting Uber’s requirements for UberX costs in excess of £12,000, while a second hand vehicle suitable for UberLux would set drivers back around £45,000.

For those drivers receiving around £4,500, this would still imply the need to contribute thousands of pounds, if not tens of thousands, in personal funds. Even after allowing for a fall in prices for electric vehicles, drivers are being asked to make a minimum contribution of between 55 per cent and 85 per cent towards the total cost of electrification. The remainder of the cost will be met indirectly by consumers – either in the form of higher charges or else being priced out Uber’s services altogether.


Where drivers don’t have access to this sort of cash, the expectation will be that they borrow – which means taking on the risk of debt repayments while earning close to minimum wage. Being able to keep the 15p levy once driving an electric vehicle is unlikely to cover the cost of new interest payments. But failure to use the scheme at all could mean unemployment after 2025.

While drivers are forced into arrears to consolidate their jobs, Uber may also find itself with a considerable surplus from the scheme, as a result of drivers leaving the platform early or choosing not to apply for the grant. Uber has suggested that any surplus will be reinvested into supporting facilities, such as charge points for electric cars. But this means that the cost of moving to green infrastructure is coming at the expense of extra private debt for drivers (which could otherwise have been funded out of the levy). Such a trade-off is simply incompatible with a green transition that is morally just.

The shift in strategy from Uber towards more renewable transport technology is clearly welcome on environmental grounds. Doing so solely at the expense of consumers drivers is not. For any transition to be fair, Uber needs to meet its share of the costs.
