An agricultural show is a public event exhibiting the equipment, animals, sports and recreation associated with agriculture and animal husbandry. The largest comprise a livestock show (a judged event or display in which breeding stock is exhibited), a trade fair, competitions, and entertainment. The work and practices of farmers, animal fanciers, cowboys, and zoologists may be displayed. The terms agricultural show and livestock show are synonymous with the North American terms county fair and state fair .
The first known agricultural show was held by Salford Agricultural Society, Lancashire, in 1768. [1]
Since the 19th century, agricultural shows have provided local people with an opportunity to celebrate achievements and enjoy a break from day-to-day routine. [2] With a combination of serious competition and light entertainment, annual shows acknowledged and rewarded the hard work and skill of primary producers and provided a venue for rural families to socialise. City shows also provide city people with an opportunity to engage directly with rural life and food production. [3]
Agriculture shows are often enlivened with competitive events, including sheaf tossing, show jumping, food competitions, and tent pegging. Demolition derbies and rodeos are popular in the US and campdrafting and wood chopping are often held in Australia.
Studs are generally available for a fee.
A livestock show is an event where livestock are exhibited and judged on certain phenotypical breed traits as specified by their respective breed standard. Species of livestock that may be shown include pigs, cattle, sheep, goats, horses, rabbits, llamas, and alpacas. [4] Poultry such as chickens, geese, ducks, turkeys, and pigeons are also shown competitively. [5] There are also competitive shows for dogs, sheepdogs, and cats.
Prize-winners at agricultural shows are generally awarded inscribed medals, cups, rosettes or ribbons. The National Museum of Australia has a rare collection of medals documenting the history of agricultural shows and rural industries across Australia. [3] The 111 medals range in date from the mid-19th to the early 20th century and many are associated with significant individuals and organizations. [6]
Related to a show is the "field day", with elements of a trade show for machinery, equipment and skills required for broadacre farming. Field days typically do not involve livestock, show bags or sideshows, but may include events such as ploughing competitions not usually associated with shows due to the larger space required. In some communities in northern England Field Days (or Club Days) have lost their agricultural character and have become community celebrations.
The events are good sources of agricultural information, as organizers can arrange for guest speakers to talk on a range of topics, such as the talk on the yellow-flowering alfalfa at the South Dakota field day. [7] Pecan growers were given a talk on insect control by an entomologist at a recent field day at LSU AgCenter's Pecan Research/Extension Station in Shreveport, La. [8]
A Landcare survey conducted in 1992/93 revealed that field days in Australia have a high value among local farmers. [9] New Zealand's National Agricultural Fieldays is held annually in June at Mystery Creek, near Hamilton, New Zealand, and attracts 1,000 exhibitors and over 115,000 visitors through its gates. [10] Smaller shows, held annually in New Zealand's towns and communities, are generally called agricultural and pastoral shows (A&P shows).
Agricultural shows can be sources of swine influenza transmission in both animal and human populations. Swine influenza is a communicable disease caused by one of several different strains of influenza A virus. Currently, the subtypes of influenza A virus which have been identified in pig populations within the United States are referred to as H1N1, H1N2, and H3N2, all named for their specific genetic makeups. [11] These viruses are extremely common in pigs across various industries, including pig showmanship at agricultural fairs, and are easily passed between pigs when proper hygiene and safety measures are not carried out.
It is rare for the virus to spread to humans; however, genetic reassortment can lead to susceptibility among humans. [12] Due to direct contact with infected animals or a contaminated environment, swine influenza strains can be transmitted to human populations. [13] In cases such as the 2009 flu pandemic, the virus was transmitted from swine to humans and caused a global pandemic which led to the deaths of approximately 12,000 people in the United States alone. [14] For this reason, people who work or spend any time in close proximity with pigs are at risk for infection and must follow specific precautions to prevent the spread of swine influenza.
Certain populations at agricultural fairs are at increased risk of developing serious complications after swine influenza exposure. For instance, pregnant women are more susceptible to swine influenza and have been shown to have increased rates of swine influenza mortality relative to the general population. [15] Similarly, adolescents, infants, and those with serious medical comorbid conditions have disproportionately high rates of mortality with swine influenza. [16] This is concerning as over 3.5 million children in the United States participate in youth agricultural programs every year. [17]
Agricultural fairs can readily lead to swine influenza infection in vulnerable populations because agricultural fairs are frequently visited by entire families, including children and pregnant women. [18]
Swine influenza variant viruses have been responsible for several recent outbreaks in the United States associated with contact with pigs at agricultural fairs. The three main Influenza A viruses responsible for these outbreaks are variants of the Influenza A viruses H1N1, H1N2, and H3N2.
Recent swine influenza variant outbreaks associated with agriculture fairs in the United States:
In the United States, agricultural fairs are a significant exposure source for swine influenza. [23] Certain strains of swine influenza can be transmitted from pig to pig, pig to human, and human to human; swine influenza infection does not always show signs of illness. [24]
There are a variety of safety precautions that should be taken at agricultural fairs to prevent the spread of swine influenza. Vulnerable communities including children, people aged 65 years and older, pregnant women, and those suffering from long-term health conditions are groups who should avoid swine exposure due to their high-risk status. [25] The CDC specifically recommends that high-risk individuals with known medical complications avoid interaction with swine at agricultural fairs. [26] It is advised that anyone who develops flu symptoms after swine exposure at agricultural fairs contact their physician for appropriate medical consultation.
There are other recommended prevention strategies to reduce the spread of swine influenza at agricultural fairs. It is suggested that people do not bring food into pig areas, do not take any items such as toys, pacifiers or similar items near the pig areas, avoid close contact with any pigs, and wash hands before and after handling pigs. [27] Given the severity of the disease, it is prudent to adopt safety precautions to limit the spread of the swine flu.

Influenza A virus (IAV) is a pathogen that causes the flu in birds and some mammals, including humans. It is an RNA virus whose subtypes have been isolated from wild birds. Occasionally, it is transmitted from wild to domestic birds, and this may cause severe disease, outbreaks, or human influenza pandemics.
Antigenic shift is the process by which two or more different strains of a virus, or strains of two or more different viruses, combine to form a new subtype having a mixture of the surface antigens of the two or more original strains. The term is often applied specifically to influenza, as that is the best-known example, but the process is also known to occur with other viruses, such as visna virus in sheep. Antigenic shift is a specific case of reassortment or viral shift that confers a phenotypic change.
The Hong Kong flu, also known as the 1968 flu pandemic, was a flu pandemic that occurred in 1968 and 1969 and which killed between one and four million people globally. It is among the deadliest pandemics in history, and was caused by an H3N2 strain of the influenza A virus. The virus was descended from H2N2 through antigenic shift, a genetic process in which genes from multiple subtypes are reassorted to form a new virus.
Swine influenza is an infection caused by any of several types of swine influenza viruses. Swine influenza virus (SIV) or swine-origin influenza virus (S-OIV) refers to any strain of the influenza family of viruses that is endemic in pigs. As of 2009, identified SIV strains include influenza C and the subtypes of influenza A known as H1N1, H1N2, H2N1, H3N1, H3N2, and H2N3.
Flu season is an annually recurring time period characterized by the prevalence of an outbreak of influenza (flu). The season occurs during the cold half of the year in each hemisphere. It takes approximately two days to show symptoms. Influenza activity can sometimes be predicted and even tracked geographically. While the beginning of major flu activity in each season varies by location, in any specific location these minor epidemics usually take about three weeks to reach its pinnacle, and another three weeks to significantly diminish.
In virology, influenza A virus subtype H1N1 (A/H1N1) is a subtype of influenza A virus. Major outbreaks of H1N1 strains in humans include the 1918 Spanish flu pandemic, the 1977 Russian flu pandemic and the 2009 swine flu pandemic. It is an orthomyxovirus that contains the glycoproteins hemagglutinin (H) and neuraminidase (N), antigens whose subtypes are used to classify the strains of the virus as H1N1, H1N2 etc. Hemagglutinin causes red blood cells to clump together and binds the virus to the infected cell. Neuraminidase is a type of glycoside hydrolase enzyme which helps to move the virus particles through the infected cell and assist in budding from the host cells.
An influenza pandemic is an epidemic of an influenza virus that spreads across a large region and infects a large proportion of the population. There have been six major influenza epidemics in the last 140 years, with the 1918 flu pandemic being the most severe; this is estimated to have been responsible for the deaths of 50–100 million people. The 2009 swine flu pandemic resulted in under 300,000 deaths and is considered relatively mild. These pandemics occur irregularly.
Influenza A virus subtype H3N2 (A/H3N2) is a subtype of viruses that causes influenza (flu). H3N2 viruses can infect birds and mammals. In birds, humans, and pigs, the virus has mutated into many strains. In years in which H3N2 is the predominant strain, there are more hospitalizations.
Canine influenza is influenza occurring in canine animals. Canine influenza is caused by varieties of influenzavirus A, such as equine influenza virus H3N8, which was discovered to cause disease in canines in 2004. Because of the lack of previous exposure to this virus, dogs have no natural immunity to it. Therefore, the disease is rapidly transmitted between individual dogs. Canine influenza may be endemic in some regional dog populations of the United States. It is a disease with a high morbidity but a low incidence of death.
Influenza A virus subtype H1N2 (A/H1N2) is a subtype of the species Influenza A virus. It is currently endemic in pig populations and is occasionally seen in humans.
Fujian flu refers to flu caused by either a Fujian human flu strain of the H3N2 subtype of the Influenza A virus or a Fujian bird flu strain of the H5N1 subtype of the Influenza A virus. These strains are named after Fujian, a coastal province in Southeast China.
Influenza, commonly known as "the flu" or just "flu", is an infectious disease caused by influenza viruses. Symptoms range from mild to severe and often include fever, runny nose, sore throat, muscle pain, headache, coughing, and fatigue. These symptoms begin from one to four days after exposure to the virus and last for about 2–8 days. Diarrhea and vomiting can occur, particularly in children. Influenza may progress to pneumonia, which can be caused by the virus or by a subsequent bacterial infection. Other complications of infection include acute respiratory distress syndrome, meningitis, encephalitis, and worsening of pre-existing health problems such as asthma and cardiovascular disease.
The 2009 swine flu pandemic, caused by the H1N1/swine flu/influenza virus and declared by the World Health Organization (WHO) from June 2009 to August 2010, was the third recent flu pandemic involving the H1N1 virus. The first identified human case was in La Gloria, Mexico, a rural town in Veracruz. The virus appeared to be a new strain of H1N1 that resulted from a previous triple reassortment of bird, swine, and human flu viruses which further combined with a Eurasian pig flu virus, leading to the term "swine flu".
The 2009 flu pandemic in the United States was caused by a novel strain of the Influenza A/H1N1 virus, commonly referred to as "swine flu", that was first detected on 15 April 2009. While the 2009 H1N1 virus strain was commonly referred to as "swine flu", there is no evidence that it is endemic to pigs or of transmission from pigs to people; instead, the virus spreads from person to person. On April 25, the World Health Organization declared a public health emergency, followed concurringly by the Obama administration on April 26.
This article covers the chronology of the 2009 novel influenza A (H1N1) pandemic. Flag icons denote the first announcements of confirmed cases by the respective nation-states, their first deaths, and relevant sessions and announcements of the World Health Organization (WHO), the European Union , and the U.S. Centers for Disease Control (CDC).
In March and April 2009, an outbreak of a new strain of influenza commonly referred to as "swine flu" infected many people in Mexico and other parts of the world, causing illness ranging from mild to severe. Initial reports suggested that the outbreak had started in February due to farming practices at a pig farm half-owned by Smithfield Foods. Smithfield Foods stated that it had found no clinical signs or symptoms of the presence of swine influenza in the company's swine herd, or among its employees at its joint ventures in Mexico, that it routinely administers influenza virus vaccination to their swine herds and that it conducts monthly testing for the presence of swine influenza. The new strain was identified as a combination of several different strains of Influenzavirus A, subtype H1N1, including separate strains of this subtype circulating in humans and in pigs. The World Health Organization (WHO) and the U.S. Centers for Disease Control and Prevention (CDC) expressed serious concerns that the new strain, which transmits between humans and has had a relatively high mortality rate in the possible and confirmed Mexican cases, has the potential to become an influenza pandemic. It was reported that, because the virus was already widespread, containment would be impossible. The WHO declared a public health emergency of international concern in response to the outbreak on April 25, 2009.
The pandemic H1N1/09 virus is a swine origin influenza A virus subtype H1N1 strain that was responsible for the 2009 swine flu pandemic. This strain is often called swine flu by the public media. For other names, see the Nomenclature section below.
Influenza prevention involves taking steps that one can use to decrease their chances of contracting flu viruses, such as the Pandemic H1N1/09 virus, responsible for the 2009 flu pandemic.
The 2009 flu pandemic was a global outbreak of a new strain of influenza A virus subtype H1N1, first identified in April 2009, termed Pandemic H1N1/09 virus by the World Health Organization (WHO) and colloquially called swine flu. The outbreak was first observed in Mexico, and quickly spread globally. On the 11th of June 2009, the WHO declared the outbreak to be a pandemic. The overwhelming majority of patients experience mild symptoms, but some persons are at higher risk of suffering more serious effects; such as those with asthma, diabetes, obesity, heart disease, or those who are pregnant or have a weakened immune system. In the rare severe cases, around 3–5 days after symptoms manifest, the sufferer's condition declines quickly, often to the point respiratory failure. Although Ukraine was not (very) affected at first there was on outbreak of the virus in Western Ukraine in early November 2009 that led to the closing of public buildings and cancellation of meetings for three weeks.
The 2017–2018 United States flu season lasted from late 2017 through early 2018. The predominant strain of influenza was H3N2. During the spring months of March–May, influenza B virus became dominant.
