Potential Farm Sector Effects of 2009 H1N1 “Swine Flu”: Questions and Answers
Summary
In March 2009, a number of cases of an influenza-like illness and severe respiratory infections in
humans were reported in parts of Mexico. These cases were later confirmed to be a strain of
influenza A(H1N1), commonly referred to as “swine flu” and later called 2009 H1N1. By the end
of April 2009, confirmed human cases of 2009 H1N1 infection were reported throughout Mexico,
in parts of the United States, and in several countries worldwide.
Reports of the outbreak—coupled with the use of the initial moniker “swine flu”—initially
caused a downturn in domestic and international pork markets. Domestic pork demand and prices
dropped sharply because of consumer fears that eating pork might result in infection. Several
pork-importing countries also began to consider instituting trade bans and restrictions on live pig
and pork imports from certain countries, including the United States. This initial reaction further
rippled throughout pork and other agricultural markets, such as feed grain and other livestock
markets, as market analysts attempted to speculate about the short- and long-term consequences
of a decline in pork demand and prices.
The Centers for Disease Control and Prevention (CDC), the World Health Organization (WHO),
and the World Organization for Animal Health (OIE) confirm that there is no evidence that the
2009 H1N1 virus is transmitted by food and that humans cannot get the illness from eating
properly handled pork or pork products. Four global organizations—WHO, OIE, the World Trade
Organization (WTO) and the United Nations Food and Agriculture Organization (FAO)—also
issued a joint statement that “pork products handled in accordance with hygienic practices are not
a source of infection.” Also, in the United States, the CDC and the U.S. Department of
Agriculture (USDA) report that there is no evidence at this time that pigs in the United States are
infected with this virus strain.
Administration officials and many in Congress are strongly urging U.S. trading partners to base
any food safety measures on scientific evidence and to act in accordance with their international
obligations under the World Trade Organization (WTO), OIE guidelines, and WTO member
obligations under the Sanitary and Phytosanitary (SPS) Agreement. OIE, among other
international organizations, has stated that there currently is no justification for imposing trade
measures against the importation of pork and pork products. As some countries are continuing to
pursue trade restrictions on North American pork products, some affected exporting countries are
considering formal trade actions in the WTO.
U.S. pork producers hope these efforts to avoid further negative effects on U.S. pork and other
agricultural markets are successful. Initially, many market analysts predicted that the U.S. pork
industry would be adversely affected by expected lower market prices from a decrease in
consumer and export demand for U.S. pork products. The National Pork Producers Council
(NPPC) has sent a letter to USDA to request assistance for the U.S. pork industry to address the
hog sector losses it asserts have been caused by consumer fears in response to the 2009 H1N1
outbreak. Members of Congress from districts with important meat sectors are likely to pay close
attention to developments during 2009.

Potential Farm Sector Effects of 2009 H1N1 “Swine Flu”: Questions and Answers
General Overview1
What Is Swine Flu?
Swine flu refers to strains of influenza (“flu”) that occur naturally and may cause outbreaks of
respiratory illness among wild and domestic pigs. People do not normally get swine flu, but each
year the Centers for Disease Control and Prevention (CDC) identifies a few isolated cases of
human flu that are caused by flu strains typically associated with swine.
What Is 2009 Influenza A(H1N1)?
The current outbreak of concern is caused by a new strain of flu virus that produces illness in
people. It is one of several flu virus strains designated as influenza A(H1N1) for specific proteins
on their surface. This new virus was first detected in people in the United States in April 2009.
Mexico, Canada, and other countries around the world have reported human cases of illness from
the new flu strain. The virus appears to spread from person to person in much the same way as
with seasonal flu.
Why Is This New H1N1 Flu Virus Sometimes Called “Swine Flu”?
This virus was originally referred to as “swine flu” because laboratory testing showed that many
of its genes were similar to flu viruses that normally occur in pigs in North America. Further
study has shown that this new virus is very different from what normally circulates in North
American pigs. It has two genes from flu viruses that normally circulate in pigs in Europe and
Asia, as well as genes from flu strains that normally circulate in humans and in birds. At this time,
there is no evidence that pigs were involved in the transmission of the new flu virus to humans.
For more background information, see CRS Report R40554, The 2009 Influenza Pandemic:
An Overview, by Sarah A. Lister and C. Stephen Redhead. General information is also available
at the CDC and WHO websites.2
Food Safety and Human Health Concerns
Can Humans Get 2009 H1N1 Flu from Eating Pork and Pork
Products?
The CDC, the WHO, and the World Organization for Animal Health (OIE)3 confirm that there is
no evidence that 2009 H1N1 virus is transmitted by food.4 These organizations have repeatedly

3 OIE is the intergovernmental organization responsible for improving animal health worldwide, and is recognized as a
reference organization by the WTO. The organization is still known by its former French abbreviation, OIE (Office
International des Épizooties), though it was renamed the World Organization for Animal Health.

emphasized that humans cannot get 2009 H1N1 flu, or any other type of flu, from eating pork or
pork products. Some have further emphasized the importance of eating properly handled and
cooked pork and pork products, and recommend cooking pork to an internal temperature of
160°F/70°C. This corresponds to the general guidance for the preparation of pork and other meat
to kill all viruses and other foodborne pathogens.
The U.S. Department of Agriculture (USDA) has repeatedly said that the 2009 H1N1 flu is not a
foodborne disease and that eating properly handled and cooked pork or pork products is safe.5
These same arguments were made by medical and veterinary authorities at congressional
hearings.6 The American Veterinary Medical Association (AVMA) further claims that “neither
exposure to pigs nor consumption of pork are risk factors for infection.”7
Four intergovernmental organizations—WHO, OIE, the World Trade Organization (WTO), and
the United Nations Food and Agriculture Organization (FAO)—issued a joint statement that
“pork products handled in accordance with hygienic practices are not a source of infection.”8 The
European Centre for Disease Prevention and Control (ECDC) also states that “influenza virus is
not transmitted by eating properly handled and cooked pork and pork products,” and the
European Food Safety Authority (EFSA) claims it is “not aware of any scientific evidence of risk
to pork consumers from influenza viruses regardless of the type of pork consumed.”9
Given the safety of eating pork and pork products, along with the fact that the disease is primarily
transmitted from human to human, several U.S. and international organizations argued that the
disease should not be called “swine flu.” The CDC, WHO, and OIE, among others, now
recommend instead referring to the disease by its scientific name, influenza A(H1N1) or 2009
H1N1.
Can Humans Get 2009 H1N1 Through Contact with Pigs or with
Uncooked Pork?
The WHO and CDC continue to emphasize that humans typically contact this type of flu through
human-to-human contact, or through contact with infected pigs or environments contaminated
with the virus. However, there is no current evidence of humans acquiring infection directly from
live pigs. OIE further notes that pork and pork products, “handled in accordance with good

hygienic practices recommended by the WHO, the Codex Alimentarius Commission,10 and the
OIE, will not be a source of infection”; and it recommends that “authorities and consumers should
ensure that meat from sick pigs or pigs found dead are not processed or used for human
consumption under any circumstances.”11
EFSA has further stated that it is “not aware of any scientific evidence of risk to pork consumers
from influenza viruses regardless of the type of pork consumed,” including raw meat, although it
is quick to cite longstanding food safety advice that proper cooking kills bacteria or viruses which
may be found in foods, and may prevent possible risk of foodborne illness.12 USDA is also
reminding consumers to practice good food hygiene and “safe food handling and preparation
techniques for all meat and poultry.”13
Do Any Pigs Have the Virus That Has Infected Humans?
In the United States, USDA and other veterinary experts confirm that, as of this date, there has
been no evidence that U.S. swine are infected with the 2009 H1N1 virus; the 2009 H1N1 virus
has also not been reported in feral pigs in the United States.14 USDA and a network of federal
veterinarians, state animal health officials, and private practitioners are regularly monitoring U.S.
swine for signs of significant disease.15
The H1N1 flu virus was found in a swine herd in Alberta, Canada. This incident was reported to
the OIE and was confirmed to have resulted from human-to-pig transmission.16 The Canadian
Food Inspection Agency (CFIA) said it has taken all necessary precautions and has placed the
herd under quarantine. CFIA maintains that Canadian pork continues to be safe to eat.17
The U.S. Animal Health & Productivity Surveillance Inventory (“Inventory”)18 maintained by
USDA’s Animal and Plant Health Inspection Service (APHIS) does surveillance for avian flu,19
but currently does not do surveillance for swine flu because of information limitations:20

Potential Farm Sector Effects of 2009 H1N1 “Swine Flu”: Questions and Answers
Currently, the Inventory includes all animal health surveillance programs conducted by
Veterinary Services, as well as all animal health monitoring studies completed by the National
Animal Health Monitoring System (NAHMS). Information on certain additional animal health
surveillance programs or studies conducted by USDA and other Federal agencies is also currently
included.
Industry reports indicate that APHIS is working on draft guidelines and surveillance plans for the
H1N1 virus. Other industry reports based on information prior to the outbreak also indicate that
the CDC National Center for Immunization and Respiratory Diseases (NCIRD) Influenza
Division (ID) and USDA APHIS Veterinary Services (VS, specifically the National Veterinary
Services Laboratories or NVSL) entered into an interagency agreement regarding swine influenza
virus (SIV) surveillance in July 2008.21 These same reports suggest that a parallel agreement was
reached between CDC and USDA Agricultural Research Service (ARS) for related research
efforts on isolates derived from the APHIS program.
The CDC continues to study the origins of H1N1 and in May 2009 released information
indicating that the virus likely originated in pigs, but that more genetic study and surveillance is
needed.22
There were initial reports that the 2009 H1N1 flu had possibly originated at a business unit of
Smithfield Foods Inc. located in Veracruz, Mexico.23 Smithfield has repeatedly reported that there
is no evidence of the presence of 2009 H1N1 influenza in any of the company’s swine herds or in
its employees at any of its worldwide operations, including those in the United States.24
U.S. Pork Market Effects
How Have U.S. Consumers Reacted to Reports of the Outbreak?
In late April, amid early reports of the spread of 2009 H1N1 flu, retail outlets reported that
consumers were leery of buying pork because of fears that the disease may be linked to pork
consumption. Tyson Foods Inc. also reported a drop in domestic pork sales.25 As domestic sales
fell, retail and wholesale hog prices fell sharply, along with hog and pork-belly futures prices on
the Chicago Mercantile Exchange.26 This drop in prices coincided with seasonal fluctuations in
the hog market that would normally have caused prices to be higher. Economists at Purdue

Potential Farm Sector Effects of 2009 H1N1 “Swine Flu”: Questions and Answers
University estimate that Indiana hog producers were losing about $5 a head on April 24,
compared to estimated losses of about $20 immediately following reports of the initial outbreak
in March.27 Stock analysts also reportedly downgraded the stock of Tyson Foods Inc. and
Smithfield Foods Inc. and lowered annual earnings estimates for these companies.28
Reduced demand for pork could have adverse ripple effects throughout the hog sector, resulting
in production changes as producers respond to lower prices. Hog producers may choose to curtail
planned farrowing and/or decrease their demand for weaned feeder pigs; or they may choose to
liquidate or reduce herd sizes, if lower prices result in low/negative meat-to-feed profit margins.
As of the end of April, consumers were still confused by how humans can get the 2009 H1N1 flu.
For example, a phone survey conducted by the Harvard School of Public Health on April 29
asked 1,067 consumers about the ways humans can get the 2009 H1N1 flu. Among listed choices,
respondents were asked about whether each was a possible way of contracting the disease. Most
(83% of respondents) said: “From being in close contact with someone who has swine flu—that
is, within about three feet.” However, others responded that humans can get the 2009 H1N1 flu
“From being near someone who has swine flu, but not in close contact—that is, being at thirty
feet away” (29% of respondents) and “From coming in contact with pigs” (34%). Others
indicated that they thought humans can get the 2009 H1N1 virus “From eating pork” (13%).29
How Have U.S. Trading Partners Reacted to Reports of the
Outbreak?
Citing public health and safety concerns, several countries have initiated or implemented steps to
ban or restrict U.S. pork or pork products. Reports differ among governmental, industry, and other
media sources regarding which importing countries are instituting restrictions and which
imported product lines will be targeted. Following the initial reports of the outbreak, the U.S.
Meat Export Federation (USMEF) and other media reports confirmed that several countries,
among them China (but not Hong Kong) and Russia, had instituted official full or partial trade
restrictions on U.S. pork products (see box).30 By the following week, some countries had
announced that they would lift their import ban; however, other countries announced that they too
would ban all pork imports.31 Many of these countries have also imposed these same restrictions
on Mexican and Canadian pork and pork products. South Korea has instituted a partial ban,
suspending imports only of live swine, but has not suspended trade for pork imports. Conflicting
media reports have listed some other countries that to date have not imposed trade restrictions,
such as Bolivia, Costa Rica, Guatemala, and the Philippines.32

Potential Farm Sector Effects of 2009 H1N1 “Swine Flu”: Questions and Answers
Restrictions vary by country. For example, Russia has announced it will restrict all livestock and
meat products, including beef, pork, and poultry, from selected states, and restrict all pork from
several other selected states; China is restricting pork and live pigs from most, but not all, U.S.
states. Some countries are banning all pork products, whereas other countries are restricting
certain products only. The United States is among the largest supplier of pork products to both
China and Russia.33
How Important Are Export Markets to the U.S. Pork Sector?
Foreign sales are a critical source of income for the U.S. meat and poultry industries, with the
United States now exporting more than one-fourth of its annual pork production.34 Fresh, chilled,
and frozen pork products account for the bulk of U.S. annual pork exports (Table 1). China and
Russia are among the top ten largest international markets for U.S. pork, and represented 15%
percent of total U.S. pork exports in 2008 (Table 2).
What Share of U.S. Pork Exports Is Represented by Countries
Restricting Trade?
Countries that have instituted full or partial bans, as of mid-May, on U.S. pork exports as a result
of the 2009 H1N1 flu outbreak represent 13%-16% of U.S. annual pork trade, based on trade data
for the past three years from 2006 through 2008 (Table 1). The bulk of this lost potential is the
result of restricted trade from Russia and China. The other countries that are restricting U.S. pork
imports comprise a small overall share of annual U.S. pork trade. Japan, the largest U.S. market
for U.S. pork, with more than one-third of the market in 2008, has repeatedly indicated that it will
not restrict U.S. pork exports; also, Hong Kong, despite mainland China’s trade restrictions, has
indicated that it will not restrict trade.35

What Are the International Obligations of Our Trading Partners?
Under WTO rules, health and safety measures applied to imports must be supported by scientific
evidence. Administration officials and many in Congress are strongly urging all U.S. trading
partners to base any food safety measures on scientific evidence and to act in accordance with
their international obligations under the WTO, OIE guidelines, and WTO member obligations
under the Sanitary and Phytosanitary (SPS) Agreement.36
Regarding 2009 H1N1, OEI—the global animal health standards organization—asserts that “the
imposition of ban measures related to the import of pigs and pig products do [sic] not comply
with international standards published by the OIE and all other competent standard setting
international bodies for animal health and food safety.”37 Accordingly, it is argued, there currently
is no justification for imposing trade measures against the import of pork and pork products based
on 2009 H1N1.
36 SPS measures refer to any of the laws, rules, standards, and procedures that governments employ to protect humans,
other animals, and plants from diseases, pests, toxins, and other contaminants. See also CRS Report RL33472, Sanitary
and Phytosanitary (SPS) Concerns in Agricultural Trade, by Geoffrey S. Becker.

Potential Farm Sector Effects of 2009 H1N1 “Swine Flu”: Questions and Answers
What International Actions Are Being Taken?
As some countries continue to pursue trade restrictions on North American pork products, some
affected exporting countries are considering formal trade actions within the WTO. The U.S. Trade
Representative (USTR) is urging all U.S. trading partners to base any food safety measures on
scientific evidence in accordance with their international obligations. In a statement, USTR said
that “restrictions on U.S. pork or pork products or any meat products from the United States
resulting from the recent outbreak do not appear to be based on scientific evidence and may result
in serious trade disruptions without cause.” USDA also has emphasized that “the science is clear
that consuming or handling pork, consistent with safe handling practices, is of no risk to
consumers.” 38 Many in Congress also are urging U.S. trading partners to base these decisions on
science, and therefore not to ban imports of U.S. pork.39
Media reports indicate that Mexico has issued a statement asking its trading partners to “eliminate
any restrictive measures established on Mexican products, which are not in accordance with the
scientific information available or with their international obligations”; other reports indicate that
Canada has said it will consider bringing a WTO challenge to China’s ban on imports of
Canadian pork.40 The European Union (EU) Standing Committee on the Food Chain and Animal
Health also asserts that, based on the available evidence, trade restrictions are not justified.41
Many regard the trade bans and restrictions as politically motivated or intended to protect pork
producers in their own countries. Russia, for example, is not competitive on the global market in
red meats and poultry, and its domestic production has not kept pace with consumption as
incomes rise, even though government policies have attempted to encourage domestic production.
In recent years, imports have accounted for a growing share of Russian pork consumption, and
reached more than 50% of supplies in 2008.42 Russia periodically has imposed SPS measures that
have impeded U.S. meat and poultry imports in recent years. In March 2002, Russia announced a
ban on U.S. poultry imports over the possible presence of avian influenza in the United States.
U.S. officials countered that the ban was not scientifically defensible and was discriminatory.43
China is among the world’s largest pork markets and producers, and imports account for a
negligible share of overall supplies. However, imports have grown in recent years and are
important to exporting nations such as the United States, given the sheer size of China’s market.
The National Pork Producers Council (NPPC) has said it expects current restrictions on U.S. pork
exports because of concerns about the H1N1 virus to be temporary, particularly as international
authorities continue to emphasize that the virus is transmitted through human contact and not
through pork consumption.44 However, many producers are concerned that these initial trade
restrictions will be difficult to remove, once fully instituted. For example, EU’s livestock beef

Potential Farm Sector Effects of 2009 H1N1 “Swine Flu”: Questions and Answers
production has not returned to the level it maintained prior to the outbreak of bovine spongiform
encephalopathy (BSE), commonly known as “mad cow disease.” BSE also affected U.S. beef
producers in 2003 when the first U.S. case was announced.45 Russia was among the many
countries to ban U.S. beef, although it not had been a major purchaser of such products.
Other U.S. Farm Sector Effects
How Have Other U.S. Agricultural Markets Been Affected by the
Outbreak?
Initially, as domestic pork sales fell in response to the spread of the H1N1 flu, futures prices for
corn, soybeans, and wheat declined sharply.46 This was a result of concerns that lower pork
demand and production could reduce demand for other commodities, including U.S. feed grains
and protein meals (like soybeans), as well as other farm inputs. Analysts predict that feed prices
will likely continue to be very volatile, but difficult to anticipate.47 For example, grains prices
have moved higher since their initial drop following early reports of the outbreak.48 In other
livestock markets, wholesale beef and cattle futures prices were initially higher following reports
of the outbreak.49 The U.S. produce sector also expressed concerns about possible restrictions on
fresh produce trade with Mexico and the processing of agricultural guest labor workers from
Mexico because of the 2009 H1N1 outbreak, but these fears so far have not materialized.50
What Are the Estimated Aggregate Market Costs to the U.S.
Agriculture Sector?
Initial reports of the aggregate economic effects to the farming sector—especially to U.S. hog
producers—were grim. Early estimates by analysts at the University of Missouri have estimated
that the U.S. pork industry could see losses of up to $400 million in the next few months, given
lower market prices.51 More recent estimates by the University of Missouri, as reported by USTR,
indicate that the U.S. pork industry may face losses of about $270 million in income in the second
quarter of 2009 alone, based on market conditions in the first few days since the virus was
identified.52 Analysts at Purdue University have estimated that from 25% to 33% of U.S. hog
producers may be “forced to reconsider their positions in the industry.”53

Potential Farm Sector Effects of 2009 H1N1 “Swine Flu”: Questions and Answers
In its May 2009 outlook report, USDA revised its second-quarter hog prices downward to reflect
lower prices in April due to the negative effects of H1N1 flu virus. However, USDA is predicting
that prices will recover and is not altering its outlook for hog prices during the second half of
2009, based on expectations that market disruptions from trade restrictions and consumer
concerns will be short-lived.54 In mid-June, Smithfield Foods Company reported that, although it
remains concerned about restrictions on international markets, the company believes that H1N1
had “only a short-term effect on U.S. fresh pork demand,” with “no significant effect on the
quarter” based on the company’s consolidated income statement.55
Analysts also predict that 2009 H1N1 will have less of an impact on the pork industry than BSE
had on the beef industry in 2003 or avian influenza on the poultry industry in 2005-2006.56
Analysts with World Perspectives, Inc., note that although pork prices have declined, supplies are
also lower than last year, and it remains unclear whether pork sales have actually decreased.57 In
other markets, analysts at the University of Illinois highlight that “grains have had quite a rally in
prices, after the market’s initial ‘knee-jerk’ reaction,” although pork prices continue to be lower.58
Among meat packers, analysts predict that the trade restrictions will have less of an effect on
larger diversified companies, such as Cargill Inc. and JBS S.A., but could affect single-product
firms such as National Beef Packing Company and companies already operating under financial
distress, such as Pilgrims Pride.59
Nevertheless, the negative effects of the flu, coupled with rising costs for feed and other costs,
remain a concern to those in the U.S. hog sector.60 In early May 2009, NPPC has sent a letter to
USDA to request assistance for the U.S. pork industry to compensate for losses it says it has
incurred since the 2009 H1N1 outbreak. Specifically, NPPC is asking USDA to implement a
purchase program for $50 million of pork products to help boost cash hog prices; to work with
U.S. trading partners to remove all restrictions on exports of U.S. pork and pork products; to
develop a comprehensive surveillance program for early detection of swine diseases; and to work
to keep open the border between the United States and Canada to allow for movement of hogs. 61
Members of Congress from districts with important meat sectors are likely to pay close attention
to developments during 2009.
