The Poultry Site – Salmonella species are bacteria that can cause foodborne illness in humans when they eat contaminated eggs or other poultry products that are inappropriately cooked. By targeting Salmonella through flock vaccination, contamination of eggs and meat can be reduced without the use of broad scope antibiotics. The poultry industry has been looking for ways to reduce its use of antibiotics due to concerns around the emergence of antibiotic resistant pathogens. Since only a very small portion of Salmonella species can cause foodborne illnesses in humans, a vaccine would need to target only these pathogenic species. Continue reading
The Poultry Site – New research reveals that although there is wide variation in the Clostridium perfringens isolates found in commercial turkeys, it is only those with a particular gene coding for a beta-toxin that are associated with the gut disease, necrotic enteritis. Clostridium perfringens is an important bacterial pathogen, especially in poultry, where it can lead to both subclinical and clinical disease, according to Ulrike Lyhs of the University of Helsinki and co-authors there and at the Finnish Food Safety Authority (Evira), Seinäjoki University of Applied Sciences and Denmark’s DTU National Food Institute.

The Poultry Site – At the same time, the Chinese poultry sector is still having trouble and continues to recover from the crisis caused by avian influenza. The Chinese government just announced that it is giving the industry 300 million yuan (48.5 million dollars) more to help the poultry industry in its recovery. This is added to the 900 million yuan that has already been given to the industry. Aside from the central government subsidies, ten provinces have established preferential policies to support the poultry industry.

ANALYSIS – At its global meeting this week, OIE has agreed new standards on tackling antimicrobial resistance and on broiler welfare. Research to develop a vaccine against necrotic enteritis has taken a step forward and an agreement has been signed between a French-based animal health company and a Chinese university for the development of a new H5N1 influenza vaccine.
The PoultrySite – The agreement was signed in France this week by Dr Marc Prikazsky, Ceva Santé Animale Chairman and Chief Executive Officer and Prof Ren Tao, Vice-Dean of the South China Agricultural University, under the patronage of Stéphane Le Foll, Minister for Agriculture, Agribusiness and Forests, Guillaume Garot, Minister-Delegate for Agribusiness and Martine Aubry, Special Representative for China in the Ministry of Foreign Affairs Ceva said the agreement came about because of the importance of China in the global poultry sector. With a growing population and rising living standards meat consumption is rising, particularly chicken. Continue reading

The Poultry Site – A University of Delaware study has found poultry manure to be less environment-polluting than previous thought. A new report, however, highlights the contribution of livestock to greenhouse gas emissions, while researchers have identified changes in manure management and nutrition that could greatly mitigate the impact from poultry. China is beginning to count the cost of the H7N9 flu outbreaks to its poultry industry.
A new study in the US has found that poultry production brings a lower environmental burden than thought.
Federal environmental programmes have drastically overestimated poultry industry contributions to water pollution, according to a University of Delaware-led study that could trigger changes to river and bay clean-up plans across Delmarva and around the country.
James L. Glancey, a professor in the university’s Bioresources Engineering and Mechanical Engineering departments, said that a multi-state study, based on thousands of manure tests, found that actual nitrogen levels in poultry house manure are 55 per cent lower than the Environmental Protection Agency’s decades-old, lab-based standards.
This work could significantly impact the future of poultry farming in the Chesapeake Bay area, where a forecasting model has been used to guide a federally backed attempt to restore the bay’s health and ecosystems and assign clean-up goals.
Growth in agricultural production has resulted in increased agricultural greenhouse gas (GHG) emissions – with a huge proportion of emissions coming from livestock production, according to a new report from the Worldwatch Institute.
In Japan, researchers comparing the figures for the output of GHG for pig and poultry production in France and Japan found that changing the manure handling process and increasing the use of synthetic amino acids in feeds could be beneficial in reducing GHG output.
Avian influenza can be very costly for the poultry industry, as the Chinese are finding to their cost. Official figures released this week by the China Animal Agriculture Association estimated that since the H7N9 influenza outbreak the poultry industry has recorded losses of more than 40 billion Yuan (US$6.5 billion).
The central government announced this week subsidies of 600 million Yuan ($96.77 million) to support the poultry producers across the country as live bird markets were closed to control the disease and poultry meat demand slumped. Processing companies will receive short-term subsidized loans and local financial institutions are being encouraged to offer credit aid to breeders and companies.
The China Development Bank, the country’s policy lender has said it has issued emergency loans worth 116 million Yuan (US$18.7 million) to help poultry firms cope with the impact of avian flu.
Chinese economists are predicting fewer cases of H7N9 flu in May and a dramatic improvement in market fortunes by mid-summer.
On human cases of influenza A(H7N9), the latest report from China gives the tally as 130 confirmed cases and 35 deaths from the virus.
Global players are also seeing bird flu affect their bottom lines. McDonald’s Corporation, for example, reported comparable sales in April 2.9 per cent below the same month last year in Asia/Pacific, Middle East and Africa, which the company attributed to the impact of bird flu, especially in China.
Bird flu outbreaks have also been reported this week in Nepal (in a backyard flock; virus subtype unknown), in North Korea (H5N1 highly pathogenic virus in domestic ducks) and Tibet (H5N1 in a mixed flock of village poultry).

Science – As many an influenza researcher has observed, the virus that they study is predictably unpredictable. But when a bird flu virus makes the jump to people, it’s easy to predict how humans will react: Pandemic jitters will reverberate around the world, media will scrutinize the actions of public officials, and investigators will begin racing to answer questions about the virus’s origins, spread, and potential threat.
