Confirmation of Source DHHS releases findings on 11/9/12
• 106 illnesses, additional 160 (fairgoers not ill) in case control study
• Two specific strains of E.coli O157:H7 identified from environmental samples at fairgrounds – Petting Zoo Area – Parking lot “downhill” from petting zoo
• Heavy rains 6 of 11 days at fair noted

Cleveland County Fairgrounds, Shelby, NC

What’s Next? • Final report from DHHS released 1/8/13
– “The requirements set forth in Aedin’s Law have done a great deal to protect the public in venues such as the CCF. Nonetheless, Aedin’s Law cannot guard against all possibilities. Ruminant animals are a known reservoir for STEC; environmental contamination in outbreak settings is not uncommon; and the provisions of the NASPHV animal contact compendium may not be adequate to prevent illness in certain situations.”
• DHHS expects to convene task force of experts and interested parties to review findings and discuss future

H3N2v Influenza
• Novel influenza A viruses are different than current circulating human H1 and H3 viruses
• Since 2007, novel influenza A infections in humans are nationally reportable to National Notifiable Diseases Surveillance System
• When swine influenza infects humans, they are referred to as “variant” viruses (denoted as “v” at end of subtype designation)

Variant Influenza Virus Case history
• Before 2005, 1 to 2 cases per year of swine flu viruses infecting people
• 2005-2011, variant viruses H1N1 and H3N2 identified more frequently, 3 – 5 cases per year.
• Aug. – Dec, 2011 there were 12 human cases

203 cases at fairs
• 98% had contact at fair – Direct = 77% (many exhibited hogs) – Indirect = 16%

– “Attended Fair” = 5%

• Pregnant women

What Did Fairs Do? • Temp check pigs before unloading • Stepped up monitoring of pigs in barns by vets • Additional signage
– Caution to hi-risk – Wash hands
• Additional hand wash stations (and sanitizers) • Those with prior CPP workshop training were
better prepared to answer media inquiries

What Did Fairs Do?
• Release pigs early • Special
communication with exhibitors
• Step up cleaning protocol
• Barriers to prevent guest access to pigs
• Elimination of all pigs at fair
![Page 26: E. coli Status Report - Markham Fair · 2013-03-06 · 306 cases • 10 states • 29 fairs associated with human cases • 16 hospitalizations ... CDC, USDA, NPB, various state public](https://reader033.fdocuments.net/reader033/viewer/2022060313/5f0b72f17e708231d430926e/html5/thumbnails/26.jpg)
Expectations for Future Ideas circulating
• Shorten length of time pigs are on grounds to less than 72 hours
• Vaccination of pigs prior to fair exhibition • Daily monitoring of pigs in barns • Increase emphasis on good hygiene (exhibitors
and guests) • Encourage sick exhibitors to stay home • Increase communication with exhibitors
(awareness, last minute changes, etc.)

Expectations for Future Ideas circulating
• CDC Compendium will probably recommend increased awareness (signage) for high-risk populations (including avoidance of pig exhibits) as well as exhibitors wearing personal protective equipment (PPE such as masks, gloves, clothing) if pigs are ill.
• The “Swine Influenza Working Group” (representatives from CDC, USDA, NPB, various state public health and animal health agencies) invited IAFE to be represented. Measures to minimize influenza at exhibitions are in draft, to be published in next two months.
• It is expected the National Pork Board will issue recommendations.

Other Concerns
• Salmonella – No handling of baby poultry by anyone <5 years – No handling of reptiles, turtles, etc. by anyone <5 – CDC will recommend no reptiles, turtles, etc. be used as
prizes in carnival/fair games
