Backyard Chickens Spread Salmonella

Backyard Chickens Spread Salmonella

Backyard chickens rule the roost at local regulation hearings, and designer coops and exotic chickens are the new status symbols. The media and Web may abound with pictures of cute kids cuddling hens, but pet family fowls are not an unmixed blessing:

“As of September 23, 2014, a total of 344 persons infected with the outbreak strains of Salmonella Infantis, Salmonella Newport, or Salmonella Hadar have been reported from 42 states and Puerto Rico.

31% of ill persons have been hospitalized, and no deaths have been reported.

Epidemiologic, laboratory, and traceback findings have linked this outbreak of human Salmonella infections to contact with chicks, ducklings, and other live poultry from Mt. Healthy Hatcheries in Ohio.

78% of ill people reported contact with live poultry in the week before their illness began.”

Facebook is Like a Disease, But Recovery is Near

Facebook is Like a Disease, But Recovery is Near

“A new study of Facebook has predicted that the social network’s rapid growth will prove unsustainable and that the site will lose 80 per cent of its users between 2015 and 2017.

A group of Princeton researchers has compared Facebook to a highly infectious disease, claiming that after it reaches a certain critical mass of ‘infected’ users, these individuals will ‘recover’ and quit the site.”

— “Facebook is an ‘infectious disease’ and will lose 80% of users by 2017, according to researchers,” James Vincent, The Independent
