U.S. egg prices, already at a record after an outbreak of avian influenza earlier this year, will rise even higher in the fall with the onset of the so-called holiday baking season, according to one supplier. While there have been no new outbreaks of the disease since June 17, the industry is concerned with the onset of cold weather in the fall. Photographer: Daniel Acker / Bloomberg via Getty Images.
A farmer tends to a field of white cabbages in Geispolsheim, eastern France on August 06, 2015. Elevated evening temperatures, strong heatwaves and a lack of precipitation has blocked their growth, resulting in what some farmers call a 'white year.' The annual cabbage harvest occurs from August until December, and with estimated September precipitation levels, expect output will be 25 to 50% of normal amounts. The Alsace region accounts for 70% of sauerkraut consumed in France, accounting for approximately 60 farms and 700 hectares of land. Photo credit: AFP PHOTO / FREDERICK FLORIN / Getty Images.
