A challenge in space travel is how to bring along enough food for the trip. Until now the solution was the growth of vegetables in hydroponic chambers. Professor Christopher House at Penn State University is developing a method of turning human waste directly into edible and nutritious substance. This is done by treating astronauts waste with microbes and producing an edible biomass either directly or indirectly depending on safety concerns. @ https://phys.org/news/2018-01-microbes-astronauts-human-food.html

Human waste may one day be a valuable resource for astronauts on deep-space missions. Now, a Penn State research team has shown that it is possible to rapidly break down solid and liquid waste to grow food with a series of microbial reactors, while simultaneously minimizing pathogen growth.

Panera Bread Recalls All 2 oz. and 8 oz. Cream Cheese Products due to Listeria
FDA announced that out of an abundance of caution, Panera Bread is voluntarily recalling all 2 oz. and 8 oz. cream cheese products sold in its U.S. shops, because single production day showed a positive result for the presence of Listeria monocytogenes. Tests on cream cheese samples manufactured both before and after the production run in question have all come back negative. The recall includes all cream cheese products with an expiration date on or before April 2, 2018, the company said. @ https://www.fda.gov/Safety/Recalls/ucm594219.htm
While there have been no reported illnesses, out of an abundance of caution, Panera Bread is conducting a nationwide preemptive, voluntary recall of all 2 oz. and 8 oz. cream cheese products sold in its U.S. bakery-cafes. This recall was initiated after samples of one variety of 2 oz. cream cheese from a single production day showed a positive result for the presence of Listeria monocytogenes. Tests on cream cheese samples manufactured both before and after the production run in question have all come back negative.

The Multistate Outbreak of Shiga toxin-producing Escherichia coli O157:H7 Infections Linked to Leafy Greens is Over
The CDC announced that as of January 25, 2018, the infection due to leafy greens (CDC never attributed the outbreak to Romaine lettuce) is over. A total of 25 people were infected by STEC O157:H7 from 15 states. Nine ill people were hospitalized, including two people who developed hemolytic uremic syndrome, a type of kidney failure. One death was reported from California. The true source of the outbreak was never discovered and CDC believes that it is a leafy green. Since Leafy greens have a short shelf life, and since the last illness started a month ago, it is likely that contaminate leafs are no longer available. @ https://www.cdc.gov/ecoli/2017/o157h7-12-17/index.html
