In a victory for energy companies, the administration plans to roll back rules covering methane leaks and the “flaring,” or burning, of the potent greenhouse gas.
The resistant E coli sublineage ST131-H22 has become established in poultry.
Cargill Meat Solutions, a Fort Morgan, Colo. establishment, is recalling approximately 25,288 pounds of ground beef products that may be contaminated with E. coli O157:H7, the U.S. Department of Agriculture’s Food Safety and Inspection Service (FSIS) announced today.
Earlier conventional lab tests highly suggest that the Ebola Zaire species is the cause of the latest outbreak, but the WHO said genetic sequencing is needed to confirm the finding. Ebola Zaire is the species most deadly to humans. Genetic characterization will help guide the use of vaccines and drugs; VSV-EBOV, the candidate vaccine furthest along in clinical trials, targets the Ebola Zaire species and could be used if the new outbreak strain matches the vaccine strain. Ebola Zaire caused both the earlier DRC outbreak that was declared over on Jul 24 and the devastating 2014-16 outbreak in West Africa.
Earlier this week, a new appointment for chief scientist at the U.S. Department of Agriculture (USDA) was announced, and it’s a 30-year veteran of Dow Agrosciences. Really?
Administration officials are touting the fact that Scott Hutchins is actually a scientist — unlike their last pick. The nomination of Sam Clovis, an openly racist radio talk-show host and Trump campaign team alum, was withdrawn last November, after it generated outrage across the political spectrum.
Any old scientist?
So yes, Hutchins is a scientist. Does that qualify him to guide USDA’s $2.9 billion research budget? Um, no.
To see if small mammalian predators influence tick infection rates, researchers placed camera traps at dozens of sites throughout Dutchess County in the summers of 2012 and 2013. Trap visitors included coyote, fox, bobcat, fisher, raccoon, and opossum. Then the investigators surveyed and tested ticks at the camera trap sites.
Locations with high predator diversity had lower infection prevalence of nymphal ticks than sites dominated by coyotes. Numbers of nymphal ticks were lowest where forest cover was higher, and bobcats, foxes, and opossums were associated with a reduction in tick infection.
The chlorine washing of food, the controversial “cleaning” technique used by many US poultry producers who want access to the British market post-Brexit, does not remove contaminants, a new study has found. The investigation, by a team of microbiologists from Southampton University and published in the US journal mBio, found that bacilli such as listeria and salmonella remain completely active after chlorine washing. The process merely makes it impossible to culture them in the lab, giving the false impression that the chlorine washing has been effective. Apart from a few voluntary codes, the American poultry industry is unregulated compared with that in the EU, allowing for flocks to be kept in far greater densities and leading to a much higher incidence of infection. While chicken farmers in the EU manage contamination through higher welfare standards, smaller flock densities and inoculation, chlorine washing is routinely used in the US right at the end of the process, after slaughter, to clean carcasses. This latest study indicates it simply doesn’t work.
We confirm the existence of overnight “sleep” movement for some trees, but conclude that circadian movement is a variable phenomenon in plants, probably controlled by a complex combination of anatomical, physiological, and morphological factors.
