Last spring the federal Department of Agriculture told schools that starting in January they could buy ground beef that had been irradiated to kill bacteria and prevent contamination outbreaks.
WASHINGTON — Ten consumer groups that helped promote a landmark food safety law passed in 2010 say the Obama administration is holding up the rules that would put it into effect, a delay they say could cost money and lives this summer, the peak season for food contamination outbreaks.
Dr. Joshua M. Sharfstein, the F.D.A.'s principal deputy commissioner, told the panel that the F.D.A. needed new powers and money to help prevent further food contamination outbreaks, both of which are provided for in legislation that the House passed last year but that has been languishing in the Senate.
Although no single event was identified as the cause of contamination, this outbreak illustrates the vulnerability of water distribution systems.
L.m. contamination in outbreak B was traced to wild swallows defecating in the plant's open cistern water reservoir and a multibarrier failure in the water disinfection system.
Thus, it is important to further evaluate the technology, addressing questions concerning expected variation between closely related strains, background variation, and SNP variation that may arise during sub-culturing possibly obscuring an accurate molecular epidemiological analysis of isolates associated with contamination or outbreak events.
It should be noted that the numbers or organisms used in the BS ISO method are much higher than have been reported in environmental contamination during outbreaks of MRSA (2.5 × 105 vs 500 cfu cm-2; Otter et al., 2011) although in the latter case the organisms may not have been evenly distributed.
"If the risk factor associated with agricultural water use is that closely tied to contamination and outbreaks, there needs to be something now.
While bacterial insusceptibility to in-use concentrations of microbicides is apparently uncommon, there is some evidence of bacteria surviving an antimicrobial challenge, for instance, in microbicide-containing solutions (25), leading to product contamination-related outbreaks (26).
The investigators said they were also investigating a possible connection between the water contamination and an outbreak of Legionnaires' disease that sickened at least 87 people in the Flint region, with nine known deaths, from June 2014 through October 2015.
