Improve ozonated water to optimize safety, shelf life of domestic
wild-caught shrimp.
The U.S. domestic shrimp industry faces an economic crisis because
of the high volume of low-priced, pond-raised imported product.
Achieving high product quality is a critical priority for . . .
PCR-based assay detects Salmonella.
A test that detects Salmonella in ready-to-eat meats has been
developed by USDA-ARS scientists. The test relies on polymerase chain
reaction (PCR) technology to detect food-contaminating microbes . . .
Inactivate L. monocytogenes on turkey using high pressure, mild
heat.
Post-process contamination of ready-to-eat meats by L.
monocytogenes is a significant problem. Many measures taken so far have
been unable to successfully eliminate this organism, as evidenced by . . .
Inhibit L. monocytogenes in fish and meat with GRAS plant
extracts.
Listeria species have been isolated from a number of sources,
including soil, decaying vegetable matter, silage, sewage, water, animal
feed, fresh and processed meats, raw milk, cheese, . . .
Prompt refrigeration decreases potential for egg
contamination.
Eggs that contain Salmonella can transmit diarrheal disease to
consumers. Although chickens infected with Salmonella do not deposit
this pathogen inside egg yolks very often, bacteria from the . . .
Develop, validate controls for spore growth during cooked food
cooling and cold holding.
The ability of C. perfringens to form heat-resistant spores and to
grow at a rapid rate at relatively high temperatures is a major factor
leading to foodborne illness. The short generation time, . . .
Segmented-flow aseptic processing.
Segmented-flow aseptic processing technology makes it possible to
process foods containing particulates without many of the problems
inherent in traditional pipe-flow aseptic processing systems. . . .
An electrostatic system.
An electrostatic system that reduces airborne dust and
microorganisms in poultry houses could also help sterilize Salmonella
and other pathogenic bacteria in the dust. The system uses . . .
Investigate controlling microbial contamination from ice.
There have been few studies evaluating the microbial safety of ice.
The microbial contamination of ice leading to outbreaks of
gastroenteritis has been documented on several occasions over the . . .
Compound in cilantro may fight bacteria.
Researchers have identified a compound in cilantro, a key component
of salsa and a variety of other dishes, that kills harmful Salmonella.
It shows promise as a safe, natural additive that could . . .
Predictive microbiology targets poultry pathogens.
Predictive microbiology, which involves the use of modeling
software to forecast the behavior of foodborne pathogens in response to
environmental conditions encountered in food production and . . .
Heat treatments enhance safety of E. coli O157:H7-inoculated mung
bean seeds.
S. typhimurium and E. coli O157:H7 have been associated with
contaminated seed sprouts. Many outbreaks have been traced to seeds
contaminated with low levels of pathogens. For example, strains of . . .
Antimicrobials in pork bologna inhibit L. monocytogenes
post-processing growth.
L. monocytogenes continues to be a major concern to processors of
cooked and ready-to-eat meat products, such as bologna. Scientists at
Colorado State University wanted to evaluate the . . .
Fighting L. monocytogenes with the bioprotective culture
B-SF-43.
L. monocytogenes is of serious concern in food products in which it
can multiply. While the infectious dose is low, the infection may be
lethal. Many ready-to-eat processed foods are at risk. . . .
Bayesian Belief Networks offer advantages when assessing
microbial safety.
The assessment of the microbial safety of foods should involve all
available information and data relevant to a particular hazard. This
information is almost always uncertain. Because biological . . .
Models predict the heat inactivation of L. monocytogenes in
biofilms.
Under most circumstances in food processing facilities, it is
possible to control biofilms by properly cleaning equipment surfaces and
chemically sanitizing them. However, in some cases, usually . . .
Molecular approaches improve product safety and quality, speed
microbe detection.
Rapid, specific detection of pathogenic and spoilage microorganisms
is critical for making a product safe and optimizing its quality.
Conventional microbial detection techniques, which range from . . .
Plum extract.
As little as 3% of plum extract mixed in raw meat is more than 90%
effective in suppressing the growth of major foodborne pathogens, such
as E. coli O157:H7, Salmonella, Listeria, Y. enterocolitica . . .
Washing apples.
Washing apples can reduce the number of organisms on an
apple's surface. Even a plain-water wash can reduce the microbial
counts by 90% or more. Adding a sanitizer or cleaner to the wash water
can . . .
Small, hard-to-find particles.
Small, hard-to-find particles, perhaps hidden in shadowed areas on
poultry carcasses at the processing plant, may be easier to detect. An
advanced imaging system uses hyperspectral imaging to scan . . .
