There are a number of testing methods when it comes to Listeria monocytogenes, here Solus Scientific, a PerkinElmer company, outlines a few choices.
The test may rapidly and sensitively distinguish subtypes of Salmonella, making its origin easier to track, the Journal of Molecular Diagnostics has reported.
The scientists have reportedly developed a method to determine Salmonella serotypes in just two hours, and the whole identification process within eight hours.
The technique is said to reduce the time for determining whether food is contaminated with salmonella from a number of days to less than eight hours.
Heterosis, hybrid vigor, or outbreeding enhancement is said to be the improved or increased function of any biological quality in a hybrid offspring, which can potentially alter the dominance and over-dominance hypothesis in cattle.
Scientists from the American Phytopathological Society have developed an online tool called Uniqprimer, which aims to quickly and automatically design species-specific DNA tags for detecting pathogens using DNA testing.
What is an isotope fingerprint? How can it help detect and prevent food fraud? New Food finds out from Thermo Fisher Scientific. Watch the video below....
The WUR test is considered faster and more practical than laboratory tests and is said to allow banana farmers and authorities to take immediate measures once suspect plants test positive for the fungus.
The detectors sniff out biogenic amines (BAs), which give decomposing meat its bad odour.
