ULTRASOUND IMAGING IN THE FOOD INDUSTRY - WHAT WE CAN LEARN
Here at Vet Image Solutions we know just how versatile ultrasonography can be – whether it’s a veterinarian scanning a cat, to a breeder examining their dog for pregnancy, to a farmer using ultrasound imaging on their herd of cows, veterinary ultrasound can be used on all kinds of animals. This week we continue exploring this versatility by looking at a slightly more unusual use for ultrasonography within the food industry. A paper published earlier this year (2018 Jan 8;269:12-18) by Duarte ALA et al., ‘Ultrasound improves antimicrobial effect of sodium dichloroisocyanurate to reduce Salmonella Typhimurium on purple cabbage’ in the International Journal of Food Microbiology is the focus for this week, and the abstract and link to the full article can be found by clicking here.
The researchers sought to use three different chemicals with or without ultrasonography in order to assess the effects on the resultant quality of purple cabbage. In order to more fully understand the usefulness of ultrasonography in such a setting, cabbages were also infected with a specific type of bacteria in conjunction with naturally occurring bacteria to see if their numbers (of the bacteria) reduced following treatment.
The results were very interesting and implicate a role for ultrasound in lowering the bacteria on the purple cabbages. Ultrasound used in conjunction with some of the chemicals investigated appeared to be the most potent way to remove bacteria on the cabbages. Importantly, this reduction in bacterial content was not accompanied with other changes (such as the appearance) which may not be wanted.
These studies are important in expanding our knowledge of ultrasonography and the range of applications this technique has. It is almost guaranteed that the uses for veterinary ultrasound are sure to grow and grow, thanks to an increased understanding of how ultrasonography works alongside constant advances in ultrasound technology.
