A CDC infographic on how antibiotic-resistant bacteria have the potential to spread from farm animals. Antibiotic use in livestock is the use of antibiotics for any purpose in the husbandry of livestock, which includes treatment when ill (therapeutic), treatment of a group of animals when at least one is diagnosed with clinical infection (metaphylaxis [1]), and preventative treatment ...
In a literature review conducted by the Review of Antimicrobial Resistance 100 out of 139 studies found evidence of a link between antibiotic use in animals and antibiotic resistance in consumers. [6] When a gram-negative bacterial infection is suspected in a patient, one of the first-line options for treatment is in the fluoroquinolone family.
The organoleptic quality of the food refers to its sensory properties, that is its look, taste, smell and texture. Examples of hurdles in a food system are high temperature during processing, low temperature during storage, increasing the acidity , lowering the water activity or redox potential , or the presence of preservatives .
Probiotics are live microorganisms or viable spores which support the development of a beneficial gut microflora.Probiotic bacteria (e.g. from the genera Lactobacillus, Bifidobacterium, Enterococcus) counteract undesired microorganisms such as Salmonella or E. coli by blocking receptors on the gut wall, production of antimicrobial substances or activation of the immune system.
In addition to lactic acid bacteria, yeasts also have been reported to have a biopreservation effect due to their antagonistic activities relying on the competition for nutrients, production and tolerance of high concentrations of ethanol, as well as the synthesis of a large class of antimicrobial compounds exhibiting large spectrum of activity against food spoilage microorganisms, but also ...
Food preservation includes processes that make food more resistant to microorganism growth and slow the oxidation of fats. This slows down the decomposition and rancidification process. Food preservation may also include processes that inhibit visual deterioration, such as the enzymatic browning reaction in apples after they are cut during food ...
A preservative is a substance or a chemical that is added to products such as food products, beverages, pharmaceutical drugs, paints, biological samples, cosmetics, wood, and many other products to prevent decomposition by microbial growth or by undesirable chemical changes. In general, preservation is implemented in two modes, chemical and ...
An illustration shows the different effects of the bacteriostatic agent and bactericidal agent. A bacteriostatic agent or bacteriostat, abbreviated Bstatic, is a biological or chemical agent that stops bacteria from reproducing, while not necessarily killing them otherwise.
