What is microbial spoilage of meat?
Meat spoilage results in the development of off-odor known as putrefaction. The vacuum- and gas-packaged meat and its products can be spoiled by psychrotrophic Lactobacillus. Spoilage of meat products occurs generally in three types: sliminess, souring, and greening.
What are the 3 main causes of meat spoilage?
Microbial growth, oxidation and enzymatic autolysis are the three basic mechanisms responsible for the spoilage of meat.
What is microbial spoilage?
Microbial Spoilage include the contamination of Pharmaceutical products with the microbes which lead to spoilage of the product affecting Drug safety and quality, and is not intended for use. Shortly Microbial Spoilage is defined as deterioration of pharmaceutical products by the contaminant microbe.
What are the sources of microbial contamination of meat?
During bleeding, skinning, and cutting, the main sources of microorganisms are the body parts of the animal and the intestinal tract. The contaminating bacteria on the knife soon will be found in meat in various parts of the carcass, carried by blood and lymph.
What are the characteristics of spoiled meat?
The appearance of green in particular is not good. Surface slime or skin that feels tacky to the touch are also signs of a rotting product. If your meat displays these warning signs, spoilage bacteria could have taken the meat past its prime, meaning you may taste the decay even after thorough cooking.
What is microbial spoilage and its types?
MICROBIAL SPOILAGE: This refers to damage to food, pharmaceutical products that is caused by micro organisms (bacteria, moulds and yeasts). Micro organisms can grow in almost all kinds of food products. As micro-organisms occur everywhere around us, there is always a risk of microbial spoilage.
What microbes cause food spoilage?
The predominant bacteria associated with spoilage are Brochothrix thermosphacta, Carnobacterium spp., Lactobacillus spp., Lactococcus spp., Leuconostoc spp., Pediococcus spp., Stretococcus spp., Kurthia zopfii, and Weisella spp.
How can we prevent microbial contamination of meat?
Preventing Contamination in Different Kinds of Meat Food poisoning due to microbial contamination of meat can be prevented by cooking the meat thoroughly before consumption and observing good hygiene practices when cooking and handling meat.
What is microbial contamination?
Microbiological contamination refers to the non-intended or accidental introduction of infectious material like bacteria, yeast, mould, fungi, virus, prions, protozoa or their toxins and by-products. 1,2.
How is meat infected with microorganisms?
Raw meat in general contains bacteria, including pathogenic and spoilage ones. As warm-blooded animals naturally carry bacteria such as Salmonella spp. in their intestines, raw meat may be contaminated with bacteria during the slaughtering process such as evisceration and dressing procedures.
What is microbial spoilage PDF?
How can spoilage of meat be controlled?
Freezing is the best method for preserving fresh meat as well as keeping the original characteristics of fresh meat by slowing down the enzymatic reactions and growth of microbes. A temperature of –55 °C is the ideal temperature for frozen meat to completely prevent quality changes and reduce microbial spoilage.
What are the 4 main microbial contaminants?
Microbial Contamination of Food Microbial contamination happens when a food has been contaminated by microorganisms, including bacteria, viruses, mould, fungi, and toxins.
What microorganisms are found in meat?
The most important food borne bacterial pathogens associated with meat are Salmonella spp., Staphylococcus aureus, Escherichia coli, Campylobacter jejuni, Listeria monocytogenes, Clostridium perfringes, Yersinia enterocolitica and Aeromonas hydrophila.
What causes food spoilage PDF?
Causes of Spoilage There are various factors which are responsible for food spoilage such as bacteria, mould, yeast, moisture, light, temperature, and chemical reaction.
How can we prevent microbial contamination in meat?
How can we prevent microbial growth in meat?
Storing meat at temperatures close to 0°C will inhibit the growth of pyschrotrophs. Shelf-life will be extended by avoiding contamination through good hygiene practices. Aerobic bacteria have an absolute requirement for oxygen which limits their growth to the meat surface.

How does fresh meat spoil?
Fresh meat is subjected to spoilage by its enzymes and microbial action. The autolysis changes cause proteolytic action on muscle and connective tissue and hydrolysis of fats. The survival and growth of microorganisms are influenced by the composition of the atmosphere surrounding the meat.
