Learn best practices for ensuring microbiological safety in food businesses and reducing the risk of foodborne illnesses.
Pathogens are disease causing microorganisms such as bacteria, viruses and parasites. Reducing pathogens to safe levels is a key aspect of food processing. This can be done through a variety of methods, such as pasteurisation, irradiation, or high pressure processing. These methods are used to kill or inactivate harmful microorganisms that may be present in the food.
Minimising the time that food remains at temperatures that allow growth of pathogenic microorganisms is also essential in food processing. This includes ensuring that food is cooled quickly after cooking and stored at appropriate temperatures to prevent bacterial growth.
When attempting to reduce the presence of pathogens in food to safe levels, it is important to use a method that is known to effectively eliminate the risk of these harmful microorganisms. This can include methods such as pasteurization, irradiation, or high pressure processing, which have been proven to effectively inactivate or kill pathogens in food. It is essential for the food business to use a process step that is reasonably known to achieve the microbiological safety of the food to ensure the safety for consumption.
Why is it Important to Achieving Microbiological Safety?
Microbiological safety is important in food because it helps to ensure that the food is free from harmful microorganisms such as bacteria, viruses, and parasites, which can cause foodborne illnesses. These illnesses can range from mild symptoms such as stomach upset and diarrhoea, to more severe and potentially life-threatening conditions such as food poisoning, listeriosis, and E. coli infections.
In addition to causing health problems for consumers, foodborne illnesses can also have significant economic consequences for food businesses. Outbreaks of foodborne illness can lead to product recalls, lost sales, and damage to a company's reputation. Therefore, ensuring microbiological safety in food is critical to protecting public health and maintaining the integrity of the food industry.
Furthermore, food safety regulations and standards require food businesses to implement measures to prevent, reduce or eliminate microbiological hazards in food. This is to ensure that the food produced is safe for consumption and does not pose a risk to public health. Compliance with these regulations and standards is mandatory for food businesses as it is a legal requirement.
Essentially, microbiological safety is important in food as it helps to prevent foodborne illnesses, protect public health, and ensure compliance with food safety regulations and standards.
Ways to Achieve Microbiological Safety in Food Processing
Food businesses can take several measures to achieve microbiological safety when it comes to food processing. Some of these measures include:
Dairy products: Pasteurisation is the most common method used to achieve microbiological safety in dairy products. Pasteurisation involves heating milk to a specific temperature for a certain amount of time to kill any harmful microorganisms that may be present. In addition to pasteurisation, dairy products should be stored at appropriate temperatures to prevent bacterial growth and should be packaged in a way that prevents recontamination.
Meat products: Meat products should be cooked to the appropriate internal temperature to kill any harmful microorganisms that may be present. This includes beef, pork, and poultry. Cook minced meat or chicken patties all the way through to the centre so that juices run clear. Ensure a temperature above 72°C is reached to destroy any pathogens present. Additionally, meat products should be properly stored at appropriate temperatures to prevent bacterial growth.
Egg products: Only eggs, free from cracks and with a clean outer surface should be used for cooking. Eggs should be cooked to appropriate internal temperatures to kill any harmful microorganisms. Additionally, lightly cooked egg products such as condiments and deserts have been previously linked to food borne illness outbreaks. These products, for example, aioli and raw egg mayonnaise must be handled with extra care and stored at appropriate temperatures to prevent bacterial growth. The centre of thoroughly cooked food with shell egg ingredients should reach at least 72°C. A safe alternative to raw egg in food, is use of pasteurised egg pulp.
Seed sprouts: Seed sprouts can be a source of foodborne illness due to the warm and moist conditions required for sprouting. To achieve microbiological safety, seed sprouts should be produced under conditions that minimise the risk of bacterial growth, such as using clean seed, proper sanitising and adequate water treatment. Sprouts should be refrigerated to prevent bacterial growth.
Fruits & Vegetables: Fruits and vegetables should be properly washed and sanitised to remove any surface contaminants, as well as any soil or agricultural chemicals that may be present. They should also be stored at appropriate temperatures to prevent bacterial growth. The use of appropriate sanitisers, such as chlorine, can be effective in reducing the bacterial load on the fruits and vegetables. Additionally, any fresh-cut fruits and vegetables should be refrigerated to prevent bacterial growth.
Fermented milk products: Fermented milk products should be produced under controlled conditions that minimise the risk of bacterial growth, such as using clean milk, proper sanitising practices and adequate temperature control during fermentation. Additionally, fermented milk products should be stored at appropriate temperatures to prevent bacterial growth and should be packaged in a way that prevents recontamination.
These are some measures, when implemented and followed properly, can help to achieve microbiological safety in food processing and ensure that the food produced is safe for consumption. It's important to note that these are not the only measures and each food category may have different specified requirement and regulations, it's important to comply with those regulations and guidelines. Additionally, regular testing and monitoring of the food products can be used to verify that the food is safe and free from harmful microorganisms.
