Physical contamination is the entry of unwanted solid metals and nonmetals into food. Examples include glass, metal, plastic and hair. It has become essential for the food industry to observe the necessary steps to avoid physical contamination of food. Preventing contamination is not just about compliance; it is about safeguarding public health and maintaining trust in the food supply chain.
How To Preserve Food And Why It�s Important
Food preservation keeps food safe to eat for a longer time, by stopping bacteria and spores from growing.What is Food Preservation?Food preservation primarily provides protection from germs. It is the process that extends the shelf life of food by protecting it from microbial contamination.�The time duration that food stays good to eat is called its "shelf life." Perishable food is used sooner because its shelf life runs out quickly. Non-perishable food has a long shelf life and can be stored for later use.How Do You Preserve FoodThere are different ways to preserve food. Here are some common ones:Putting food in the fridgeStoring food in the freezerPutting food in cans made of aluminium or tinAdding salt or sugar to foodLetting food fermentTreating food with heatThese methods help stop bacteria from growing and spoiling the food. They either take out water, keep it cold, seal it in a vacuum, or heat it to make it last longerPutting Food in the FridgeStoring food at a low temperature between 0�and 4 degrees celsius, slows down bacterial spread and keeps food fresh.Refrigerated food remains out of the "Danger Zone" Temperature at 40 �F and 140 �F� (8 �C and 60 �C). At the danger zone temperature, the growth of bacteria is twice as rapid.Fridge storage of food at below 5 �C for up to 3 to 4 days in most cases is preferred to prevent spoilage.Food leftovers should be stored within 2 hours to prevent prolonged exposure to room temperature.It is important to arrange food correctly stored in separate compartments or sealed containers, to prevent cross-contamination.Ideally, food items stored first must also be consumed first. The First-In First-Out (FIFO) rule confirms that food is used before it expires, reducing food waste.For more information, read our blog article, �The FIFO Food Stock Rotation.�Storing Food in the FreezerFreezer temperature usually ranges between -18�C and 0�C.�Freezing food slows down the growth of bacteria and enzymatic activity, preserving freshness and nutrients.Food stored in a freezer can remain preserved for up to several months.�It is important to cool food before freezing it.�Freezing causes water molecules to form crystals of ice.�The method reduces the amount of free water needed for microbial and enzymatic reactions.�Always maintain the freezer to the lowest temperature for proper crystal formation.�Freezing does not aim to sterilise food, it keeps the quality of food intact.Putting Food in Cans Made of Aluminium or TinStoring food in tin containers protects food from bacterial toxins.The container is sterilised using intense heat.�High temperatures in a pressure canner destroy harmful microorganisms like Clostridium botulinum spores.The required temperature for destroying these spores is 240�F (116�C).�During canning, the heat treatment kills vegetative bacteria, yeasts and moulds.�The high temperature also interferes with the process of microbial cell wall synthesis, protein production and metabolism.�Food is stored in a can under airtight conditions. The can is further heated to destroy microorganisms.�High-acid foods (low PH) such as fruits and pickles undergo low heat intensities during canning.Foods low in acidity require high temperatures for canning. Examples include meat and soups.Adding Salt or Sugar to FoodSugar and salt act as natural preservatives in food by reducing water activity and slowing microbial growth.Wet or dry sugar/salt treatment can help preserve food through desiccation or extreme dying.Drying occurs by osmosis when water moves from a region of high concentration to a region of low concentration.Water in food responsible for bacterial growth moves out into the salty environment of low water concentration.Sugar and salt-driven osmotic pressure leads to unfavourable conditions for microorganisms in water-starved environments.Letting Food FermentFermentation is the oldest method of food preservation that preserves the freshness of food through bacterial activity.�Fermentation causes acidification that inhibits the growth of microorganisms such as yeast, bacteria and moulds.�Microorganisms produce alcohols and organic acids from sugars. As a result, unfavourable environmental conditions are created for bacterial spread. The quality of food is preserved, and the shelf-life is prolonged.�Some microorganisms produce preservative compounds that help maintain the safety and quality of fermented foods.�Usually, there is no need to add chemicals or artificial additives in fermented foods.Fermentation occurs in an anaerobic environment that slows the growth of aerobic bacteria.The process of fermentation prevents unwanted oxidation of food.�Fermentation produces vitamins, enzymes, and bioactive compounds to maintain the nutritional value and health benefits of fermented foods.Treating Food with HeatPasteurisation reduces microbiological presence in solid and liquid foods by using high intensities of heat.�The process does not kill microbial growth at 100%.�Pasteurised foods have a limited shelf life and require refrigeration due to the presence of surviving microorganisms.�The main difference between the process of sterilisation in canning and pasteurisation is that sterilisation completely destroys microorganisms and spores. On the other hand, pasteurisation reduces microbial load with the presence of some surviving microorganisms. It does not change the nutritional value and taste of food.�Pasteurisation �Holder Method� Conditions: 149�F (65�C) for 30 minutesPasteurisation �High Temperature/Short Time (HTST)� Conditions: 190�F (88�C) for 15 secondsWhich Food Preservation Method is the Best?The most suitable preservation method depends on factors such as the type of food, and the desired shelf life. For example, canning is suitable for preserving fruits and vegetables. Freezing is used for preserving meats and seafood.Bacterial Spores in FoodThe shape of bacterial spores is oval or sphere-like. They are small dormant forms of bacteria that are highly resistant to heat, desiccation, and chemical agents. They survive high temperatures, up to 150�C (302�F). Spores can multiply and lead to food spoilage and potential health risks.Importance of Food Preservation in Food SafetyPrevents the growth of harmful microorganisms that cause foodborne illnessesProlongs the shelf life of perishable food items�Reduces the risk of consuming contaminated foodProtects consumers from foodborne pathogens such as Salmonella, E. coli, and ListeriaMinimises food waste by allowing extra food to be storedSaves money and reduces the environmental impact of food production and distribution. .second-cta-block .main-heading { font-weight: bold; font-size: 22px; } .second-cta-block .book-now { background: #DF3D52; color: #FFFFFF !important; border-radius: 8px; } .second-cta-block .second-heading { font-size: 17px; } .second-cta-block .card { border: 0 !important; } .second-cta-block .card-body { border: 1px solid #909090; box-shadow: rgba(0, 0, 0, 0.16) 0px 1px 4px; border-top-right-radius: 100px; border-bottom-right-radius: 100px; background: #fdf9ee; } .second-cta-block .image-wrapper { height: 330px; position: absolute; right: -60px; top: calc(50% - 210px); /* Center the image vertically */ } .second-cta-block .image-wrapper img { height: 100%; } .second-cta-block .trustpilot-widget { width: 256px; } .cta-heading-section { width: 75%; } @media screen and (max-width:991px) { .second-cta-block { padding-top: 100px; } .second-cta-block .card-body { border: 1px solid #909090; box-shadow: rgba(0, 0, 0, 0.16) 0px 1px 4px; border-radius: 19px; border-radius: 14px; background: #fdf9ee; } .cta-heading-section { width: 100%; padding-top: 50px; } .second-cta-block .image-wrapper { height: 270px; right: 0; position: absolute; left: calc(50% - 90px); top: calc(50% - 315px); } } Get Online Food Safety Courses Food Hygiene And Safety Check the Course Rated Excellent on major review sites Disadvantages of Food Preservation MethodsFood preservation methods offer several benefits, but they also have some drawbacks:Canning and drying can lead to a loss of vitamins and minerals in food.Some preserved foods have reduced palatability due to changes in texture and flavour.Packaging materials used in food preservation methods, such as cans and plastic containers, can have negative environmental consequences.FAQsWhat is the difference between pasteurisation and sterilisation?Sterilisation completely eliminates microorganisms and spores.

According to the Food Standards Agency, there were an estimated 2.4 million cases of food-related diseases in 2018.�The causative agents identified were salmonella and campylobacter, the most common causes of food poisoning in people.Business-Related Impacts of Food ContaminationAs the food industry has become highly competitive in the UK, even slight negligence in terms of food contamination can result in far-reaching negative impacts on the brand name. This can include:Customer dissatisfactionDamage to brand reputationDecline in the food business's economic growthMethods of Food ContaminationPhysical, chemical and microbial contamination of food can occur through direct contamination or cross-contamination. These methods introduce contaminants into food products and substances.Direct Food ContaminationDirect food contamination is the pollution of those sources from which raw food is extracted, such as plants and animals. This is due to chemical and biological contaminants in the air, soil or water in the natural habitat of the food source.�Example: Shellfish contaminated by toxic marine algae is an example of direct food contamination.Food Cross-ContaminationCross-contamination is the transfer of contaminants among different kinds of food, between food and unclean equipment and from food handler to food. It usually occurs during improper food handling. Chemical and microbial contaminants enter food products during any one of the stages of food preparation.�Example: Raw food products like meat and poultry contaminate other foods and kitchen utensils. Microbes can be transferred from one food to another by sharing the same knife or another unwashed tool. This is an example of food cross-contamination.�Which Food Hygiene Training Course Certificate Do I Need?The food safety and hygiene certificate you need depends on your job and the type of food business you work in.Level 2 Certificate: This is for people who handle, prepare, cook, or package food, like chefs, kitchen assistants, baristas, childminders, food shop workers, market stall holders, bakers, and food factory workers.Level 3 Certificate: This certification is for those who manage or supervise food-related work, like head chefs, kitchen managers, restaurant managers, food shop supervisors, quality controllers, and factory supervisors. This level covers advanced food safety management and HACCP.You can also choose food hygiene courses based on your industry:Catering: For businesses that serve food directly to customers, like restaurants, cafes, and canteens.Retail: For businesses selling packaged food, like shops, delis, and supermarkets.Manufacturing: For businesses that process and pack food, like factories and warehouses.Food hygiene training is important for everyone in the food industry, from factory workers to restaurant supervisors to supermarket employees.

How to Reheat Food Safely More Than Once
Ideally, do not reheat food more than once. However, under appropriate conditions, food reheated two or three times is safe to eat. When it comes to reheating leftover food more than once, whether they are home-cooked meals or dine-in takeaways, appropriate heating and storage temperatures play an important role in determining food safety.The Safety of Reheating FoodFood reheated more than once is safe if correct temperatures and proper handling conditions are followed. Although fresh food is ideal, you can safely reheat it at an appropriate temperature, using proper storage methods and suitable cooking tools.How Many Times Can You Reheat Food?It is best to eat fresh food, right after it comes out of the oven or off the stove. Food should be reheated only once, as suggested by the Food Standards Agency (FSA).If you are unsure about the odour, texture or palatability of leftover food, it is best to dispose of it. Reheating should not be done quite frequently.Each time food is reheated, its safety and quality becomes questionable. However, by following certain guidelines reheated meals can be enjoyed without concerns about food safety.Do not Reheat These Foods More Than OnceIt is safe to reheat most foods more than once under suitable temperature and storage conditions. However, there are certain foods that should not be reheated more than once. This is because frequent reheating, even if done properly, negatively affects their taste, quality, texture and overall safety. Examples of foods that should not be reheated more than once include:PrawnsFishMilkCheeseCustardCooked RiceGnocchiSoupsThe Safe Method to Reheat Food LeftoversThe safe method to reheat food leftovers requires knowledge about the correct reheating temperature, refrigeration conditions and suitable reheating equipment.Safe Reheating Temperature and Duration for Food LeftoversIt is preferable to reheat food at 165�F (74�C) for a duration of at least 2 minutes.�Achieving proper internal temperature of food to kill any bacterial growth that may have occurred during storage is the most important aspect of reheating food safely.�Food safety guidelines in England require reheated food to reach an internal temperature of at least 70 �C (158�F). In Scotland, a minimum reheating temperature of at least 82 �C (180�F) is allowed.Safe Fridge and Freezer Storage for Food LeftoversStored food must be kept refrigerated at below 5�C and frozen between 0�C and -18�C. Leftover cooked food can be stored safely for up to 3 to 4 days, with some exceptions. Any unconsumed portions of food must be stored within 2 hours.Proper refrigeration and freezer storage of food can help preserve food to maintain its safety and hygiene.Safe Reheating Equipment for Food LeftoversFood should be reheated to the ideal internal temperature of 165�F (74�C) on air fryers, stovetops, microwave ovens and conventional ovens. It is important to note that slow heating devices are not recommended for reheating leftovers.Reheating Food in an Air fryerAir fryers are a recent invention in the world of cooking that serve dual purposes of cooking and reheating. While reheating food in an air fryer, set the temperature to 350�F (175�C) and reheat food for a few minutes. Check that its internal temperature reaches 165�F (74�C). Allow frequent stirring for proper heating. Air fryers provide convenience for preserving flavour and moisture content of your reheated food.Reheating Food in a Slow CookerSlow heating devices, such as a slow cooker, are not recommended for reheating leftovers. It carries the risk of food remaining over-exposed to temperatures in the danger zone, between 40 �F and 140 �F. The danger zone temperature� increases the growth rate of food bacteria.Reheating Food in Conventional Ovens, Microwave Ovens and StovetopsConventional ovens reheat food evenly but may take longer than other heating devices. Reheating in microwave ovens requires periodic stirring for even heating. Accurate temperature control can be achieved with stovetops but may demand our undivided attention.Defrosting and Reheating Frozen FoodCompletely defrost frozen food before reheating, by placing it from the freezer to the fridge, kept at a temperature range of 0�C- 4�C. It is not recommended to defrost food at room temperature or in a microwave. This is to avoid exposure to undesirable temperatures that promote bacterial growth in food.Reheating Frozen Food TwiceOnce frozen food has been thawed, it is recommended to reheat it only once to prevent the risks of spoilage and microbial contamination. However, frozen food can be reheated more than once provided that it is thoroughly heated to an internal temperature of 165�F (74�C) to completely destroy harmful bacteria.For more information, visit our blog article, �Cooking Raw Frozen Food Without Defrosting.�Probe Thermometer to Check Food TemperatureThe reading on the thermometer will indicate whether the food has undergone any contamination or spoilage due to bacterial growth. Check temperature using an appropriate metal stem probe thermometer to detect microbial spoilage in food.Safe Reheating of Food for ChildrenThe NHS suggests that reheating cooked food for a child should only be done once. Microwaved food should be stirred properly to avoid any air pockets before feeding the baby. While reheating, food must be hot and cooled before serving.Refrigerating Food LeftoversReheated food must be allowed to cool properly before storage. For rapid cooling, food can be placed in an ice bath and chilled before placing it in the fridge.Common Risks of Reheating FoodCommon risks concerned with reheating food include inappropriate temperatures leading to uneven heating and if the food has been stored at room temperature for a prolonged period of time. These risks lead to food poisoning, anti-palatability and consumer dissatisfaction.Inappropriate Temperatures and �Hot Spots�If food is reheated at an incorrect temperature, certain parts of food reach higher temperatures than others. This creates �hotspots� that act as breeding grounds for food pathogens. Pockets of hot and cold portions of food can also lead to an unsatisfactory taste and lack of appetite for the meal.Prolonged Storage at Room temperatureThe chances of bacterial contamination increase if food is stored at room temperature for a prolonged period of time. At room temperature, food is susceptible to �Danger Zone� temperatures between 40�F (4�C) and 140�F (60�C). At these temperatures, bacteria thrive and multiply, leading to food spoilage.Food poisoning and Consumer Health ImpactsA negative consequence of consuming unsafe reheated food is food poisoning, due to entry of pathogens such as Campylobacter and Salmonella into the human body. Common symptoms of food poisoning include nausea, vomiting, diarrhoea, and in severe cases, hospitalisation or even death.Impact on Commercial Food ProductsFood reheating and storage protocols are important to uphold the reputation and popularity of a food business. If customers face health concerns due to low food quality, the demand for the food product can decline. This can result in financial losses for the food company. For consumer loyalty and trust, safe food reheating and storage guidelines should be followed.Common Mistakes in Reheating FoodSeveral common mistakes can compromise the safety and quality of reheated food. These include use of plastic or metal containers, reheating food at incorrect temperatures, and uneven heating.Use of Plastic or Metal ContainersPlastic containers, when exposed to high temperatures, can pass on undesirable chemicals to food. Sparking can occur on uneven heating with metal containers. It is preferable to use ceramic or microwave safe-glass containers to heat food evenly, to avoid chemical leaching.Reheating Food at Inappropriate TemperaturesThe appropriate temperature to reheat food is at least 165�F (74�C) to destroy bacterial growth. If reheated at an inappropriate temperature, any bacteria present in food will not be completely destroyed. This increases the risk of food poisoning. It is recommended to use a food thermometer to make sure that food has achieved desirable reheating temperatures.Lack of Stirring for Even HeatingWhen one does not stir food properly while reheating, some portion of food may become burnt while the rest would be left under-heated. This reduces palatability and promotes microbial growth in food. Constant stirring while reheating helps distribute heat evenly throughout the food, confirming food hygiene. .second-cta-block .main-heading { font-weight: bold; font-size: 22px; } .second-cta-block .book-now { background: #DF3D52; color: #FFFFFF !important; border-radius: 8px; } .second-cta-block .second-heading { font-size: 17px; } .second-cta-block .card { border: 0 !important; } .second-cta-block .card-body { border: 1px solid #909090; box-shadow: rgba(0, 0, 0, 0.16) 0px 1px 4px; border-top-right-radius: 100px; border-bottom-right-radius: 100px; background: #fdf9ee; } .second-cta-block .image-wrapper { height: 330px; position: absolute; right: -60px; top: calc(50% - 210px); /* Center the image vertically */ } .second-cta-block .image-wrapper img { height: 100%; } .second-cta-block .trustpilot-widget { width: 256px; } .cta-heading-section { width: 75%; } @media screen and (max-width:991px) { .second-cta-block { padding-top: 100px; } .second-cta-block .card-body { border: 1px solid #909090; box-shadow: rgba(0, 0, 0, 0.16) 0px 1px 4px; border-radius: 19px; border-radius: 14px; background: #fdf9ee; } .cta-heading-section { width: 100%; padding-top: 50px; } .second-cta-block .image-wrapper { height: 270px; right: 0; position: absolute; left: calc(50% - 90px); top: calc(50% - 315px); } } Get Online Food Safety Courses Food Hygiene And Safety Check the Course Rated Excellent on major review sites When to Discard Reheated Food?Sometimes bacterial activity can cause contamination in food that undergoes proper reheating. Unusual flavours, odours and texture are signs of discarding the reheated food and it�s best not to eat it.�OdourThe most prominent sign of spoilage is foul and unusual odour which could imply chemical changes in food due to bacterial contamination.FlavourUncharacteristic or sour flavour of food that is different from its original taste is another sign of food spoilage due to bacterial activity.TextureIf reheated food has become slimy or semi solid in nature, indicating unusual consistency of food, the reheated food must be discarded immediately.It is best to practise vigilance when examining reheated food before eating it.
