Everyone working in the food and drink industry has a responsibility for food safety and for preventing contamination. Part of this involves preventing and managing chemical hazards in food, as these can cause serious long-term harm if consumed. In this article, we\u2019ll explain what chemical hazards in food are, give some examples of where chemical hazards can be found and provide some top tips for preventing chemical contamination in your workplace.<\/p>\n\n\n\n

\n\n\n\n

What are Chemical Hazards in Food?<\/h2>\n\n\n\n

Chemical hazards in food are any type of chemical substance present in a food or drink product that can cause immediate or long-term harm to consumers. It may be that the chemicals are added intentionally but in hazardous amounts, such as additives and preservatives, or it could be a case of chemical contamination from toxins in the environment, unsafe food processes or even malicious intent.<\/p>\n\n\n

\n
\"Using<\/figure><\/div>\n\n\n

Chemical contaminants can enter food products at any time during the food production process and at any point in the food chain. For example, chemical hazards may come from the environment, such as pollution, incinerators, contaminated land and water, plant diseases or in animal feed. Chemicals can also enter the food chain during processing and production, such as acrylamide during cooking, mycotoxins in storage or misuse of cleaning chemicals.<\/p>\n\n\n\n

Alongside chemical hazards in food, the other types of hazards that make foods unsafe to eat are physical hazards<\/a> and microbiological hazards, which cause food poisoning<\/a>.<\/p>\n\n\n\n

\n\n\n\n

Examples of Chemical Hazards in Food<\/h2>\n\n\n\n

Chemical contaminants can enter food products at any point in their production, from farming and manufacturing to cooking and cleaning. Examples of chemical hazards in food include:<\/p>\n\n\n\n

Mycotoxins<\/h4>\n\n\n\n

These are naturally-occurring chemicals produced by certain types of moulds and, when eaten in large amounts, can cause serious harm to consumers. The most harmful type is aflatoxins, which have the potential to cause cancer and\/or problems with digestion, reproduction or the immune system.<\/p>\n\n\n\n

In warm and damp conditions, mycotoxins can grow on all types of crops and foods, but particularly dried foods such as cereals, spices, nuts, dried fruit and coffee. Because mycotoxins are naturally-occurring, it\u2019s impossible to remove them from foods completely. Instead, food safety controls based on HACCP should be used to reduce their levels to as low as possible.<\/p>\n\n\n

\n
\"Identifying<\/figure><\/div>\n\n\n

Organic Environmental Pollutants<\/h4>\n\n\n\n

Also known as persistent organic pollutants (POPs), organic pollutants are chemicals that enter food from the environment where it\u2019s grown or reared. At high levels, these types of chemicals can be harmful to animals and fish as well as humans.<\/p>\n\n\n\n

Examples of environmental chemical hazards are pesticides, herbicides, fungicides and fertilisers used in farming, heavy metals such as lead, mercury and cyanide found in the earth and dioxins, often originating from animal feed.<\/p>\n\n\n\n

Acrylamide<\/h4>\n\n\n\n

Acrylamide is a naturally-occurring by-product created when starchy, carbohydrate-rich foods are fried, roasted, baked, grilled or toasted at temperatures of 120 \u00b0C and above. It\u2019s impossible to avoid acrylamide completely but high levels have been proven to be carcinogenic.<\/p>\n\n\n\n

Foods that are most susceptible to developing high levels of acrylamide during the cooking process include potato chips and crisps, bread, breakfast cereals, biscuits and crackers. Find out more about acrylamide with our Short Guide to Acrylamide in Food<\/a>.<\/p>\n\n\n\n

Cleaning Chemicals<\/h4>\n\n\n\n

It\u2019s easy to see how mishandled or misused cleaning chemicals can end up in food products if a work surface or tool isn\u2019t adequately cleaned and rinsed or if they\u2019re not stored safely. Sanitisers, disinfectants and bleaches are all incredibly harmful to health if they end up in food and drink intended for consumption.<\/p>\n\n\n

\n
\"Chemical<\/figure><\/div>\n\n\n

Other areas where chemicals can enter food are during manufacturing, where lubricants and oils from the machinery in factories can contaminate products, as well as paints and varnishes being used in the food production area without appropriate food safety controls in place.<\/p>\n\n\n\n

Chemical Food Crime<\/h4>\n\n\n\n

In some cases, chemical contaminants are intentionally added to foods as a result of food crime. The Food Standards Agency has reported on cases in the past where food has been deliberately contaminated with the intent of harming the general public.<\/p>\n\n\n\n

Food crime using chemicals is rare but is still an important safety consideration, particularly for food manufacturers. Find out more about Whistleblowing on Food Crime<\/a> in our article.<\/p>\n\n\n\n

How to Prevent Chemical Hazards in Food<\/h2>\n\n\n\n

In order to prevent the contamination of chemical hazards in food, food business operators must have a food safety management system – a HACCP plan – in place to ensure all food safety risks have been identified and managed, including chemical hazards.
