Harmful chemicals in food, like pesticides, fall into the category of chemical hazards. Chemical hazards are defined as substances that can cause health issues when ingested, inhaled, or come into contact with skin. These can include a wide range of substances such as pesticides, food additives, heavy metals, and other contaminants. The presence of these chemicals can result in various health problems, from short-term symptoms like nausea to long-term effects such as chronic illnesses or even poisoning.
This categorization is critical in food safety practices because it helps food handlers and safety officials identify potential risks and implement proper management strategies to minimize exposure. Understanding the nature of chemical hazards allows for better monitoring during food production, processing, and preparation to ensure consumer safety. In contrast, biological hazards refer to pathogens such as bacteria and viruses, while physical hazards involve foreign objects that can cause injury. Food allergens are specific proteins that trigger allergic reactions in sensitive individuals.
