- This unit provides a detailed discussion of the chemical and physical aspects of food contamination. The focus is on sources of contamination occurring naturally in food, formed during processing or production (veterinary drug residues, pesticides) of food, introduced as food additives or as a consequence of migration from third party sources (taints, packaging, environmental chemicals such as dioxins and PCBs). Safety of genetically engineered foods, risk assessment, food safety policy, management procedures and laboratory techniques are discussed. Allergens and intentional food contamination are also explored. Chemical techniques used to detect, analyse and characterise contaminants are explored in detail. Safety policies and management procedures are introduced.
- Students are able to (1) define different types of food contaminants and understand their origins; (2) understand the major classes of drugs used in animal farming and pesticides used in agriculture; (3) describe the physical chemistry background of toxicant formation in food processing; (4) define and identify external sources of contaminants such as packaging and inks; (5) attain good working knowledge of chemical techniques used to detect, analyse and characterise contaminants; (6) recognise contaminant issues and recommend a method of analysis; (7) understand the use, safety and toxicology of common food additives; (8) differentiate food allergy and food sensitivity; and (9) explore future issues in food contamination.
- Typically this unit is assessed in the following ways: (1) laboratory reports (30 per cent); (2) an assignment/presentation (20 per cent); (3) case study discussion (10 per cent); and (4) a two-hour competency-based examination (40 per cent). Further information is available in the unit outline.
Supplementary assessment is not available in this unit.

- The availability of units in Semester 1, 2, etc. was correct at the time of publication but may be subject to change.
- All students are responsible for identifying when they need assistance to improve their academic learning, research, English language and numeracy skills; seeking out the services and resources available to help them; and applying what they learn. Students are encouraged to register for free online support through GETSmart; to help themselves to the extensive range of resources on UWA's STUDYSmarter website; and to participate in WRITESmart and (ma+hs)Smart drop-ins and workshops.
- Books and other material wherever listed may be subject to change. Book lists relating to 'Preliminary reading', 'Recommended reading' and 'Textbooks' are, in most cases, available at the University Co-operative Bookshop (from early January) and appropriate administrative offices for students to consult. Where texts are listed in the unit description above, an asterisk (*) indicates that the book is available in paperback.
