The Food section of the IAS Laboratory specialises in the analyses of nutritional and contaminant content of South Pacific foods, data on which can be used for nutritional labeling. The combination of these skills as well as in sampling and food technology are used to explore new product developments for community initiatives and trade. The facility has generated nutrient data for 150 foods and revised the Pacific Island Food Composition Tables which is necessary for nutrition planning, agriculture policy and trade. Through a larger project with the UN Food and Agriculture Organisation, it has developed a capacity to analyse all major food contaminants common in the region which are important for trade and health purposes and to monitor the Food Act and Environmental Management Act. These include heavy metals, histamine and certain pesticides types.

Fish & Fish Products Testing for the European Market
For exporting purposes to the European Union (EU), the IAS Laboratory Services offers accredited tests for fish & fish products such as Histamine in Fish, Lead, Cadmium & Mercury in Fish, coagulase positive Staphylococci in fish and other microbiological tests listed above under “Nutritional Information Panels & Food Safety Monitoring“. European Union assessors have over the years visited and assessed the IAS Laboratory for competence in analysis of fish & fish products exported to the EU. As a result IAS Laboratory Services is a designated EU laboratory for analysing fish & fish products destined for the EU in the South West Pacific.
Nutritional Information Panels & Food Safety
A Nutrition Information Panel (NIP) is a table that lists the average quantities of seven key components of food and is required on most packaged foods. The quantities are given per serving and per 100 grams (g) or milliliters (mL). NIPs can be used to compare foods, allowing consumers to choose foods which are lower in fat, saturated fat, sugar and sodium. Our analysis provides accurate information about the nutrient composition of a product. Testing for NIPs includes:
- Sodium
- Ash
- Carbohydrate (by difference)
- Dietary fibre (soluble, insoluble and total)
- Energy
- Fat
- Moisture
- Protein
- Total sugars
- Saturated fat
- Cholesterol
- Trans fatty acids
Mineral Analysis
Testing for minerals includes:
- Toxic / heavy metals (Lead, Mercury, Cadmium)
- Trace elements (chromium)
- Other minerals (sodium, potassium, calcium & iron)
Vitamin Analysis
Testing for Vitamin in Food, Dairy, Raw material and premix includes:
- Vitamin A – retinol & carotenes
- Vitamin B – thiamine and riboflavin
- Vitamin C – ascorbic acid
Food Safety Monitoring
Food for human consumption must be safe and does not pose any risks to health. For this reason, food manufacturers are required to monitor and test their products for micro-organisms that may have potential to pose a risk to humans. The testing criteria are largely specified by overseas markets that the products are being exported to and also to fulfill domestic market regulations. Some of the accredited food safety tests done by the IAS Laboratory Services are:
- Aerobic Plate Count
- Coliforms (Total & Faecal)
- Yeasts and Moulds
- Escherichia coli
- Salmonella species
- Campylobacter jejuni
Bacillus cereus (presumptive)
- Enterobacteriaceae
- Staphylococcus aureus
- Salmonella
Non-accredited tests but for which quality control checks are applied are:
- Listeria species
- Listeria monocytogenes
- Vibrio parahaemolyticus
Kava and kava products testing
Kava testing for exporting purposes is also available. Available tests are lactones and moisture
