Challenge testing

Microbiological challenge testing

Just because an organism is in a product, it does not mean that it poses a problem or will compromise product shelf–life. Most pathogens and spoilage organisms will need to survive and grow in order to reach levels at which the food is compromised.

Microbiological challenge testing is a practical study to determine the behaviour of relevant organisms if they should be present in a product. It involves deliberate inoculation of the product with relevant organisms. The product is then stored and tested for these organisms during shelf life.

Campden BRI offers expert advice and guidance on challenge testing shelf life determination and can undertake challenge tests with a wide range of organisms including Escherichia coli O157 and Clostridium botulinum.
