Frequently asked questions from our food industry clients.

If you have a specific query that is not answered here please do get in touch, or find out more in the ‘Food Inspection‘ section.

As a general statement we can detect anything which has a reasonable absorption differential to the product in which it is surrounded. Typically the contaminants are objects such as ferrous and non-ferrous metals, glass, stone, bone, shell and certain higher density plastics and rubber compounds.

The size detectable is influenced by the thickness of the product we are inspecting and the homogeneity of that product. For instance if we were inspecting a sachet of milk powder we could detect a stainless steel wire of 0.2mm yet if it were a pack of breakfast cereal then the detectable wire size may increase to 0.8mm.

Our x-ray inspection equipment is suitable for a broad range of food and pharmaceutical packaging types and materials, including cans, glass packaging, foil and composite packaging and even cases of products. The x-ray systems at AIS can be customised to inspect an unlimited list of cartons, boxes, bottles, tubes, sachets and packaging types manufactured using metal.

We can also quickly inspect toys and electrical products within their packaging for missing components or damaged items, as we have the ability to ‘look inside’ without unpacking or disassembling the goods.

X-ray inspection which delivers a dose of less than 0.5 Gy to food products is permitted under EU Directive 1999/2/EC.

The dose received by a product passing through an x-ray system is extremely low, typically for an x-ray linescan system it is less than 0.2 milli-Gy.

Unfortunately not, but we do offer an effective solution as we regularly inspect this type of product.

We have multiple hook up points and a large secure yard which can accommodate 8 to 10 refrigerated trailers. We work directly from the trailers, as each pallet is removed it is temperature monitored throughout the inspection process and then immediately returned to the trailer (or a spare trailer which is then replaced on the next load). This has been found to be the most efficient method and a full trailer can usually be inspected and turned round in a few hours.

Yes we can. If you would like to trial our x-ray inspection service please complete the form here.

HACCP is a way of managing food safety hazards. Food safety management procedures should be based on HACCP principles … what could go wrong and what risks there are to food safety” Food Standards Agency

HACCP is a food safety management system designed to prevent contamination during food production processes, rather than a finished product inspection procedure.

AIS can provide quality and safety assurance when a Critical Control Point has failed; we offer the highest level of inspection and contamination detection performance available and are certified to operate a Quality Management System which complies with the requirements of ISO 9001.

Threat Assessment and Critical Control Point (TACCP) helps food producers identify weak points in their supply chain and processing activities that may be vulnerable to fraud. It then helps the business minimise the chances of such an attack.” Campden BRI

If your business is the unfortunate victim of a threat or attack, AIS is equipped to assist you with product recovery and safety testing. In the event of an incident (subject to it being a foreign body we can detect) we will be able to quickly and confidentially confirm whether your product is safe to go back into the distribution chain.
