The Agriculture & Food Laboratory has certain testing
supplies for sale. These include:
Food fraud is a collective term used to encompass the
deliberate and intentional substitution, addition, tampering, or
misrepresentation of food, food ingredients, or food packaging; or false or
misleading statements made about a product for economic gain (Spink and Moyer,
2011a). The types of fraud include adulteration, tampering, overrun, theft,
diversion, simulation, and counterfeiting (Spink and Moyer, 2011b).
Food Fraud is not a new phenomenon,
but is gaining attention in recent years due to the number of cases and the
costs associated with the fraud. Recent
food fraud cases include horse meat scandals and cases related to the
intentional mislabelling of fish in stores.
Some of the common foods involved in adulteration include olive oil,
milk, honey, saffron, coffee, tea, fish and meat.
The adulteration of meat products with undeclared animal
species can result in recalls of the products and reduce consumer confidence on
well established product brands.
Laboratory testing is used to determine the species composition of
processed meat products to assess their authenticity.
The Agriculture & Food Laboratory offers analytical
tests for the presence of various animal species (e.g. beef, pork, ruminant) in
food or feed samples. PCR (Polymerase
Chain Reaction) methods are used to detect animal species-specific DNA while
ELISA (Enzyme-Linked ImmunoSorbent Assay) methods are applied in the detection
of species-specific proteins in food and feed samples. The Agriculture &
Food Laboratory is accredited by SCC to ISO/IEC 17025 for the “Detection of
Residual Bovine, Ruminant, Porcine, Animal and Rice DNA in Feed and Food
Samples” as listed on our scope of Accreditation.
In order to meet your operational needs, we offer same day
results for rush services or 2-3 business days for standard services. Use these results to gauge control measures used
to prevent undeclared materials in food operations, to support export
activities and other uses.
*cooked meat only.
Our laboratory also offers
analytical testing for the identification of unknown animal or plant
species. Identification is done using DNA
Verticillium longisporum, a fungal pathogen considered a major disease of oilseed rape in Europe, has been discovered in canola in Manitoba. This soil borne fungus infects through the roots of canola plants and then grows into the xylem throughout vegetative parts of the plant. The xylem, which transports water, becomes clogged resulting in wilting and often death of the plant. The fungus produces microsclerotia that survive in plant debris in soil for many years.
Growing concerns about food authenticity and the increasing
demands in the Halal markets are requiring that certifying agencies and food
producers ensure the integrity of their brands. Detection of porcine materials
in these foods is a key factor in verification of Halal.
Porcine DNA residue testing services at the University of
Guelph’s Agriculture and Food Laboratory are available for verification that
Halal food products are produced without pork. The Porcine DNA residue test is
ISO 17025 accredited to ensure food manufacturers that the test results are
generated through a testing process recognized by international quality

The University of Guelph, Agriculture & Food Laboratory (AFL) tests both finished food products and raw ingredients for the presence of staphylococcal enterotoxins A, B, C, D, and E.
Turnaround times for test results are typically within 5-10 business days. However, clients requiring rush analysis should contact our client services at email@example.com or 519-767-6299 to discuss the necessary testing details, terms and pricing.
Foods that are frequently involved in staphylococcal food intoxication include:
· meat and meat products,
· poultry and egg products,
· salads such as egg, tuna, chicken, potato, and macaroni
· bakery products such as cream-filled pastries, cream pies, and éclairs
· milk and dairy products
Staphylococcus aureus produces heat stable proteins that behave as enterotoxins. Staphylococcal food intoxication is the name of the condition caused by consuming these enterotoxins
Common symptoms of staphylococcal food intoxication are nausea, retching, abdominal cramping, and vomiting. Some individuals may not always demonstrate all the symptoms associated with the illness. In more severe cases, headache, muscle cramping, and transient changes in blood pressure and pulse rate may occur. Recovery generally takes two days. The onset of symptoms in staphylococcal food intoxication can be as rapid as 30 minutes and often occurs within 2-4 hours. Victims of staphylococcal food intoxication are usually quick to identify the contaminated food due to the rapid onset of their symptoms.
We offer the following methods:
MFLP-65: Detection of Staphylococcal Enterotoxins in Food Products Using the VIDAS® Staph Enterotoxin II (SET2), an ELFA (Enzyme Linked Fluorescent Assay) Technique
MFLP-69: Detection of Enterotoxins Produced by Staphylococcus aureus (Ridascreen SET A, B, C, D, E Enzyme Immunoassay)
Food processors may want to consider proactively implementing staphylococcal enterotoxin testing as a regular component in their quality control program. These companies should contact the Agriculture and Food Laboratory at firstname.lastname@example.org or 519-767-6299.

Currently, neonicotinoids, a relatively new class of insecticide, are in wide use globally. These more water soluble compounds are taken up by plants to provide protection from insects.
In 2011-12 the AFL established a method for testing this class of insecticide in a number of bee related products (i.e. honey, pollen, beeswax), as well as bees themselves, to help determine the extent of exposure which may be occurring. We also test a range of environmental samples where bees and other insects may be additionally exposed to these compounds such as water, soil and vegetation. In addition, we can screen for these pesticides in fruits, vegetables, animal tissues and treated seeds Please call for further information.

DNA fingerprinting and beyond
Traditionally, identification of microorganisms is based on physical characteristics such as growth appearance, microscopic appearance, and biochemical reactions. DNA sequencing, based on genetic codes contained in microorganisms, has now become the method of choice for microbial species identification. The Agriculture and Food Laboratory (AFL) also utilizes the Next Generation Sequencing (NGS) technologies to analyze microbial communities in very complex samples. Hundreds of different genus and species of microorganisms, or a "microbial profile", which would otherwise be very difficult to analyze, can now be identified simultaneously from a single sample in a single experiment. The AFL also plans to develop new methods using these NGS technologies for food safety diagnostics in near future.

Extraneous Material and Filth Testing in Food
AFL microscopists, diagnosticians, and analysts use Health Canada and/or AOAC Official Methods to test for extraneous material as well as light and heavy filth in food.
Major contaminants involved in food product recalls include Metal and Glass. Further testing on metal and glass can be performed to assist in identifying the source of contamination if necessary.
Another major contaminant in food involves insects or insect fragments, as well as their eggs, larvae, and excreta. The University of Guelph has one of the largest insect collections in Canada. Our entomologists can identify the insect and provide background information on typical sources and treatments if requested.
Additional extraneous material and filth contaminants include hair, fibres, and plastic. Our vast experience with foreign material identification has equipped us in determining virtually every possible contamination source before and after processing of foods.

Microbial (bacteria, yeasts and fungi) Species Identification
Sound Science and Service:
Traditionally, identification of microorganisms is based on phenotypic characteristics such as morphology, Gram staining and biochemical reactions. The present status of the taxonomy of microbial species in Bergey's Manual of Systematic Bacteriology (2nd ed) is mainly based on comparative genetic analysis of the nucleotide sequences of the small subunit ribosomal RNA that is contained in all microorganisms. DNA sequence analysis is widely considered to be the best genotypic method for microbial species identification.
At Laboratory Services, University of Guelph, we conduct routine identification of "unknown" samples (bacteria, yeasts and fungi) using DNA from the microorganisms. You will receive objective, reproducible and cost-effective results rapidly without relying on growth, biochemical reaction and prior knowledge of the organism (e.g. Gram stain).
