Help Rather Than Hype to Those with Food Allergy
When it comes to food allergies and intolerance, the advice available to the public ranges from the dependable to the downright dangerous. Recognising the need to ensure that the public receive consistent and reliable advice, The British Dietetic Association (BDA) has collaborated with the Food Standards Agency and five other allergy and nutrition organisations (Allergy UK, the Anaphylaxis Campaign, the British Nutrition Foundation, Coeliac UK and Foods Matter) on a just published advice leaflet for people who have been newly diagnosed with a food allergy.
The leaflet, ‘Buying food when you have a food allergy or intolerance’, guides people with a food allergy or intolerance, including coeliac disease, through the steps to remember when buying food and when eating out. The topics covered include checking the label on pre- packed food; what to look out for when foods aren't pre-packed; talking to restaurant staff about your allergy; what to watch out for when using self-service
restaurants.The leaflet also reassures people that there is no need to worry that being unable to eat a particular food will harm health and reminds them that it is the overall balance of their diet that matters. Dietitian Heidi Ball who contributed to the leaflet said ‘If you can’t eat certain foods it’s a good idea to choose other foods you can eat to give you the nutrients you need. For example if you are cutting out dairy, you’ll need to make sure you include other sources of calcium. Remember, don’t cut major food groups out of your diet without medical advice.’

Media for Monitoring Fungi in Foods
Identifying Staphylococci in Foods within 24 Hours
Oxoid announced the launch of Brilliance™ Staph 24 Agar - a selective and diagnostic chromogenic medium for the isolation and enumeration of coagulase-positive staphylococci (CPS) in foods, within 24 hours. Staphylococci are found in a broad range of foods, including meat, dairy, bakery and ready-to-eat products. EU regulations on acceptable limits of staphylococci in cheese, milk powder and shellfish are in place; with levels exceeding 1x105CFU/g considered as dangerous. Food producers therefore need to demonstrate that their products contain levels lower than this concentration. Foods that require extensive handling, preparation or are kept at slightly elevated temperatures after manufacture are commonly implicated in staphylococcal food poisoning.
Oxoid Brilliance Staph 24 Agar allows the isolation and enumeration of CPS 24 hours earlier than with traditional media (such as Baird- Parker Egg Yolk Tellurite Agar) which take at least 48 hours for a result. On Brilliance Staph 24 Agar, CPS will grow as dark blue colonies on a clear agar background, allowing rapid, easy identification and enumeration within 24 hours.
Brilliance Staph 24 Agar detects coagulase-positive staphylococci, including pathogenic coagulase-positive, non-aureus staphylococci, such as S. intermedius. It also -prevents growth of nontarget organisms, therefore, eliminating extensive confirmatory testing and miscalculation of cell counts. The Oxoid Brilliance Staph 24 Agar method has been validated and approved by MicroVal according to the ISO 16140 standard against the reference method ISO 6888:1999-Horizontal method for the enumeration of coagulase-positive staphylococci (Staphylococcus aureus and other species) - Part 1: Technique using Baird-Parker Agar medium for meat, dairy, seafood, bakery products and composite food.

Fungal spoilage of food remains an important economic issue, and at the same time the production of mycotoxins by some of the organisms responsible can also present a health challenge.
Monitoring and subsequent disposal of contaminated food therefore has an important role. Designed for this task, Lab M’s range of microbiological culture media includes both Rose Bengal Chloramphenicol Agar and Dermatophyte Test Medium.
Lab M’s Dermatophyte Test Medium aids differentiation between saprophytic and environmental fungi. Used alongside Rose Bengal Chloramphenicol Agar, a selective medium for the enumeration of yeasts and moulds in foods, it is proving to be an important part of any programme aiming to comprehensively monitor food products and processing.
As part of Lab M’s extensive range of microbiological culture media, the company offers a wide variety of products that are used primarily in food industry applications.
