Food Borne Pathogens in Refrigerated Bakery Merchandisers
The UV and visible spectrum radiation emitted by most bakery display case lighting accelerates the growth of food borne pathogens in decorative cakes containing eggs and dairy products, even if the cakes are refrigerated. If the lighting source emits heat, as most bakery display case lamps do, desserts made with eggs are even more likely to cause food poisoning. Promolux lamps emit lower levels of UV radiation, reducing this risk.

LOL, my paramedic training never covered UV radiation or foodborne pathogens. I must call the college and complain!

Can you provide a link to the entire article or provide the source of the article?

I found your quote - on the Promolux lamps website - a commercial website that is hawking their product.

I guess this information is of value if you have a merchandising case and are shopping for new fluorescent bulbs for it. ??
