Bestselling cookbooks give little useful advice about reducing the risk of foodborne illness, especially in recipes involving meat products, say scientists who found that most of the information in the books are inaccurate and not based on sound science.”Cookbooks aren’t widely viewed as a primary source of food-safety information, but cookbook sales are strong and they’re intended to be instructional,” said Ben Chapman, from the North Carolina State University in the US.

Not all of the temperatures listed were high enough to reduce the risk of foodborne illness. “In other words, very few recipes provided relevant food-safety information, and 34 of those 123 recipes gave readers information that wasn’t safe,” Chapman said.”Put another way, only 89 out of 1,497 recipes gave readers reliable information that they could use to reduce their risk of foodborne illness,” he said.In addition, 99.7 per cent of recipes gave readers “subjective indicators” to determine when a dish was done cooking.None of those indicators were reliable ways to tell if a dish was cooked to a safe temperature.”The most common indicator was cooking time, which appeared in 44 per cent of the recipes,” said Katrina Levine, from NC State’s Department of Agricultural and Human Sciences.”And cooking time is particularly unreliable, because so many factors can affect how long it takes to cook something: the size of the dish being cooked, how cold it was before going into the oven, differences in cooking equipment, and so on,” Levine said.Other common indicators used in the cookbooks included references to the colour or texture of the meat, as well as vague language such as “cook until done.” “This is important because cooking meat, poultry, seafood and eggs to a safe internal temperature kills off pathogens that cause foodborne illness,” Levine said.The study was published in the British Food Journal.
