effect 1 December 2015. Research has shown that the new labels may influence consumer choices, but primarily if it provides unexpected information and that health-conscious consumers are resistant to changing behaviors based on menu labeling Fast food restaurants are expected by the ERS to do better under the new menu labeling than full-service restaurants as full-service restaurants tend to offer much more calorie-dense foods, with 50% of fast food meals being between 400 and 800 calories and less than 20% above 1000 calories, in contrast, full-service restaurants 20% of meals are above 1,400 calories. When consumers are aware of the calorie counts at full-service restaurants 20% choose lower calorie options and consumers also reduce their calorie intake over the rest of the day. Eating one meal away from home each week translates to 2 extra pounds each year or a daily increase of 134 calories and a decrease in diet quality by 2 points on the Healthy Eating Index. In addition; the likelihood of contracting a food-borne illness (such as typhoid and hepatitis B, or diseases caused by E. coli, H. pylori, Listeria, Salmonella, and Norovirus) is greatly increased due to food not being kept below or cooked to a temperature of higher than , not washing hands for at least 20 seconds for food handlers or not washing contaminated cutting boards and other kitchen tools in hot water. Types of service Counter service is food ordered by the customer at the counter and either picked up at the counter by the customer or delivered to the table by restaurant staff. It is common in fast food restaurants in the United States, and in pubs and bars in the United Kingdom (see: Table meal). Table service is food ordered by the customer at the table and served to the customer's table by waiters and waitresses, also known as "servers". Table service is common in most restaurants. With table service, the customer generally pays at the end of meal. Various methods of table service can be provided, such as silver service. Food safety The provision of safe food for foodservice specifies the requirements for the design, implementation, and maintenance of prerequisite programmes (PRPs) to assist in controlling food safety hazards in catering. A technical specification is provided as an international standard, ISO/TS 22002-2:2013 Prerequisite programmes on food safety — Part 2: Catering. This technical specification is part of the ISO 22000
