Meat, chicken, beans and wheat, important food items in family expenditure and in periods of smaller supply, recorded major increases in the month and were the main contributors to the acceleration of IPCA-15 from September to October. That led to a change of 1.70% in the food and beverages group, higher than the previous rate of 0.30%. As in September, meat was the leading item in October: with an increase of 4.93%, it contributed with 0.11 percentage points to the month index. Consumers also started to pay more for chicken (5.69%), spaghetti (2.68%), French rolls (2.53%) and cookies (1.51%), though carioca beans reached the highest cost rate, 24.56%.

In order to estimate IPCA-15, prices were collected from September 14 to October 13 and compared with those obtained from August 14 to September 13 of 2010. The indicator refers to families with 1-to-40-minimum-wage income and encompasses the metropolitan regions of Rio de Janeiro, Porto Alegre, Belo Horizonte, Recife, São Paulo, Belém, Fortaleza, Salvador and Curitiba, as well as Brasília and Goiânia. The method used for this indicator is the same as the one used for IPCA; except for the different period of collection of prices.
