On Monday, Cadbury officially informed the FSA of the possible contamination of the seven products.
The 250g Dairy Milk Turkish, Dairy Milk Caramel and Dairy Milk Mint bars, the Dairy Milk 8 chunk and the 1kg Dairy Milk bar are among products affected.
The 105g Dairy Milk Buttons Easter Egg and the Freddo bar were also affected.
'Precautionary measure'
Cadbury's European president Matthew Shattock told BBC Radio 4's Today programme the recall decision was made after the FSA revealed there had been an increase in the number of salmonella cases this year.
"We decided to conduct a precautionary recall to reassure our consumers and the public at large to minimise any confusion as to the quality of our products," he said.
Salmonella is a common cause of food poisoning but the montevideo strain is very rare.
There have been 45 cases in the UK in the last four months, compared with just 12 in the same period last year.
But a Health Agency spokeswoman stressed that at the moment there was no evidence for a link between the increase in cases and the Cadbury recall.
