Some Ritz Cracker products have been voluntarily recalled over fears they could spread salmonella. Mondelez Global – based in Hanover, New Jersey – said it is recalling 16 varieties of Ritz Cracker Sandwiches and Ritz Bits products in the US. ‘Consumers who have these products should not eat them, and should discard any products they may have,’ the firm warned. The products contain whey powder, which its supplier has recalled due to the potential presence of salmonella.

Health officials in the US have previously warned against the consumption of other foods because of unrelated outbreaks across the country.

Raw turkey and cut melon have been blamed for about 150 cases of salmonella, the Centers for Disease Control and Prevention and Food and Drug Administration warned. There have been 90 recorded cases of turkey-linked salmonella in 26 states and 60 melon-linked cases in 23 states.

Kellogg’s Honey Smacks cereal, meanwhile, has been recalled across the country after 100 people fell ill in 33 states.  It is now illegal to sell the cereal.  Flowers Foods announced a recall of Swiss rolls over fears they may be affected by the salmonella outbreak.
