The Interagency Food Safety Analytics Collaboration (IFSAC) are out with their attribution (what foods are likely to be contaminated) for 2018.  Here is the full report: P19-2018-report-TriAgency-508

Here is the Summary:

Salmonella illnesses came from a wide variety of foods. More than 75% of Salmonella illnesses were attributed to seven food categories: Chicken, Seeded Vegetables (such as tomatoes), Pork, Fruits, Other Produce (such as nuts), Eggs and Turkey.

E. coli O157 illnesses were most often linked to Vegetable Row Crops (such as leafy greens) and Beef. Over 75% of illnesses were linked to these two categories.

Listeria monocytogenes illnesses were most often linked to Dairy products and Fruits. More than 75% of illnesses were attributed to these two categories, but the rarity of Listeria monocytogenes outbreaks makes these estimates less reliable than those for other pathogens.

Non-Dairy Campylobacter illnesses were most often linked to Chicken. Over 75% of non-Dairy foodborne illnesses were attributed to Chicken, Other Seafood (such as shellfish), and Turkey, with Campylobacter illnesses most often linked to Chicken. An attribution percentage for Dairy is not included because, among other reasons, most foodborne Campylobacter outbreaks were associated with unpasteurized milk, which is not widely consumed, and we think these over-represent Dairy as a source of illness caused by Campylobacter. Removing Dairy illnesses from the calculations highlights important sources of illness from widely consumed foods, such as Chicken.
