The CDC says signs of illness from salmonella can include diarrhea, fever, and stomach cramps.

"If FSIS had the ability to identify the source of this Salmonella strain, then the agency would immediately recall the items", the agency stated. The outbreak started in November 2017, but wasn't made public until July 2018. The outbreak, which began around November 20th of past year, has sent at least 63 people to the hospital and claimed at least one life. Children under 5, the elderly, and people with weakened immune systems are more likely to have severe illness from contaminated food that could lead to hospitalization.
