Which food probably contains the MOST bacteria?

Raw chicken is known to be a potential source of bacterial contamination, including pathogens like Salmonella and Campylobacter. Freezing the chicken does not kill these bacteria, but it can help slow down their growth. However, once the chicken is thawed or cooked improperly, the bacteria can multiply and pose a risk of foodborne illness if consumed.
While a stale slice of bread or an opened jar of mayonnaise may also harbor some bacteria, they are generally less likely to contain high levels of harmful bacteria compared to raw chicken. Proper storage and handling of food, including thorough cooking of chicken to safe internal temperatures, are crucial in reducing the risk of bacterial contamination and foodborne illnesses.
