When the Food Safety Modernization Act (FSMA) was signed in 2011, the importance of growing, harvesting and processing of fruits and vegetables was recognized as the start of food safety for the familiar term of farm-to-fork.

Intentional adulteration, commonly called food defense, is the deliberate addition to an ingredient or food of a hazard to cause illness or injury which makes the food adulterated.

Pre-season football has begun, and the tourists have descended upon my hometown of Green Bay, Wisconsin. Each year there is a bit of quiet during the months of May and June – after the NFL draft […]

Mock Recalls: Highly Encouraged

Let’s spend some time addressing a topic that not one single food manufacturer or distributor enjoys discussing: product recalls. Let’s face it, a product recall could be one of the largest headaches your company has to face, but if completing a smoothly operated and well-organized recall means no consumer gets ill or passes away, it […]

Dry Operations & Recalls

Dry operations are tricky. They are called dry operations not only because the finished product may indeed be dry, but also because water is the enemy of the products. Water creates a greater risk for the pathogen Salmonella in the environment. When I think of dry operations, I think of dry ingredients: powders, spices, gums, […]
