Policies & Practices

How We Create Healthy Kids Lunches

When it comes to making Healthy Kids Lunches, we make sure we meet national standards. 
Here is how we make sure we’re only serving the highest quality meals to children:

Diet & Allergy Restrictions

Our School Catering Program is extra mindful of students with food allergies

Our software helps us enter data referring to dietary restrictions for the student population. This helps us navigate wholesome solutions when meal planning to create the best Healthy Kids Lunches possible. 

We adhere to such dietary restrictions as lactose/dairy-free, gluten-free, and diabetic.

Through our software, we can provide nutritional information to school nurses and parents to ensure the safety of the child.

HACCP and Food Safety

Not only are we NSLP compliant, we are also HACCP Certified

At Nutrition ONE we are constantly educating and improving our regulations as the industry grows. 

We employ a food safety monitor to check daily systems and tests us to make sure we are compliant with local county environmental agencies. 

We require all our employees to be Serve Safe certified, as well as perform daily food temperature checks and complete proper labels. 

USDA Compliance

USDA NSLP compliance standards dictate what makes school lunch healthy

We use web-based software to stay compliant with FDA and USDA regulations. The software monitors nutritional information to ensure we maintain balance in our school lunch menus. 

Our nutritionists use Nutrikids and Mosaic software to create recipes and order food based on availability. We also use this software for our auditing process. 

We use Mosaic software to stay compliant with USDA School Lunch guidelines
We use Nutrikids software to stay compliant with NSLP guidelines
