I imagine that they're selling to a market where Healthy Best is among the first UHT milk products available. So they have to explain the advantages of UHT milk in addition to selling their product (and the two of them go together).

UHT = Ultra high temperature; para la esterilización de la leche.

3.11 The Procedures provide for a mandatory certification process, to ensure compliance with health and safety requirements. The certification standards are set out in Methods of Making Sanitation Ratings of Milk Supplies. Dairy processing plants that comply with the certification requirements are deemed to comply with the requirements of any member of the NCIMS, and thus may ship their milk and milk products to NCIMS member states.
3.12 The Interstate Milk Shippers Program relies upon the Grade ''A'' Pasteurized Milk Ordinance (''PMO''),the "model" regulation developed by the Public Health Service of the FDA establishing technical standards for fluid milk, milk products and UHT milk, and related technical documents referred to in the Procedures Manual for sanitary standards, requirements and procedures it follows to ensure the safety and wholesomeness of Grade ''A'' milk and milk products.6

The long-term solution is recognition of equivalence in our countries' technical regulatory requirements
pursuant to FTA Article 708.1.a. Canada will request, therefore, that the FTA working group on dairy,
fruit, vegetable and egg inspection determine the equivalence of Québec's milk standards and the PMO.
...
Before this recognition is established, however, the only practical way to avoid a serious disruption in our long-standing trade with Puerto Rico may be to have the Canadian milk certified as meeting the requirements of the PMO. I understand that Section 11 of the PMO permits inspection of milk products from points beyond the limits of routine state inspection on the condition that the milk sanitation rating officer be certified by the FDA. Such inspection in Canada would conform to the guiding principle of Article 708.d of the FTA - the use of the other country's personnel for testing and inspection of agricultural products, where appropriate.
