What is Shell Cassida®?

Shell Cassida® is a global line of food grade lubricants. These are synthetic, high performance lubes and greases that are all qualified as NSF H1 lubricants for incidental contact with food. Shell Cassida® lubricants are also registered with the Canadian Food Inspection Agency (CFIA).

Why should food manufacturers change from conventional mineral oils to food grade lubricants?

There are two basic reasons – safety and improved performance. It is virtually impossible to guarantee that lubricants used in food manufacturing plants don’t come into contact with the food products. By switching to food grade Shell Cassida®, food manufacturers can have peace of mind should the worst occur. This protects the manufacturers hard won reputation. Secondly, high-grade synthetic lubricants, such as Shell Cassida®, have superior performance to conventional mineral oils resulting in improved protection and lower overall plant maintenance costs.

What regulatory standards, for food lubricants, does Shell Cassida® meet?

All products in the Shell Cassida® range comply with the NSF International H1 qualification. This is the standard that has replaced the previous USDA system for lubricants where incidental contact with food is likely. Additionally, all Cassida® products comply with FDA 21 CFR 178.3570 and are approved for food plant use by the Canadian Food Inspection Agency (CFIA).

What is HACCP?

The Hazard Analysis and Critical Control Point System (HACCP) dates back to the 1960s when it was developed by NASA in order to make risk-free food for astronauts. NASA identified points where contamination was likely to occur so that appropriate process controls could be implemented during production. That system is now federally mandated in the USA for use as a critical contamination prevention program under the Food Safety Initiative in seafood and meat and poultry processing facilities. The Canadian Food Inspection Agency’s (CFIA) Food Safety Enhancement Program (FSEP) encourages the development, implementation and maintenance of HACCP systems in all federally registered establishments of the meat, dairy, honey, maple syrup, processed fruit and vegetable, shell egg, processed egg and poultry hatchery sectors. HACCP implementation is mandatory in all Canadian establishments registered under the Meat Inspection Act, and federally registered fish and seafood processing establishments are required by regulation to have HACCP systems in place.

How can lubricants make their way into food during the manufacturing process?

Sadly, all too easily. Oil droplets can fling off machinery in fast-moving applications or grease can drip from bearings or conveyors. Critical Control Points – can seamers, bakery ovens, conveyors and the like – are of particular concern. Also, contamination can occur at any point through simple human error or equipment failure, such as hydraulic hose failure.

Is it OK to use Shell Cassida® only in critical points on the production line?

Critical control points are the most important, but many plants choose to introduce food grade lubricants throughout for peace of mind. Remember Murphy’s Law – if it can happen, it will.

Is Shell Cassida® suitable for use in all types of food production?

Shell Cassida® products have been approved for the preparation of Kosher as well as Halal foods and are also suitable for vegetarian food production. The entire range contains neither nut products nor materials derived from genetically modified organisms (GMO's).

What are the properties that make Shell Cassida® a food grade lubricant?

Basically, Shell Cassida® is harmless if accidentally consumed in quantities below the maximum prescribed level. The US FDA (Food and Drug Administration) approves all the components of lubricants as indirect food additives. As lubricants are not designed to be consumed there is a prescribed maximum amount that is allowed to be present in food, namely 10 ppm (10 parts per million).

How does Shell Cassida® perform under difficult conditions including heat and moisture?

Shell Cassida® can not only take it, but performs better under these difficult conditions than mineral oil-based products or many other food-grade lubricants. Shell Cassida® oils and greases are synthetic which provides improved lubrication performance. The grease thickener offers excellent water resistance as well.

How easy is it to switch to Shell Cassida®?

Changing to Shell Cassida® is easy. Simply remove all the old oil and thoroughly clean and flush the equipment with new oil. This needs to be done to keep contamination with the old oil to a minimum. Shell Cassida® lubricants are fully compatible with common seals, paint finishes, sight glass and polymer window materials.

What can be done with the used oil?

Like any other used oil, Shell Cassida® should be disposed of responsibly, for example by burning the hydrocarbons to recycle energy or re-refining the oil itself. If it is very clean, it may have a higher value as a waste oil feedstock for re-refining than for burning.
