To keep pace with an aging population, an increase in chronic and infectious diseases, and the ever-growing need to comply with various government regulations, the pharmaceutical industry is investing more heavily in processing equipment.1 For many companies, purchasing used manufacturing equipment presents an excellent opportunity to implement necessary technology in a more cost-effective manner and with shorter lead times (it can sometimes take upwards of a year to manufacture new equipment).
Customers purchasing used equipment need complete assurance that the machinery presents no risk of cross contamination. Conducting microbial testing and biological decontamination of used equipment — before it is placed into service — offers peace of mind to customers who are worried about bringing an outside system into existing aseptic or controlled manufacturing conditions.
Microbial testing and equipment decontamination can be offered as a value-added service by an NIH-credentialed bio-decontamination company, providing value by saving manufacturers time and money. While some drug makers may have a decontamination program, the process of decontamination usually occurs in a dedicated area. It is often not practical to bring a used piece of machinery into that area, as it poses the risk of contamination. The decontamination company will perform microbial testing and biological decontamination prior to shipping the used equipment — along with all of the supporting validation documentation.
While a company should have Good Manufacturing Practices (GMPs) unique to itself and/or dictated by FDA regulations or USP guidelines, manufacturers of biopharmaceutical and pharmaceutical finished products must demonstrate that harmful residues or organisms are properly removed to predetermined safety levels.2 A three-step decontamination process will ensure that used equipment is free from beta-lactam antibiotics as well as destroy up to 99.9999% of harmful pathogens and contaminates.
1. β-lactam (beta-lactam) Antibiotic Testing
In pharmaceutical manufacturing, β-lactam and non- β-lactam production must be segregated due to the concern that a portion of the population is sensitive to broad-spectrum antibiotics like Penicillin G and Ampicillin, with serious health consequences if cross contamination occurs. It is important to note that a used equipment seller should not even accept pharmaceutical equipment into its facility without validation of what it had previously been used to manufacture. Any equipment that was used for β-lactam production should not be bought and resold unless the buyer is aware of the prior use and intends to use the equipment to manufacture the same product. β-lactam testing provides additional assurance to customers with heightened concerns of the machinery’s prior use.
To confirm that critical β-lactam compounds are absent from product contact surfaces of the equipment, the following steps are taken:
The bio-decontamination company will assist the client in determining which process is most appropriate. The goal is to select the least expensive option that will achieve the desired consequence.
3. Validation Performance Compliance
Upon completion of the equipment decontamination process, and after receipt of the β-lactam lab analysis, an extensive report validating the mechanical, chemical and biological performance is issued to the pharmaceutical manufacturer. The validation should be placed in a file in the event of an internal or FDA audit.3 The report is consistent with GMP compliance standards and follows the guidelines mandated by the associated decontamination equipment manufacturer.
In addition to decontaminating used equipment prior to shipping, a decontamination company can go to a customer’s site to decontaminate equipment or complete facilities. This alleviates the customers’ burden or expense of having to purchase decontamination equipment, maintain it and train people to use it. Instead, they can subcontract the process, saving both time and money.
Common Equipment Contaminants
Decontamination services can be scheduled on a pre-determined or emergency basis. The frequency becomes more pronounced in the case of a Contract Development and Manufacturing Organization (CDMO) that works for multiple clients and makes multiple changes in what it produces. CDMOs have to ensure the item produced prior doesn’t cross contaminate the next batch, which may be a different product altogether. In these cases, decontamination between batches of different products is essential.
