They were commenting on Economy and Innovation Minister Ausrine Armonaite's call on supermarket chains to voluntarily limit their range of non-essential items to reduce shopper numbers and not to have a competitive advantage over retailers that sell only non-food products and were ordered to close as part of the lockdown.
Norfa spokesman Darius Ryliskis told BNS that removing non-food products from the shelves would require major software changes, which would adversely affect the chain's operations.
"Software changes of this size may have unintended consequences, create chaos during the festive season and cause serious damage to the company," he said.
Ernesta Dapkiene, head of communications at Maxima, said she did not think that such a measure would help reduce customer flows.
"Food products make up the absolute share of sales at Maxima stores," she told BNS. "Currently, we have no suitable solution for restricting non-food items. All options would cause even more confusion in an already difficult situation."
Lidl spokeswoman Lina Skersyte said the company had yet made no decisions regarding the minister's call.
Renata Kersiene, head of public relations at Rimi Lithuania, told BNS on Thursday that the chain was not considering such restrictions at its stores.
Iki, another major supermarket chain, refused to comment in detail, saying only that foodstuffs make up the bulk of products in its stores.
Armonaite said on Thursday that if necessary, the government could order supermarket chains to non-essential items off shelves.
